Tsunamis hit several nations and U.S. states in the Pacific region early Wednesday morning after a massive 8.8 magnitude earthquake struck the far eastern coast of Russia.

The waves have ranged anywhere from 2 to 6 feet high, posing a possible threat to people.

Here are key details on the earthquake and tsunamis.

Where did the earthquake hit?

The earthquake hit Russia’s coastline near the southern part of the Kamchatka Peninsula around 11:25 a.m. local time Wednesday. It was originally estimated to have an 8.0 magnitude, but was later bumped up to an 8.8 magnitude. It was the biggest earthquake in the region in over 70 years.

Videos shared on social media showed the earthquake shaking Russian homes and damaging buildings, and photos taken in the aftermath showed large fissures in the soil.

A Kremlin spokesperson said there were “no casualties” following the natural disaster.

The earthquake was tied for sixth on the list of the strongest earthquakes ever recorded globally and is the largest since a 9.0 earthquake hit Japan, where the Fukushima nuclear power plant malfunctioned in 2011. Current workers at the Japanese nuclear site were evacuated before the latest tsunamis hit.

Among the six strongest earthquakes recorded was a 9.0 magnitude one that hit the Kamchatka Peninsula in 1952.

The Kamchatka region is particularly susceptible to earthquakes and tremors, given its location above the area where the Pacific tectonic plate slides underneath the North American plate in a process called subduction. Experts refer to this fault line as a megathrust fault, which can create some of the most powerful earthquakes.

Where did the tsunamis travel?

The resulting tsunamis first hit Russia’s Severo-Kurilsk District and eventually traveled to Japan, where 2 million people were told to evacuate.

The waves have since reached the coasts of Alaska, Hawaii, California, Oregon, and Washington. However, compared to Russia or Japan, the effects weren’t as damaging.

Hawaii recorded waves up to 5.7 feet high, while the highest recorded waves in Japan were 4.3 feet. Up to 10-foot high waves were expected across different areas in the Pacific.

What warnings have been sent out?

After the earthquake, a mix of tsunami warnings and advisories were issued.

Hawaii initially issued a warning before downgrading it to an advisory. The less severe forecast came as Pacific Tsunami Warning Center Director Chip McCreery said the “worst part” of the tsunamis was over for the state. Still, residents were instructed to seek higher ground as authorities continued to monitor conditions.

As of Wednesday morning, a tsunami warning remained in effect for part of the northern California coast. Meanwhile, tsunami advisories are still in effect for the rest of the West Coast, Hawaii, parts of the Alaskan coastline, and Canada’s British Columbia.

Japan lifted all of its tsunami warnings on Wednesday but retained its tsunami advisories for most of the country, from Hokkaido to Okinawa.

However, Chile upgraded its warning to the highest level and started evacuating hundreds of people. Tsunami waves could hit Peru and Chile in South America on Wednesday, but warnings and advisories were canceled for the Philippines, Guam, and the Northern Mariana Islands.

What has been the federal response?

No major disaster relief aid has been announced, but the U.S. Tsunami Warning System is actively monitoring the tsunamis as the situation develops.

President Donald Trump posted a message on social media Tuesday night, warning of tsunamis possibly reaching Hawaii and other states on the West Coast.

“Due to a massive earthquake that occurred in the Pacific Ocean, a Tsunami Warning is in effect for those living in Hawaii,” Trump wrote. “A Tsunami Watch is in effect for Alaska and the Pacific Coast of the United States. Japan is also in the way. Please visit tsunami.gov for the latest information. STAY STRONG AND STAY SAFE!”

On Wednesday morning, Homeland Security Secretary Kristi Noem said she spoke to Gov. Josh Green (D-HI) and that the state lifted its evacuation order for its coastal inundation zones. Nonetheless, Noem warned Hawaiians to exercise caution and stay safe.

“Please be careful when returning and watch out for damage,” Noem wrote. “We will continue to monitor in Hawaii, Alaska, and California.”
