Ah this probably explains events @ Kasatochi a bit later.

It showed up on the NEIC as a large number of small events.

Looks like it squeezed a magma filled fracture into the volcano.

The footprint diagram should reveal a segment boundary trans comp series & a 2nd set around nearby Kasatochi vol. where the magma went up the high level pipe fracture.

Apparently produced pyro flows, awaiting photos with interest.

have a nice day: Ag
