A 8.8-magnitude earthquake struck 73 miles (118 km) off the coast of Russia’s Far Eastern Kamchatka Peninsula at 11:24 a.m. PETT Wednesday, July 30 (23:24 UTC on Tuesday, July 29), the USGS said. A tsunami as tall as 13 feet (4 meters) also struck the Russian coast following the quake, the news agency Reuters reported.
The US Tsunami Warning System issued tsunami warnings and advisories for Russia, Japan, Alaska and Hawaii. The Japan Weather Agency also issued a warning. It expected tsunami waves of up to 10 feet (3 meters) to reach large coastal areas in that country starting around 01:00 UTC on Wednesday, July 30. The Associated Press reports a 1-foot (30 cm) tsunami at Nemuro on the eastern coast of Hokkaido, Japan’s second largest island.
Video footage shared via social media appears to show widespread damage on the Russian coastline.
Full video of the tsunami in Petropavlovsk-Kamchatsky, Kamchatka, Russia, following the 8.7 earthquake. Wave seems incoming and a few meters at least.

Tsunami advisories have also been issued for the Pacific coast of Canada and the US, as well as in New Zealand. The tsunami appears to be smaller than predicted in Japan, reaching 1 foot (30 cm).
Recent video footage of tsunami in Japan as waves can been seen moving down waterways. Good reports so far as they are smaller than expected. Hoping this continues…

Russian earthquake 8th largest ever recorded
Professor Alice-Agnes Gabriel of the Scripps Institution of Oceanography said the quake could be the largest since 2011 and the 8th largest ever recorded.
Magnitude 8.7 #earthquake in Kamchatka, following a M7.4 last week – may be largest earthquake since 2011, 8th largest on record globally, #tsunami warning in place for US west coast and Canada – the historic 1952 M9 closely caused a destructive tsunami across the Pacific

The earthquake was originally reported by the USGS as magnitude 8.0. However, that number was later updated to magnitude 8.8. It occurred at a depth of 13 miles (20.7 km). The epicenter was located at 52.530°N 160.165°E.
Bottom line: A magnitude-8.8 earthquake struck off the coast of eastern Russia on Wednesday, July 29. The resulting 13-foot (4-meters) tsunami struck the Russian coast.
