its not finished by a long shot I have been watching it in an amateur fashion.

The dyke is not extending and is now outside the ice field and has stopped propagating forwards but is still working down and left and right. They use a thing called harmonics to see how much larva is moving and there is loads of it moving fast.

The main volcano crater has 700meters of ice sitting on top of it. But they can see that the chamber under it is still filling and pressurising. The 5.7 quake is the largest quake since 2008.

If it does go bang which some seem to think it is just a matter of time is going to be big.

If the dyke works its way to the surface and goes first it may stop the under ice sheet eruption happening but it may cause the crater to collapse.

All very interesting from 1000's of nautical miles away.
