Current seismic signal at CRST station in La Restinga (IGN)
Current seismic spectrum and tremor amplitude (CRST station)
What looks like a new swarm of earthquakes accompanied by strong harmonic tremor appeared on the southernmost seismic station at La Restinga. If it is not due to some local, human-induced work or malfunction, it suggests that the quakes are very shallow, since they don't appear on the signals of other stations.
Depth vs time of earthquakes at El Hierro volcano during the past 30 days

A large earthquake of estimated magnitude 5.4 (USGS) occurred just minutes ago. USGS places the quake at 22.8 km depth NW of El Golfo, i.e. away from the area of the recent earthquake swarm and current inflation. ... [more]
El Hierro volcano (Canary Islands, Spain): strong inflation and tremor - possible precursors to a new eruption
Thursday, Dec 26, 2013
Although earthquakes have largely ceased for the moment, the island experiences ongoing rapid inflation and harmonic tremor, both signs that an eruption could be imminent. ... [more]
