El Hierro volcano update: New earthquake swarm

Location of earthquakes under El Hierro since yesterday
A new swarm of earthquakes started yesterday. So far, almost 200 tiny quakes (none above magnitude 3 so far) have occurred in a broad N-S oriented area beneath the NE part of the island at around 18 km depth.
A possible explanation includes a new magmatic intrusion at depth (magma accumulating at the lower crust-mantle boundary).
