Well, I have no idea what is going on here. There was an M7.4 and I don't know the relationship of the fault area. Nevertheless, the earthquakes are getting bigger, when normal aftershocks get smaller.
It is more dangerous if we see the aftershock zone of this earthquake creep up towards the crotch.
So, we have to wait. This is a very clean subduction zone. That means it gets an M9+ every few hundred years. But it can't do a Brazilian right up to the tip. It has to go down the other side. That's when we have a super-tsunami. However, we are still at 1 in 100, and that gets cut down with every larger earthquake. How long can you tread water? I'm glad that trumpy has cut all geophysics, this is scary.
ps this is a 'shaped charge' for a tsunami. The good path is that all this settles down in a normal aftershock sequence. The recent earthquake isn't that much bigger than the first one, so if there are no more, then everything is happy-happy.
