richter magnitude scale

Published

on

The Richter mag­ni­tude of an earth­quake is de­ter­mined from the log­a­rithm of the am­pli­tude of waves recorded by seis­mo­graphs (ad­just­ments are in­cluded to com­pen­sate for the vari­a­tion in the dis­tance be­tween the var­i­ous seis­mo­graphs and the epi­cen­terof the earth­quake). Earthquake Magnitude Levels Vector Illustration Diagram . The effective limit of measurement for local magnitude is about . Investigators have proposed extensions to the local magnitude scale, the most popular being the surface wave magnitude mS and the body wave magnitude mb. The following describes the typical effects of earthquakes of various magnitudes near the epicenter. 10 mins read . Scientists abandoned the Richter scale in favor of the moment magnitude scale. The Richter scale and how it measures earthquake magnitude. The scale abandoned the use of peak wave amplitudes in its calculations, focusing instead on calculating an earthquake’s seismic moment (M0)—that is, the displacement of the fault across its entire surface multiplied by the force used to move the fault. Each increase of one unit also represents the release of about 31 times more energy than that represented by the previous whole number on the scale. The Richter scale is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude. An official from MeT Department said that the tremors were felt at 10:58 a.m. Winter 2021 . Whenever we hear of an earthquake, its magnitude is always explained in terms of the Richter scale. In the decades that followed the creation of the original Richter scale, they developed the body-wave magnitude scale (mb, which calculates the magnitude of primary, or P, and secondary, or S, seismic waves traveling within Earth) and the surface-wave magnitude scale (MS, which calculates the magnitude of Love and Rayleigh waves traveling along Earth’s surface). Feeding Frenzy. Please select which sections you would like to print: Corrections? ML=log10⁡A−log10⁡A0(δ)=log10⁡[A/A0(δ)],{\displaystyle M_{\mathrm {L} }=\log _{10}A-\log _{10}A_{\mathrm {0} }(\delta )=\log _{10}[A/A_{\mathrm {0} }(\delta )],\ } where A is the max­i­mum ex­cur­… Magnitude Intensity Pacific Northwest Seismic Network . It was developed by Charles F. Richter and presented in his landmark 1935 paper. Noticeable shaking of indoor items, rattling noises. It is a base-10 logarithmic scale. Wood et Frank Neumann en 1931. In 1935, Richter presented a scientific paper on his Local Magnitude Scale. Take your favorite fandoms with you and never miss a beat. Richter Magnitude Scale pour 33,33 €. The Richter Scale. Events with magnitudes of about 4.6 or greater are strong enough to be recorded by any of the seismographs in the world, given that the seismograph's sensors are not located in an earthquake's shadow. The scale was later revised and renamed the local magnitude scale, denoted as ML or ML. The Richter scale of earthquake magnitude is listed in the table. The Richter scale is a scale of numbers used to tell the power (or magnitude) of … Thus, a difference in magnitude of 1.0 is equivalent to a factor of 31.6 () in the energy released; a difference of magnitude of 2.0 is equivalent to a factor of 1000 ( ) in the energy released. This figure is calculated on the basis of the tremors caused at that time, as well as the energy that was released by the tremors. If you would like to participate, you can choose to edit this article, or visit the project page for more information. However, Richter’s Magnitude Scale had several problems. The epicentre was Bandipora, he said. His inspiration was the apparent magnitude scale used in astronomy to describe the brightness of stars and other celestial objects. Get a Britannica Premium subscription and gain access to exclusive content. The shortcomings inherent in the original Richter scale spawned the development of improved Richter scales by Richter and Gutenberg. assigns a magnitude number to quantify the energy released by an earthquake. Il a été créé à l'origine pour étudier une région particulière de la Californie, à l'aide du sismographe de torsion W… Present-day seismographs, however, may be calibrated to compute Richter magnitudes, and modern methods for measuring earthquake magnitude have been developed to produce results that remain consistent with those measured using the Richter scale. San Francisco Bay Area earthquake (CA, USA), 1989, Japan Meteorological Agency seismic intensity scale, USGS: List of World's Largest Earthquakes, IRIS Real-time Seismic Monitor of the Earth, https://earthquakes.fandom.com/wiki/Richter_magnitude_scale?oldid=3790. Let us know if you have suggestions to improve this article (requires login). 05:54 (IST) Dec 25. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations. For example, an earthquake with a magnitude of two is ten times more intense than those with a magnitude of one, and so on. He serves currently as the editor of Earth and life sciences, covering climatology, geology, zoology, and other topics that relate to... Schematic diagram of a 1924 Anderson-Wood torsion pendulum seismograph, the type used by seismologist Charles F. Richter to define his earthquake magnitude scale. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Most seismological authorities now use other scales to report earthquake magnitudes. L’échelle d’intensité de Mercalli a été développée par le volcanologue italien Giuseppe Mercalli en 1884 et élargie pour inclure une intensité de 12 degrés en 1902 par Adolfo Cancani. The largest recorded earthquake was the Great Chilean Earthquake of May 22, 1960 which had a magnitude (MW) of 9.5.