The region is having a real shaking. These two are the strongest, but some 60 quakes have been recorded in the area in 24 hrs.

I see there has also been a couple more large quakes In Lombok. There has been a very high level of seismic activity in this region for a number of weeks now. Today’s two largest quakes have been reported as 6.4 and 6.9 magnitude.

A quake of around 5.0 or more every couple of hours, literally

Evening all.

I see there was a good quake in NE of South America yesterday - Venezuela and some Caribbean islands. See:

As if Venezuela didn't have enough to worry about.

 

A week for the V's - Vanuatu also having magnitude 6+ quakes

I lived on Ambae in the '70s and the doors in the house often popped open unexpectedly with the quakes! Spooky.

Agreed. Not only must it be terrifying but it also makes you realise how powerless we are against things like tsunamis (and indeed to an extent earthquakes).

Why wasn’t the tsunami warning system not in place for this terrible tragedy?

Keep up. It was in place but the authorities cancelled it after an hour because a tsunami hadn't arrived. Then it did.

This is an absolute tragedy and shows just how our cosy little lives can be wiped out in seconds.

As Doc says, we are powerless. We may think we rule the world, but we dont.

Much like the Boxing Day 2004 tsunami this was quite harrowing to watch. Dreadful scenes and like you say Mother Nature cannot be stopped.

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?

I think you’re correct that melting permafrost will change the effects of earthquakes.  But in this case apparently it was the proximity to Anchorage and the shallow location that combined to cause so much damage.  The guy in the TV studio said it just arrived suddenly with a loud crack, rather than the more usual gradual onset.
