CBS TV piece here:
Looks like a lot of damage.
The melt of the permafrost layer will make previously 'solid' structures now less so? Liquefaction of such areas could end up messing with lots of their infrastructure that , in past quakes, survived pretty much unscathed?
Then there are the continental shelf clathrate deposits?
If the Pacificication of West Beaufort is bringing warmer,saltier water in contact with the reserves then they may be less 'stable' than in previous times?