[3]. Devastating in areas several thousand miles across. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; in terms of energy, each whole number increase corresponds to an increase of about 31.6 times the amount of energy released. Moment magnitude calculations, however, continue to express earthquake magnitude using a logarithmic scale, which allows its results to compare favorably with those of other scales below magnitude 8. Because of limitations imposed by seismographs and the emphasis on measuring a single peak amplitude, the Richter scale underestimates the energy released in earthquakes with magnitudes greater than 6.5, since the values calculated after measuring very large seismic waves tend to cluster, or “saturate,” near one another. Earthquake of magnitude 6.2 on the Richter scale hit Manila, Philippines at 5:13 am today: National Centre for Seismology. The coordinates of the earthquake were 74.52 degrees East and 34.28 degrees North. According to Index.hr, at 6:16 am, Croatia was hit by an earthquake with a magnitude of 4.9 on the Richter scale, according to EMSC data, with the epicenter 18 kilometers west of Sisak. This choice was intended to prevent negative magnitudes from being assigned. Richter Scale Chart Showing Damage Caused Earthquake . Achetez maintenant! Each increase of one unit on the scale represents a 10-fold increase in the magnitude of an earthquake. In other words, numbers on the Richter scale are proportional to the common (base 10) logarithms of maximum wave amplitudes. Richter scale (ML), quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake). It is a base-10 logarithmic scale obtained by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a Wood–Anderson torsion seismometer output. (That was the Richter magnitude for the Chile earthquake of 1960. Toba eruption 75,000 years ago; which, according to the Toba catastrophe theory, affected modern human evolution, Estimate for a 2 km (~1.2 mi) rocky meteorite impacting at 25 km/s (~55,000 mph). This magnitude scale was referred to as ML, with the L standing for local. The Richter magnitude Scale, or more correctly, local magnitude M L Scale, assigns a single number to quantify the amount of seismic energy released by earthquake. No damage was reported. This means each step of magnitude is ten times more intense than the last. Developed in 1935 by Charles Richter in partnership with Beno Gutenberg, both of the California Institute of Technology, the scale was firstly intended to be used only in a particular study area in California, and on seismograms recorded on a particular instrument, the Wood-Anderson torsion seismometer. So, for example, an earthquake that measures 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. It was designed to produce a more-accurate measure of the total energy released by an earthquake. Can cause major damage to poorly constructed buildings over small regions. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. The Hiroshima atomic bomb was 15 kilotons ), Little Skull Mtn. Richter set up a magnitude scale of earthquakes as the logarithm to base 10 of the maximum seismic wave amplitude (in thousandths of a millimetre) recorded on a standard seismograph (the Wood-Anderson torsion pendulum seismograph) at a distance of 100 km (60 miles) from the earthquake epicentre. Earthquake Magnitude Scales Describes the scales scientists use to indicate the intensity and magnitude of an earthquake including the Mercalli, Richter, and moment magnitude. Charles F. Richter devised his magnitude scale in the mid-1930s while investigating earthquakes in California. The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake). The Richter scale was originally devised to measure the magnitude of earthquakes of moderate size (that is, magnitude 3 to magnitude 7) by assigning a number that would allow the size of one earthquake to be compared with another. Richter scale (M L), quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. All this is calculated with the help of a formula, as explained below. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. The table below sets this out and describes how each level of an earthquake feels: Progress At most slight damage to well-designed buildings. Magnification of its movements for recording purposes was made possible by use of a mirror (m). Magnitude calculations are dependent on the earthquake being local, as well as on the use of one particular type of seismograph. The moment magnitude (MW or M) scale, developed in the late 1970s by Japanese seismologist Hiroo Kanamori and American seismologist Thomas C. Hanks, became the most popular measure of earthquake magnitude worldwide during the late 20th and early 21st centuries. He invented it in 1935 to compare the sizes of earthquakes. This was later revised and renamed the local magnitude scale, denoted as ML or M L. [1]. TRENDING STORIES View All. Moreover, in September, a medium-intensity earthquake of magnitude 5.4 hit the Ladakh region. