2005 Volcanic activity
Volcanic unrest occurred at the volcano in January 2005. Carbon dioxide emissions rose from 75 to 354 tons per day, and hydrogen sulfide emissions rose from 35 to 152 tons per day. Seismic activity remained elevated under the volcano. Fumaroles increased in pressure, and emitted sounds. There was no significant ground deformation recorded.
Seismic activity increased at the volcano during April and May 2004. Over 200 earthquakes from magnitude 1 to 3 were recorded, with three being felt by residents. Most earthquake epicenters were centred around the NW rift zone of Tenerife and in the strait between Gran Canaria and Tenerife. The earthquake crisis was probably related to dike emplacement at 3-4 km depth.
