– Thanks to ER readers Colin, Tommy, Chris and Vinch77 who have alerted us we can bring you this “breaking News”. A very strong seismic event has started at El Hierro. Check the HT graph and volcanic earthquakes list below (in a time-frame of only 10 minutes, 9 volcanic earthquakes have been listed by IGN + more to come) :

– The M3.8 earthquake which occurred yesterday to the North of Tenerife is a pure tectonic event as the hypocenter was reported at 51 km. There are more moderate tectonic earthquakes to the north of Tenerife.
– A small volcanic earthquake swarm occurred around midnight yesterday. Most of the epicenter below the central crater area of the island. No HT generated during that period. The strongest earthquakes are however visible on the CHIE graph

– A short period of seismic activity near midnight earlier today.

– The so called activity which started around 08:00 this morning ended at 18:00 UTC this evening. The same occurred yesterday. The logical explanation for this is human interference. Seismographs are very sensitive instruments and cars, people or other human activities can influence the recordings. We think this is the case here.