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Richter originally reported values to the nearest quarter of a unit, but decimal numbers were used later. The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. Can cause serious damage over larger areas. Since the moment magnitude scale was not limited by Richter’s process, it avoided the saturation problem and thus was used to determine the magnitudes of the largest earthquakes. Both scales, however, suffered from saturation when used to measure earthquakes of magnitude 8 and above. The Richter worked best for southern California earthquakes, and for only those hitting within 370 miles of a seismometer. Updates? The energy release of an earthquake, which equates to its destructive power, scales with the 3⁄2 power of the shaking amplitude. Earthquake of magnitude 2.3 on the Richter scale … Richter magnitude: Description: Earthquake effect < 2.0 Micro Micro earthquakes, not felt. Lower magnitude events (based on the Richter scale) occur more often than higher [...] magnitude events, and generally are expected to produce lower damage figures. The earthquake’s magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph . John P. Rafferty writes about Earth processes and the environment. Never recorded; see below for equivalent seismic energy yield. The Richter scale is a base-ten logarithmic scale. Omissions? Reduction of amplitudes…. For instance, the one that hit Haiti in 2010, measured 7.0 on this scale. Richter arbitrarily chose a magnitude 0 event to be an earthquake that would show a maximum combined horizontal displacement of one micrometre on a seismograph recorded using a Wood-Anderson torsion seismometer 100 kilometres (62 mi) from the earthquake epicenter. How to determine the richter magnitude of an earthquake from its seismogram. He used seismographs which magnified ground motion 2800 times, and as a baseline, he defined a magnitude 0 earthquake as being one that would produce a record with an amplitude of one-thousandth of a millimeter at a distance of 100 kilometers from the epicenter (such … Bandipora, Jan 04: An earthquake of magnitude 3.5 on the Richter Scale hit Bandipora at arround 10:58 am today. Il a été modifié à nouveau par Harry O. JUXTAPOZ. )[2], Great earthquakes occur once a year, on average. In response to oscillations of the ground caused by an earthquake, the pendulum swung in a nearly horizontal plane around the wire, its own free oscillation being reduced, or damped, by the magnetic field. The orig­i­nal for­mula is: 1. Can cause serious damage in areas several hundred miles across. The Richter magnitude scale is a measure of the strength of earthquakes. The Himalayan region is known for high seismic activities. Nagasaki atomic bomb (actual seismic yield was negligible since it detonated in the atmosphere. It is base-10 logarithmic Scale obtained by calculating logarithm of combined horizontal amplitude of largest displacement from zero on Wood–Anderson torsion seismometer output. The Richter scale – also called the Richter magnitude scale or Richter's magnitude scale – is a measure of the strength of earthquakes, developed by Charles F. Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". The Richter Magnitude Scale (ML) is a measure of the strength of earthquakes that was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. Earthquakes Wiki is a FANDOM Lifestyle Community. (Many scientists and historians feel it should be known as the Richter–Gutenberg scale.) Using The Richter Scale To Measure Earthquakes Earthquake . High Richter magnitude scale is part of WikiProject Geology, an attempt at creating a standardized, informative, comprehensive and easy-to-use geology resource. This table should be taken with extreme caution, since intensity and thus ground effects depend not only on the magnitude, but also on the distance to the epicenter, the depth of the earthquake's focus beneath the epicenter, and geological conditions (certain terrains can amplify seismic signals). On the original Richter scale, the smallest earthquakes measurable at that time were assigned values close to zero on the seismograph of the period. Our editors will review what you’ve submitted and determine whether to revise the article. SRINAGAR: A low-intensity quake measuring 3.5 on the Richter Scale was felt in Kashmir early on Monday. Amani Lewis – More Blessed to Give. Richter applied a logarithm where each step in the scale represented ten times the force of the previous step. The following table lists the approximate energy equivalents in terms of TNT explosive force[4] - though note that the energy here is that of the underground energy release (ie a small atomic bomb blast will not simply cause light shaking of indoor items) rather than the overground energy release; the majority of energy transmission of an earthquake is not transmitted to and through the surface, but is instead dissipated into the crust and other subsurface structures. Earthquake in Jammu and Kashmir: Quake of Magnitude 3.5 on Richter Scale Hits Bandipora District. The scale was developed for temblors occuring in southern California that were recorded using the Wood-Anderson seismograph and whose epicentres were less than 600 km (373 miles) from the location of the seismograph. Earlier in December, an earthquake measuring 3.7 hit Jammu and Kashmir, the National Center for Seismology had informed. Main article: Richter magnitude scale The first scale for measuring earthquake magnitudes, developed in 1935 by Charles F. Richter and popularly known as the "Richter" scale, is actually the Local magnitude scale, label ML or M L. Richter established two