A disaster of unimaginable scale looms over Japan as its government is warning that the next ‘megaquake’ could kill as many as 300,000 people. Such a seismic monster – which could trigger a tsunami powerful enough to obliterate entire coastal regions off the Pacific coast – has been feared for a long time.

A possible magnitude-nine earthquake along the Nankai Trough, a submarine trough near the South of Japan, may lead to up to 298,000 deaths and a loss of up to 270 trillion yen (S$2.43 trillion) in Japan's economy.

There is a reason why California chooses the last week in March to focus on tsunamis. It marks our worst historic tsunami disaster.

As California officially observes Tsunami Preparedness Week this week, one of the most vulnerable communities in the state is located on the Central Coast.

The latest report revises the anticipated death toll from a Nankai Trough megaquake to approximately 298,000, down from a previous estimate of 323,000 made a decade ago. This adjustment considers a scenario where the disaster strikes during a winter night,

Retirement is coming for more baby boomers. Here's how this growing trend will impact economies and industries.

Cornell-led researchers drilled 7 km deep into the Japan Trench to study the fault behind the 2011 Tohoku earthquake, uncovering key insights into earthquake mechanics and tsunami risks. A team of international marine researchers,

A magnitude 6.8 earthquake that rocked the bottom of the South Island struck in a seismic environment poorly understood by scientists – but which poses a major tsunami hazard. The 2.43pm quake hit about 167km west of Rakiura/Stewart Island.
