Thanks TA for this.
I had mainly my eyes on El Hierro and didn't check La Palma graphs prior to the start of the recent activity at El Hierro.
So from 3-5 we did have stuff going on at or around La Palma, not linked to any activity at El Hierro. It also looks quite Harmonic after the event on
the third at 18:00.
What I think happened there
Some magma has found a way to break through a "layer", that's what the activity at around 18:00 on the third seems to point out (small event that
wasn't even register as a quake) and from there on magma was on the rise up to the 5th. This also happened quite deep and I don't think there's any
reason to worry about for the moment.
I'm not sure about the 22nd activity although and if it has something to do with the activity from the 3-5.
You can also clearly see the two different kinds of activity with what's going actually on since a couple of days at El Hierro.
El Hierro quake swarms, probably from volcanic activity but still no Harmonic events meaning the magma isn't rising yet.
La Palma (3-5 March) event and a continue Harmonic activity between 0/2 -> 3/4 Hz. Typical volcanic HT's are in between 2 and 5Hz if I remember well
but on these graphs the show up form 0 -> 5.