features now common to all magnitude scales. The surface-wave magnitude scale also had no distance restrictions between the earthquake epicentre and the location of the seismograph, and the body-wave magnitude scale, with its approximately 1,000-km (620-mile) range, was viewed as accurate enough to measure the few relatively small earthquakes that occurred in eastern North America. The earthquake’s magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph. However, the Richter scale has no upper or lower limit, and sensitive modern seismographs now routinely record quakes with negative magnitudes. earthquake (NV, USA), 1992, Double Spring Flat earthquake (NV, USA), 1994. The Richter scale calculates an earthquake's magnitude (size) from the amplitude of the earthquake's largest seismic wave recorded by a seismograph. Ring in the new year with a Britannica Membership, https://www.britannica.com/science/Richter-scale, generally not felt by people, though recorded on local instruments, serious damage over large areas; loss of life, severe destruction and loss of life over large areas. A small copper cylinder (C) was attached to a tungsten wire (T) between the poles (N, S) of a U-shaped permanent magnet. The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6. C This article has been rated as C-Class on the project's quality scale. (Based on U.S. Geological Survey documents. World Central Kitchen, founded by chef José Andrés, has … Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; in terms of energy, each whole number increase corresponds to an increase of about 31.6 ti… The Richter scale doesn't measure quake damage (see: Mercalli Scale) which is dependent on a variety of factors including population at the epicentre, terrain, depth, etc.An earthquake in a densely populated area which results in many deaths and considerable damage may have the same magnitude as a shock in a remote area that does nothing more than frightening the wildlife. Earthquake Magnitude Scale . Because of the limitations of the Wood-Anderson torsion seismometer used to develop the scale, the original ML cannot be calculated for events larger than about 6.8. ...The Richter scale was the brainchild of Caltech seismologist Charles Richter. Richter scale. This was an attempt to define the “size” of earthquakes. This is what was to eventually become known as the Richter magnitude. The earthquake’s magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph. In addition, the Richter scale could not be used to calculate the total energy released by an earthquake or describe the amount of damage it did. Richter … The Richter magnitude scale, or more correctly local magnitude ML scale, assigns a single number to quantify the amount of seismic energy released by an earthquake. Can be destructive in areas up to about 160 kilometres (100 mi) across in populated areas. La magnitude est en sismologie la représentation logarithmique du moment sismique, qui est lui-même une mesure de l'énergie libérée par un séisme. For Amani Lewis, the portraits are much more than a likeness. LIVRAISON GRATUITE - SANS VALEUR MINIMALE - PAIEMENT SÉCURISÉ - GRANDE SÉLECTION - PETIT PRIX An earthquake of magnitude 3.5 on the Richter Scale hit Bandipora in Jammu and Kashmir at 10:58 am today: National Center for Seismology These traditional magnitude scales have largely been superseded by the implementation of methods for estimating the seismic moment and its associated moment magnitude scale. Although both scales continued to make use of seismographs and peak wave amplitudes, they became relatively reliable ways to calculate the energy of all but the largest earthquakes. His motivation for creating the local magnitude scale was to separate the vastly larger number of smaller earthquakes from the few larger earthquakes observed in California at the time. (That is, an earthquake measuring 5.0 releases 31 times more energy than an earthquake measuring 4.0.) The Richter magnitude scale, also known as the local magnitude scale, assigns a single number to quantify the amount of seismic energy released by an earthquake. Significant damage unlikely. Il est aujourd'hui connu sous le nom d'échelle d'intensité modifiée de Mercalli.. La Richter Magnitude Scale a été développée en 1935 par Charles Richter. The Richter magnitude scale, also known as the local magnitude (M) scale, assigns a number to quantify the amount of seismic energy released by an earthquake. Richter Scale Magnitude . More reports awaited. Energy released was equivalent to that of Tsar Bomba, the largest thermonuclear weapon ever tested. Richter Magnitude Scale Explained Earthquake Magnitude . Although modern scientific practice has replaced the original Richter scale with other, more-accurate scales, the Richter scale is still often mentioned erroneously in news reports of earthquake severity as the catch-all name for the logarithmic scale upon which earthquakes are measured. Seismic wave data being recorded by a seismograph during an earthquake. The moment magnitude for this event was measured at 9.5.). Since modern seismographs can detect seismic waves even smaller than those originally chosen for zero magnitude, it is possible to measure earthquakes having negative magnitudes on the Richter scale. What Is A Megaquake Extreme Geological Events . For earthquakes measuring magnitude 6.5 or greater, Richter’s original methodology has been shown to be unreliable.

