Over 20-odd years ago I remember reading that based on past anniversaries, that an earthquake in Tokyo was overdue.
The main context was Japan’s readiness and the affects of such an earthquake on the global capital markets when Japanese Insurance companies would liquidate many $billions of liquid assets to rebuild - as although Tokyo had been building ‘earthquake proof’ building during the decades before, due to technological advances, some were more earthquake proof than others.
So at all times I get very nervous when I hear of seismic activity in the region; isitmebut recently they seems more frequent and destructive than usual e.g. Nepal?
When I read a headline like the link below, I’m not just concerned for the citizens of Tokyo due to potential Tsunamis we recently witnessed, it’s the potential structural damage, the like we have not seen before in modern times - when they say the only potentially safe place is the surrounding grounds of the Emperors Palace, built on very solid rock.
