6.7 magnitude earthquake hits northeast Japan, triggers tsunami warning of up to 1m

An earthquake has hit the northeast region of Japan on Dec. 12, triggering tsunami warnings.

The Japan Meteorological Agency reported that an earthquake with a preliminary magnitude of 6.7 struck the region at 11:44am off the coast of Aomori Prefecture.

The agency also issued a tsunami advisory for waves up to 1m.

The Singapore Embassy in Tokyo posted on Facebook, warning Singaporeans in affected areas to keep away from coasts and river mouths.

Singaporeans are also advised to continue to evacuate until all advisories are lifted.

Days apart

This comes just days after a magnitude 7.5 earthquake struck the same region on the evening of Dec. 8.

At least 30 people have reportedly been injured, and tsunami waves of up to 70cm were recorded.

Tsunami warnings have been downgraded as of Dec. 9 morning, but Japanese authorities have issued a precautionary alert for a megaquake of magnitude 8 or higher.

Japan’s government has warned that up to 199,000 people could die if a massive maximum-level earthquake triggers a major tsunami along the Japan and Chishima trenches, a threat experts say is growing more imminent, according to Japanese media.

A megaquake in the area could set off tsunamis impacting Japan’s Pacific coastline from Hokkaido down to Chiba Prefecture.

With harsh winter weather already setting in, authorities say preparations must be thorough.

The council stressed that fatalities could be reduced by 80 per cent if people are able to reach higher ground promptly.

Proper cold-weather preparation could also “virtually eliminate” hypothermia-related deaths.

Individuals are encouraged to keep cash and identification with them, double-check emergency supplies, and secure furniture in case aftershocks grow stronger, according to The Mainichi Shimbun.