„Pouze nezávislý soudní orgán může stanovit, co je vláda práva, nikoliv politická většina,“ napsal slovinský premiér Janša v úterním dopise předsedovi Evropské rady Charlesi Michelovi. Podpořil tak Polsko a Maďarsko a objevilo se tak třetí veto. Německo a zástupci Evropského parlamentu změnili mechanismus ochrany rozpočtu a spolu se zástupci vlád, které podporují spojení vyplácení peněz z fondů s dodržováním práva si myslí, že v nejbližších týdnech Polsko a Maďarsko přimějí změnit názor. Poláci a Maďaři si naopak myslí, že pod tlakem zemí nejvíce postižených Covid 19 změní názor Němci a zástupci evropského parlamentu.

Mechanismus veta je v Unii běžný. Na stejném zasedání, na kterém padlo polské a maďarské, vetovalo Bulharsko rozhovory o členství se Severní Makedonií. Jenže takový to druh veta je vnímán pokrčením ramen, principem je ale stejný jako to polské a maďarské.

Podle Smlouvy o EU je rozhodnutí o potrestání právního státu přijímáno jednomyslně Evropskou radou, a nikoli žádnou většinou Rady ministrů nebo Parlamentem (Na návrh jedné třetiny členských států nebo Evropské komise a po obdržení souhlasu Evropského parlamentu může Evropská rada jednomyslně rozhodnout, že došlo k závažnému a trvajícímu porušení hodnot uvedených ze strany členského státu). Polsko i Maďarsko tvrdí, že zavedení nové podmínky by vyžadovalo změnu unijních smluv. Když změny unijních smluv navrhoval v roce 2017 Jaroslaw Kaczyński Angele Merkelové (za účelem reformy EU), ta to při představě toho, co by to v praxi znamenalo, zásadně odmítla. Od té doby se s Jaroslawem Kaczyńskim oficiálně nesetkala. Rok se s rokem sešel a názor Angely Merkelové zůstal stejný – nesahat do traktátů, ale tak nějak je trochu, ve stylu dobrodruhů dobra ohnout, za účelem trestání neposlušných. Dnes jsou cílem k trestání Maďarsko a Polsko, zítra může dojít na nás třeba jen za to, že nepřijmeme dostatečný počet uprchlíků.

