Tsunami warning issued for Hawaii after 8.7 earthquake near Russia02:04
A powerful 8.8 magnitude earthquake hit near Russia’s Kamchatka Peninsula, prompting Japan’s meteorological agency to issue a tsunami alert and the National Weather Service to issue a tsunami warning for the state of Hawaii and parts of Alaska on Wednesday.
A tsunami advisory was also issued for parts of Alaska and the entire West Coast, stretching from the California-Mexico border up to the Alaska-British Columbia border.
Japan’s meteorological agency said the quake occurred at 8:25 a.m. local time on Wednesday and registered a preliminary magnitude of 8.0, later adjusted by the U.S. Geological Survey to 8.8.

The Japan Meteorological Agency said a first tsunami wave of about 30 centimeters, or approximately 1 foot, reached Nemuro on the eastern coast of Hokkaido.
Damage and evacuations were reported in the Russian regions nearest the quake’s epicenter on the Kamchatka Peninsula. The first tsunami wave hit the coastal area of Severo-Kurilsk, the main settlement on Russia’s Kuril Islands in the Pacific, according to the local governor Valery Limarenko. He said residents were safe and staying on high ground until the threat of a repeat wave was gone.
The Pacific Tsunami Warning Center said waves of 1 to 3 meters, or about 3 to 10 feet, above tide level were possible along some coastal areas of Hawaii, Chile, Japan and the Solomon Islands. Waves of more than 3 meters were possible along some coastal areas of Russia and Ecuador.
Tsunami warning sirens blared Tuesday in Honolulu and people moved to higher ground.
“A tsunami has been generated that could cause damage along coastlines of all islands in the state of Hawaii. Urgent action should be taken to protect lives and property,” the National Weather Service said in an alert. The arrival of the first wave was predicted at around 7:17 p.m. local time, or about 1:17 a.m. ET.
“The danger can continue for many hours after an initial wave as subsequent waves arrive,” NWS said. “Tsunami heights cannot be predicted and the first wave may not be the largest. Tsunami waves efficiently wrap around islands. All shores are at risk no matter which direction they face.”
The U.S. Geological Survey said the earthquake hit at a depth of 19.3 kilometers, or about 12 miles.
In response to the tsunami warnings, President Trump wrote in a social media post Tuesday night to “STAY STRONG AND STAY SAFE!”
The quake was about 160 miles away from Hokkaido, Japan’s northernmost of the country’s four big islands, and was felt only slightly, according to Japan’s NHK television.
Russia’s TASS news agency reported from the biggest city near the epicenter, Petropavlovsk-Kamchatsky, that many people ran out into the street without shoes or outerwear. Cabinets toppled inside homes, mirrors were broken, cars swayed in the street and balconies on buildings shook noticeably.
TASS reported power outages and mobile phone service failures in the capital of the Kamchatka region. The news agency also quoted a local Russian official as saying residents on Sakhalin Island were being evacuated and emergency services were working at full capacity.

The earthquake appeared to be the strongest anywhere in the world since the March 2011 earthquake off northeast Japan that measured 9.0 magnitude and caused a massive tsunami that set off meltdowns at a Fukushima nuclear power plant. Only a few stronger earthquakes have ever been measured around the world.
New Zealand authorities issued warnings of “strong and unusual currents and unpredictable surges” along coastlines throughout the country. The alert by the government emergency management agency said people should move out of the water, off beaches and shore areas, and away from harbors, marinas, rivers and estuaries. New Zealand is in the South Pacific and about 6,000 miles from the epicenter.
Over a week ago, five powerful quakes — the largest with a magnitude of 7.4 — struck Russia’s Kamchatka Peninsula. And earlier this month, a tsunami advisory for Alaska’s southern peninsula was issued after a major earthquake with a preliminary magnitude of 7.3 hit the Aleutian Islands area.
On Nov. 4, 1952, a magnitude 9.0 quake in Kamchatka caused damage but no reported deaths despite setting off 9.1-meter (30-foot) waves in Hawaii.
How are tsunami levels categorized?
There are four levels of tsunami alerts: warning, advisory, watch and information statement, according to the National Weather Service. A tsunami warning is the most severe alert, meaning residents should take action due to a tsunami that may cause widespread flooding.
A tsunami advisory has the potential for “strong currents or waves dangerous to those in or very near the water,” according to the NWS. A tsunami watch advises those to be prepared because a distant earthquake has occurred and a tsunami is possible.
The lowest level of alert is a tsunami information statement from the NWS, which advises those to “relax” since an earthquake has occurred, but there is no threat or it was very far away.
