rupture was 600 km (373 miles). Aftershocks were recorded in an area of approximately 247,000 km2 (90,367 square miles), at depths of between 40 and 60 km (25 and 37 miles). A recent analysis of the tsunami runup distribution based on historical and geological records give some indication as to the slip distribution of the rupture. 1959 earthquake A magnitude 8.0 earthquake occurred on May 4, at a hypocentral depth of 20 km, with a maximum felt intensity of VIII MSK. 2006 earthquake The region of Koryak Autonomous Okrug was struck by an 7.6 earthquake on April 20 (April 21 local time). It was followed by a large number of aftershocks, including two of 6.6. This was a reverse faulting event along the boundary between two microplates within the North American Plate. The event caused a 140 km long zone of surface rupture. 2020 earthquake The 7.5 earthquake occurred on March 25. The earthquake was the largest to occur in Russia since the 2013 Okhotsk Sea earthquake. It was initially reported as 7.8 , before being downgraded to 7.5. This shock was a result of near-trench intraplate compressional faulting within the descending Pacific Plate. The epicenter was in the area of the large-slip region of the 1952 Severo-Kurilsk earthquake, which was an M 9.0 megathrust event. Large compressional activity is more common before, and long after, major compressional events along coupled zones, suggesting interplate strain accumulation. In Petropavlovsk-Kamchatsky, 285 miles (460km) away from the epicenter the intensity was felt at 5, objects were falling in buildings and people ran out into the street for safety. A tsunami warning was issued immediately after the earthquake. The Pacific Tsunami Warning Centre initially said hazardous tsunami waves were possible within 1,000km of the earthquake’s epicentre. It said earthquakes of this strength in the past had caused tsunamis far from the epicentre. A tsunami of about struck Kamchatka.
