October 12th 14:30 event at El Hierro
Five geologist & scientists: @rschott @nchazarra @pabloj_gonzalez @Lumifg & @teideano from America and Spain talking about El Hierro the very same day the second? event toke place. Network thinking.
48 hrs & the volcanic tremor @ El Hierro is still going strong: t.co/g3jVhlY9 That's a lot of magma on the move. When will it emerge?- @nchazarra @Lumifg It seems remarkable that none of the quakes recorded in the last two days are shallower than 10km: t.co/0l9Jvj5h
@nchazarra @rschott perhaps the volcanic tremor is covering up the detection of any other shallower quake.
Abrupt decrease of tremor amplitude in El Hierro. I mean really abrupt!! t.co/mkjbU24Z- Given that prior to reduction, an increase in higher frequencies occurred. Explosive events couldn't discarded. t.co/mkjbU24Z
@pabloj_gonzalez Yeah, it's really a very abrupt change. Those higher frequencies could be from a great pressure release!- @nchazarra I think you may have hit the nail on the head. Not my area of expertise, but I like your explanation of abrupt frequency change.
- @nchazarra @rschott @pabloj_gonzalez I almost miss the gig. These changes are out of my league, not an expert.
- @pabloj_gonzalez Maybe no shallow magma chamber but magma still has to break conduit to the surface to erupt-no evidence it's done that yet.
- @nchazarra @pabloj_gonzalez @rschott therefore no shallow chamber and the tremor started when the magma moved upwards massively. Likely?
- @nchazarra @pabloj_gonzalez @rschott almost an hour and the tremor signal hasn't recovered its amplitude t.co/TqPdzDju
