In the latest report prepared by a Japanese government earthquake task force, it was estimated that up to 298,000 people could be killed in a Nankai Trough megaquake with a magnitude of 8-9. The casualties would include 215,000 deaths caused by tsunami waves, the report said.
Aftershocks have been recorded for both earthquakes. On Dec. 8, Japanese authorities warned an even more powerful earthquake could strike within the next week and called on residents from the northernmost island of Hokkaido down to Chiba prefecture, east of Tokyo, to be on high alert.
