One of the strongest earthquakes ever recorded struck Russia’s sparsely populated Far East early Wednesday, causing tsunamis of up to four meters (12 feet) across the Pacific and sparking evacuations from Hawaii to Japan.

The magnitude 8.7 quake struck at 8:24 a.m. (2304 GMT Tuesday) off Petropavlovsk on Russia’s remote Kamchatka Peninsula and was one of the 10 biggest recorded, according to the United States Geological Survey (USGS).

Russian authorities said a tsunami hit and flooded the port town of Severo-Kurilsk, while local media said one of between three and four meters high was recorded in the Elizovsky district of Kamchatka.

A video posted on Russian social media appeared to show buildings in the town submerged in seawater. Authorities said the population of around 2,000 people was evacuated. Several people were injured in Russia by the quake, state media reported, but none of them seriously.

An Elizovsky resident told state media Zvezda, “The walls were shaking. It’s good that we packed a suitcase, there was one with water and clothes near the door. We quickly grabbed it and ran out… It was very scary.”

Officials from countries with a Pacific coastline in North and South America—including the United States, Mexico, and Ecuador—issued warnings to avoid affected beaches.

In Japan, people evacuated by car or on foot to higher ground—including in Hokkaido, where a first wave measuring 30 centimeters was observed. There were no injuries or damage reported in Japan as of midday (0300 GMT).

In Hawaii, Honolulu Mayor Rick Blangiardi said residents and the thousands of visitors should get to safety on upper floors of buildings or higher ground.

Governor Josh Green said, “People should not, and I will say it one more time, should not, as we have seen in the past, stay around the shoreline or risk their lives just to see what a tsunami looks like. It is not a regular wave. It will actually kill you if you get hit by a tsunami.”

Pacific warnings

Wednesday’s quake was the strongest since 1952 in the Kamchatka region, the regional seismic monitoring service said, warning of aftershocks of up to 7.5 in magnitude.

The epicenter of the earthquake is roughly the same as the massive 9.0 tremor that year which resulted in a destructive, Pacific-wide tsunami, according to the USGS. At least six aftershocks have further rattled the region, including one of 6.9 magnitude and another listed at 6.3.

The U.S. Tsunami Warning Centers said waves exceeding three meters above the tide level were possible along some coasts of Ecuador, northwestern Hawaiian islands, and Russia.

Between one- and three-meter waves were possible along some coasts of Chile, Costa Rica, French Polynesia, Guam, Hawaii, Japan, and other islands and island groups in the Pacific, it said.

Waves of up to one meter were possible elsewhere, including Australia, Colombia, Mexico, New Zealand, Tonga, and Taiwan. It described the potential conditions as “hazardous.”

At Inage Beach in Chiba prefecture in Japan, a security perimeter was set up, and a rescue worker told AFP that the seaside area was off limits until further notice.

Canadian tourist Leana Lussier, 17, told AFP, “I didn’t expect there to be a tsunami; I actually made a joke about it when we heard (the alert).” 

Local Tomoyo Fujita, 35, told AFP as she left the area with her young daughter, “We came here hoping to swim, but once we heard a tsunami warning had been issued, we didn’t go in at all, not even close to the water.” 

Television footage showed several whales washed up on a beach. Workers at the stricken Fukushima nuclear plant in northeast Japan—destroyed by a huge quake and tsunami in 2011—were evacuated, its operator said.

Aftershocks

Tsunami alerts were pushed to mobile phones in California, according to local AFP reporters.

U.S. President Donald Trump said on social media, “STAY STRONG AND STAY SAFE!” 

Tsunami sirens blared near Hawaii’s popular Waikiki surf beach, where an AFP photographer observed gridlocked traffic as Hawaiians escaped to higher ground.

The U.S. Tsunami Warning Centers issued a Tsunami Warning—its highest level alert—for the entire U.S. state of Hawaii, with the first waves expected at 7:17 p.m. local time (0517 GMT).

The seismology center said in a warning, “People are also advised to stay away from the beach and not to go to the coast.” 

Vessels were ordered to head to open water ahead of the expected arrival of waves up to 2 meters, while government employees in Honolulu were sent home early.

Meanwhile, authorities in Russia’s far eastern Sakhalin region declared on Wednesday a state of emergency in the northern Kuril Islands, where tsunami waves have damaged buildings and caused flooding.

“A state of emergency has been declared in the North Kuril District, where an earthquake and tsunami occurred today,” the Sakhalin government said in a statement.
