[VOLCANO] Earthquake activity below El Hierro volcano, Canary Islands, Spain

Recently El Hierro volcano of the Canary Islands has been experiencing a seismic swarm beneath it, which as of yesterday reached to over 700 events.

Most of these events have been at Magnitudes of around 2 (+/-0.5) and are clustered beneath El Hierro whilst the depths of these earthquakes have been roughly between 9 and 16 km for the most part, with the exception of a few shallower and deeper quakes, the shallowest of which has been 4 km.
If we look at these earthquakes in two plots here [link to www.volcano-blog.com] we can see the clustering of these earthquakes is mainly confined to an oval area at 10 km depth.

El Hierro is a broadly basaltic volcano which might have been active in 1793 although this is uncertain.
