Today at 13:28 UTC there was an ML3.3 earthquake in Tenerife volcano. The depth of this earthquake was at 31 km depth. But I do not know if this earthquake was felt, so far nothing suggests it. But this is was just an minor earthquake on the earthquake scale.

It is normal for volcanoes to earthquakes at times, even when they are dormant. So I do not believe this earthquake means anything special for the Tenerife volcano. More details on this earthquakes can be found on EMSC web site here.
Jon, the EQ seems to have occurred on or near a small ridge from the maps you posted above.
This might be undersea eruption ridges from past eruptions. They are common in this type of area.
From what I have read on the AVCAN page on facebook, very few people actually felt it. Also, I’m not so sure this one is entirely volcano-related, there seems to be a fault line there. I’m still looking for a good map that covers all the known fault line and geologically active zones in North West Africa (Algeria, Morocco, Canarian Islands).
