# 5482

 

 

Over the past 7 days there have been more than 240 earthquakes greater than 2.5 magnitude offshore of Honshu island.  


The 7.2 quake of three days ago is now being looked at as being a foreshock to the 8.9 massive event that occurred yesterday.   

 

Since that quake, dozens of heavy aftershocks have been recorded, along with a couple of hundred smaller (2.5 or greater) temblors. 

 

Additional heavy aftershocks are possible for months.

Aside from the considerable emotional toll these aftershocks must be taking on the residents and emergency responders, there is the very real danger of already damaged buildings collapsing in these new shocks. 


For those trapped in the rubble, and for their rescuers, these smaller quakes pose a serious risk of causing additional injury or even death.
