The 1841 Kamchatka earthquake occurred in the Pacific Ocean on May 17 at 08:00 local time. The earthquake had an epicenter off the Russian Far East's Kamchatka Peninsula. With an estimated moment magnitude of 9.0 or higher, it is one of the largest to strike the region. A large tsunami with a run-up height of up to 15 m struck the coast. Tectonic setting The earthquake occurred off the Kamchatka Peninsula's east coast, which runs parallel to the Kuril-Kamchatka Trench, the area where the Pacific and Okhotsk Sea plates converge. Being older and therefore denser, the Pacific subducts beneath the Kamchatka Peninsula, which sits on the Okhotsk Sea Plate. These two plates meet along a convergent boundary, marked by the trench. The subduction zone is seismogenic and produces Kamchatka earthquakes, which occasionally generate tsunamis; some of these megathrust earthquakes are very strong (such as the 1952 magnitude 9.0 earthquake, the fifth-largest ever recorded).20 Largest Earthquakes in the World https://www.usgs.gov/natural-hazards/earthquake-hazards/science/20-largest-earthquakes-world?qt-science_center_objects=0#qt-science_center_objects 2021-06-20 www.usgs.gov Possibly the largest to have hit the peninsula was the 1737 magnitude 9.3 earthquake which generated a large tsunami as well.Chubarov L.B. V. K. Gusiakov Tsunamis and earthquake mechanism in the island arc region Science of Tsunami Hazards 3 1 3–21 Earthquake The earthquake was associated with thrust faulting on the subduction zone near the east coast of the Kamchatka Peninsula. According to the National Centers for Environmental Information, the earthquake felt area was used to estimate its magnitude at fa 8.4. A 2004 earthquake catalog placed both the tsunami magnitude (t) and moment magnitude (w) at 9.0, based on evaluating the available tsunami data.Alexander A Gusev L.S.

According to Dr. Susan Hough of the U.S. Geological Survey, the earthquake magnitude was underestimated due to the assumption that it did not generate a large-enough tsunami. Earthquakes measuring 8.5 or greater are generally assumed to cause large tsunamis. At the American Geophysical Union fall meeting in 2013, she believes the magnitude could be up to 9.2.Rebecca Morelle Rebecca Morelle Enormous earthquakes 'are missing' from records https://www.bbc.com/news/science-environment-25329813 23 October 2021 BBC News 12 December 2013 Impact The earthquake struck the coast and was felt with a maximum intensity of VIII–IX at Petropavlovsk-Kamchatskiy. Up to 15 minutes of violent shaking was felt in the city. At least 50 stove chimneys on homes and government offices collapsed. Some homes suffered severe damage.Significant Earthquake Information https://www.ngdc.noaa.gov/hazel/view/hazards/earthquake/event-more-info/1829 ngdc.noaa.gov NOAA National Centers for Environmental Information 23 October 2021 Cliffs at the coast collapsed. Cathedral bells reportedly rang during the earthquake. The event caused a large tsunami with a maximum run-up height of 15 m 0 at the eastern coast.Joanne Bourgeois Tatiana K.
