The massive 8.8 earthquake off Russia’s coast, which prompted tsunami warnings that sent coastal dwellers as far away as Southern California inland late Tuesday night, is one of the largest ever recorded. It is the largest seismic event to occur globally since the 9.0 Tohoku, Japan, earthquake in 2011... “According to a live update from CNN World, so far the highest reported tsunami waves on the West Coast as of 5:30 a.m. PT have been 5.7 feet in Kahului, Hawaii, 4 feet in Crescent City, California, and 3 feet in Arena Cove, California, the New York Post said. The Russian temblor was the sixth-biggest quake ever recorded, Simon Boxall, a principal teaching fellow at the University of Southampton’s Physical Oceanography Research Center, told the New York Post. The largest earthquake ever recorded was a 9.5 magnitude quake in the central region of Chile in 1960. It resulted in more than 1,600 deaths in the country and elsewhere. The second largest was in the United States. In 1964 a 9.2 magnitude earthquake jolted the Prince William Sound in Alaska and lasted for almost 5 minutes, resulting in 130 deaths. https://www.breitbart.com/europe/2025/07/30/russian-earthquake-sixth-largest-seismic-history/ A strong earthquake registered by the USGS as M6.8 struck east of the Kamchatka Peninsula, Russia, at 05:37 UTC on August 3, 2025. The agency reports a depth of 35 km (22 miles), while the EMSC lists the same magnitude at a depth of 25 km (16 miles). This event is part of the ongoing aftershock sequence following the tsunami-generating M8.8 earthquake that occurred at 23:24 UTC on July 29. This earthquake is part of a strong aftershock sequence following the M8.8 megathrust earthquake that struck off the Kamchatka Peninsula at 23:24 UTC on July 29, 2025. Since that mainshock, multiple significant aftershocks (M6+) have been recorded across the region, particularly east and southeast of Severo-Kuril’sk and south of Vilyuchinsk. A total of 426 earthquakes of magnitude 4.0 and above have been recorded along the Kamchatka Peninsula and northern Kuril Islands region over the past 7 days. The Krasheninnikov volcano erupted for the first time in 600 year on August 3, 2025, sending an ash plume 6 km (19 700 feet) into the sky. Scientists suggest that the eruption might have been linked to the M8.8 earthquake that struck the Kamchatka peninsula on July 30. The Krasheninnikov volcano in Russia erupted for the first time in 600 years at 02:50 LT on August 3 (16:50 UTC on August 2), just days after a massive M8.8 earthquake struck the region, generating shockwaves and tsunamis worldwide. “This is the first historically confirmed eruption of Krasheninnikov volcano in 600 years,” said Olga Girina, head of the Kamchatka Volcanic Eruption Response Team (KVERT). ...subsequent reports from the Kamchatka branch of Russia’s Ministry of Emergency Situations (EMERCOM) stated that the plume reached an altitude of 6 km (19,700 feet) a.s.l.
