A magnitude 8.8 earthquake struck off Russia's Far Eastern Kamchatka Peninsula on Wednesday, generating a tsunami of up to 4 metres (13 feet), damaging buildings and prompting evacuation warnings in the area and across most of Japan's east coast.
The earthquake off the Kamchatka Peninsula on Wednesday was the strongest since 1952 and triggered dangerous tsunami waves along the coast, the Kamchatka branch of the Geophysical Service of the Russian Academy of Sciences said.
"Given the scale of this event, we should expect strong aftershocks, possibly with magnitudes up to 7.5," the Service said in a statement on the Telegram messaging app.
"Significant, noticeable aftershocks with magnitudes up to 7.5 are expected to continue for at least another month." (Reuters)
Russia: Warnings were issued for two of the Kuril islands, Paramushir and Shumshu, and the Kamchatka region.
Japan: Authorities in Japan said the height of the tsunami along the country’s Pacific coast could reach 3 meters, or 10 feet. A ferry linking the main Japanese islands of Honshu and Hokkaido was suspended, Japan’s public broadcaster NHK reported.
China: Eastern parts of China is likely to be affected too, with one metre high waves expected in the eastern seaboard.
Long reach: The impact of the quake rippled across vast stretches of the Pacific Ocean, sparking warnings for Hawaii and Alaska, and prompting advisories as far away as Mexico and Chile, where the US Tsunami Warning System warned that waves could be nearly 10 feet high.
"Due to a massive earthquake that occurred in the Pacific Ocean, a Tsunami Warning is in effect for those living in Hawaii. A Tsunami Watch is in effect for Alaska and the Pacific Coast of the United States. Japan is also in the way. Please visit https://tsunami.gov for the latest information. STAY STRONG AND STAY SAFE!," the US President posted.
"Indian nationals in California, other US West Coast states, and Hawaii are advised to take the following steps:-
▶️Follow Local Alerts: Carefully monitor alerts from US authorities, including local emergency management and the US Tsunami Warning Centers.
▶️Move to higher ground if Tsunami Alert is issued.
▶️Avoid Coastal Areas.
▶️Prepare for Emergency & Keep devices charged.

“If you are in a coastal area, move inland and to higher ground immediately. Do not wait,” he said. (NYT)
The colossal magnitude 8.8 earthquake off Russia’s coast early Wednesday is set to be one of the largest ever recorded if its magnitude is not revised down by scientists studying the data.
The quake is tied for the sixth-largest on record, according to the US Geological Survey. It is the most powerful since the 2011 earthquake off Japan’s east coast, which triggered the Fukushima tsunami and nuclear disaster.
That quake, which had a magnitude of 9.1, was about 2.8 times stronger than Wednesday’s. It killed more than 15,000 people and displaced 130,000 more, and created a tsunami 50 feet tall that rushed inland for miles with the speed of a locomotive, swallowing everything in its path and flooding more than 200 miles of shoreline.
For each whole-number increase in magnitude, the seismic energy released by a quake increases by about 31.6 times, according to the US Geological Survey. This means that a magnitude 8.8 earthquake produces about 31.6 times more energy than a magnitude 7.8 quake.
The strongest earthquake ever recorded, according to the US Geological Survey, was the magnitude 9.5 quake off the coast of Chile in 1960. It killed 1,655 people and displaced 2 million more. (NYT)

Residents across Japan's Pacific coast rushed to higher ground on Wednesday as tsunami warnings following a massive earthquake off Russia's Far East resurfaced painful memories and lessons from the devastating 2011 earthquake and nuclear disaster.
Television banners flashed "TSUNAMI! EVACUATE!" and similar warnings as most broadcasters cut regular programming to issue warnings and focus on evacuation orders, as tsunami waves approached Japan's shores.
"Do not be glued to the screen. Evacuate now!" a news presenter at public broadcaster NHK shouted.
The warnings resurfaced memories of the March 11, 2011, earthquake, when more than 15,000 people died after a 9.0-magnitude tremor triggered a massive tsunami that tore through the Fukushima nuclear power plant and caused a radioactive disaster.
A major tsunami is not expected to strike Hawaii, the Pacific Tsunami Warning Centre (PTWC) said, hours after an alert was issued.
