Millions of Americans are under threat of a devastating tsunami following a massive 8.8 magnitude earthquake that struck off the coast of Russia.

Emergency sirens sounded throughout Hawaii, prompting residents to leave coastal regions as the island chain prepared for the anticipated impact expected at 1 am EST or 7 pm local time.

Locals were seen running to supermarkets to stock up on water and other essentials as Gov. Josh Green signed an emergency proclamation for the state.

Images shared online depicted heavy traffic on a Honolulu highway as people rushed to reach elevated areas. On the island of Oahu, the US Army and Navy facilitated evacuations by opening Kolekole Pass and parts of Schofield Barracks.

Tsunami advisories were issued along the entire US West Coast, while Japan faced a tsunami threat, leading to an evacuation of workers from the Fukushima nuclear plant.

Waves were expected to reach California at about 3 am EST/12 am local.

Data from the US Geological Survey shows the quake reached a magnitude of 8.8 and struck about 84 miles east-southeast of Kamchatska, Russia at around 7.24pm EST – marking the sixth strongest earthquake ever.

It was also believed to be the strongest to strike on the entire planet in 14 years, when a 9.1 megaquake hit northeast Japan and left 19,747 people either dead or missing.

Several were injured in Russia and kindergarten in Petropavlovsk collapsed from the quake as tsunami waves could be seen reaching the Petropavlovsk-Kamchatsky.

‘Unfortunately, there are some people injured during the seismic event. Some were hurt while running outside, and one patient jumped out of a window. A woman was also injured inside the new airport terminal,’ Oleg Melnikov, regional health minister told Russia´s TASS state news agency.

‘All patients are currently in satisfactory condition, and no serious injuries have been reported so far.’

The Kamchatka branch of the Geophysical Service of the Russian Academy of Sciences also said it was a very powerful earthquake.

‘However, due to certain characteristics of the epicenter, the shaking intensity was not as high … as one might expect from such a magnitude,’ it said in a video on Telegram.

‘Aftershocks are currently ongoing … Their intensity will remain fairly high. However, stronger tremors are not expected in the near future. The situation is under control.’

But in Hawaii, the Department of Emergency Management for Oahu, an island of Hawaii, urged residents on the coast to evacuate the area or at least move to higher ground ahead.

Officials in Guam also urged residents to get off the beaches and harbors.

The tsunami ‘could be destructive’ to coastal areas, authorities at the Pacific Tsunami Warning Center warned. 

The warning added that ‘waves reaching more than three meters above the tide level [or about 10 feet] are possible along some coasts of Northwestern Hawaiian Islands.’

The National Weather Service also warned residents they ‘are in danger.’

‘Get away from coastal waters. Move to high ground or inland now. Keep away from the coast until local officials say it is safe to return,’ the department said in an alert. 

Meteorologist Matthew Cappucci also urged Americans to ‘prepare to evacuate vertically if warnings are issued.’

‘Move away from beaches, harbors, marinas, bays and inlets. If you’re in a boat and cannot reach shore, sail away from the coast into deeper waters where the tsunami’s energy will be dispersed. Head to a place with an ocean depth of at least 180 feet.’

The quake reached a magnitude of 8.8 and struck about 84 miles east-southeast of Kamchatska at around 7.24pm EST

The earthquake on Tuesday came just over one week after several other tremors struck the area, including one that measured a 7.4 magnitude. 

Tuesday’s earthquake is the largest this year, and is the first magnitude 8.0 or higher since 2021.

An 8.8 magnitude earthquake previously hit Ecuador in 1906, killing 1,500 people with impacts reaching as far north as San Francisco. More recently, an 8.8-magnitude quake stuck Chile in 2010, killing 523 people and destroying more than 370,000 homes.

An 8.7-magnitude earthquake that struck near the Rat Islands of Alaska’s Aleutian Islands in 1965 also generated a tsunami that was reportedly 35 feet high. 

Kamchatka and Russia’s Far East sit on the Pacific Ring of Fire, a geologically active region that is prone to major earthquakes and volcanic eruptions.
