Mega earthquake likely to strike Fukushima area within next few decades

What Is the Probability of a Mega-quake Striking Japan in the Future?, NHK News, 2 July 18,  “…….. A government panel has released its latest earthquake probability map, which indicates the likelihood of each area being hit in the coming 3 decades by tremors of 6-minus or above on the Japanese intensity scale of zero to 7 — about the same level as the one that hit Osaka. A member of the panel says an earthquake of 6-minus could strike anywhere in Japan, and urges people to be prepared.


High probability in the Kanto region and along the Pacific coast………. In the Kanto region, the probability of a major quake is highest in Chiba City, at 85 percent. The figure is 82 percent for Yokohama and 81 percent for Mito. Tokyo’s Shinjuku Ward is located in an area with 48 percent probability.

In the Tokai region, the probability for Shizuoka is 70 percent and Nagoya is 46 percent.

Beware of massive earthquakes that occur in ocean trenches The panel explains that these areas have high probabilities because massive earthquakes centering in the Chishima Trench, Japan Trench and the Nankai Trough have been occurring at intervals of a few decades to a century.

These earthquakes occur around ocean trenches where the oceanic plate is forced underneath the continental plate.

Huge earthquakes have been occurring especially around the Nankai Trough roughly every 100 years. As the last one took place more than 70 years ago, there is a growing probability the next one will happen soon around the Pacific coast of western Japan……….https://www3.nhk.or.jp/nhkworld/nhknewsline/backstories/megaquakestriking/