Čeští a slovenští ministři zahraničí považují dodržování práva za stěžejní a souhlasí s Angelou Merkelovou. Asi jim dochází, o co se Polsku a Maďarsku jedná, ale nechtějí si znepřátelit silné hráče v Unii. Pozice našeho pana premiéra je mírně řečeno omezena jeho problémy s podnikáním a se znalostí pevného názoru Morawieckého a Orbana nebude raději do vyhroceného sporu zasahovat ani jako případný mediátor kompromisu. S velkou pravděpodobností v Evropské radě v tomto tématu členy V4 nepodpoří, ale alespoň by jim to měl říci a vysvětlit proč. Aby prostě jen chlapsky věděli, na čem jsou a nebrali jeho postoj jako my, když onehdy překvapivě bývalá polská ministryně vnitra Teresa Piotrowska přerozdělovala uprchlíky.

Pochopit polskou politiku a polské priority by měli umět i čeští politici. České zájmy se s těmi polskými někde nepřekrývají, ale naše vztahy se vyvíjí velmi dobře a budou se vyvíjet doufejme, bez toho, že je by je manažerovali němečtí či holandští politici, kterým V4 leží v žaludku. Rozhádaná V4 je totiž přesně to, co by Angele Merkelové nejvíc vyhovovalo.

Morawiecki: Hřbitovy budou na Dušičky uzavřeny

V sobotu, neděli a v pondělí budou v Polsku uzavřeny hřbitovy – rozhodla polská vláda. Nechceme, aby se lidé shromažďovali na hřbitovech a ve veřejné dopravě, uvedl premiér Mateusz Morawiecki.

„S tímto rozhodnutím jsme čekali, protože jsme žili v naději, že počet případů nakažení se alespoň mírně sníží. Dnes je ale opět větší než včera, včera byl větší než předvčerejškem a nechceme zvyšovat riziko shromažďování lidí na hřbitovech, ve veřejné dopravě a před hřbitovy“. vysvětlil Morawiecki.

Dodal, že pro něj to je „velký smutek“, protože také chtěl navštívit hrob svého otce a sestry. Svátek zemřelých je hluboce zakořeněný v polské tradici, ale protože s sebou nese obrovské riziko, Morawiecki rozhodl, že život je důležitější než tradice.

Poslankyně opozice atakovaly předsedu PiS

Ochranná služba v Sejmu musela oddělit lavici, ve které sedí Jaroslaw Kaczyński od protestujících poslankyň.

„Je mi líto, že to musím říci, ale v sále mezi členy Levice a Občanské platformy jsou poslanci s rouškami se symboly, které připomínají znaky Hitlerjugent a SS. Chápu však, že totální opozice odkazuje na totalitní vzorce.“ řekl na začátku zasedání Sejmu místopředseda Sejmu Ryszard Terlecki.

Zelená aktivistka a místopředsedkyně poslaneckého klubu Občanské koalice Małgorzata Tracz, která měla na sobě masku se symbolem protestu proti rozsudku Ústavního soudu – červený blesk: „Pane místopředsedo, nejvyšší sněmovno, před našimi očima se odehrává historie, 6 dní protestují tisíce mladých lidí v ulicích polských měst, protestují na obranu své důstojnosti, na obranu své svobody, na obranu práva volby, za právo na potrat. Toto je válka a tuto válku prohrajete. A kdo je za tuto válku zodpovědný? Pane ministře Kaczyński, to je vaše odpovědnost.“

    „Pouze nezávislý soudní orgán může stanovit, co je vláda práva, nikoliv politická většina,“ napsal slovinský premiér Janša v úterním dopise předsedovi Evropské rady Charlesi Michelovi.
