Copahue volcano, quiet at the surface, today (SERNAGEOMIN webcam)
Copahue (Chile/Argentina): SERNAGEOMIN raised the alert level of the volcano to orange yesterday after an increase in seismic activity. A pulse of volcanic tremor was detected that could indicate magma moving into the volcano's plumbing system.
On the surface, no unusual activity has been seen at the volcano so far, except that an increase in SO2 emissions (approx 2,300 tons / day) was measured. This supports the idea that magma has risen under the edifice.

Current seismic signal at CRST station in La Restinga (IGN)
El Hierro (Canary Islands, Spain): (17 Mar) 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. ... Lees alle
