Japan issued tsunami alerts and told people to evacuate seaside areas after a series of strong quakes on its western coastline Monday.
The Japan Meterological Agency reported quakes off the coast of Ishikawa and nearby prefectures shortly after 4p., one of them with a preliminary magnitude of 7.6.
It issued a major tsunami warning for Ishikawa and lower-level tsunami warnings or advisories for the rest of the western coast of Japan's main island of Honshu.
Japanese public broadcaster NHK TV warned torrents of water could reach as high as 5 meters (16.5 feet) and urged people to flee to high land or the top of a nearby building as quickly as possible.
Aftershocks felt
NHK said the tsunami waves could keep returning, and warnings were continuing to be aired more than two hours after the initial alert. Several aftershocks also rocked the region.
Government spokesman Yoshimasa Hayashi told reporters that nuclear plants in the area had not reported any irregularities. But he said it was critical for people in coastal areas to get away from the oncoming tsunami.
“Every minute counts. Please evacuate to a safe area immediately,” he said.
A tsunami of about 3 meters (about 10 feet) high was expected to hit Niigata and other prefectures on the western coast of Japan. Smaller tsunami waves were already confirmed to have reached the coastline, according to NHK.
Smoke spewing
The earthquakes themselves also caused damage. Japanese news footage showed reddish smoke spewing from an area in Wajima city, Ishikawa Prefecture, noting there could be a fire there. Details were not immediately available.
A house had crumbled in another area, and a search was underway to see if people were trapped in the rubble.
Bullet trains in the area were halted. Parts of the highway were also closed, and water pipes had burst, according to NHK.
Japanese media reports showed a crowd of people, including a woman with a baby on her back, standing by huge cracks that had ripped through the pavement.
More earthquakes
The Meteorological Agency said in a nationally broadcast news conference that more major quakes could hit the area over the next week, especially in the next two or three days.
Tsunami warnings were also issued for Japan's northernmost main island of Hokkaido and for parts of North Korea and Russia. Russian officials issued a tsunami alert for the island of Sakhalin, warning that areas across the island’s west coast could be affected by the waves.
In nearby South Korea, the weather agency urged residents in some eastern coastal towns to watch for possible changes in sea levels. Tsunami waves that hit later later can be bigger than the initial ones.
The Japanese government has set up a special emergency center to gather information on the quakes and tsunami and relay them speedily to residents to ensure safety, Prime Minister Fumio Kishida told reporters.
He reiterated the warning for immediate evacuation in affected areas.
Japan is an extremely quake-prone nation. In March 2011, a major quake and tsunami caused meltdowns at a nuclear plant.
