Array analyses of volcanic earthquakes and tremor recorded at Las Cañadas caldera (Tenerife Island, Spain) during the 2004 seismic activation of Teide volcano

On the detectability of Teide volcano magma chambers (Tenerife, Canary Islands) with magnetotelluric data

“…Most studies agree on locating the reservoir associated with mafic basaltic in the northern part of the island, at depths between 5 and 14 km b.s.l (Araña et al 2000;Almendros et al 2007;Blanco-Montenegro 2011). The seismic tomography study mentioned above (De Barros et al 2012) also detected a second structure probably associated with a mafic reservoir.…”

Shallow structure beneath the Central Volcanic Complex of Tenerife from new gravity data: Implications for its evolution and recent reactivation

“…Details on investigation strategies and results can be found in the recent papers by Gottsmann et al (2006), Almendros et al (2007), Fernández et al (2007, and Martí et al (2008a). Two features are worth highlighting.…”

“…The Central Volcanic Complex (CVC) of Tenerife (Canary Islands, Spain)), which includes the 16 x 9 km wide Las Cañadas caldera (LCC, Figure 1), reactivated after an almost century-long period of quiescence in spring 2004, with increased seismicity (including felt earthquakes) and subsurface mass addition into its north-western and western portions Tárraga et al, 2006;Gottsmann et al, 2006;Almendros et al, 2007). It has been speculated that earthquake locations and density changes during the reactivation may be controlled by the internal structure of the CVC (Martí et al, 2008a).…”

“…It is the responsibility of scientists and authorities to prevent false alarms, unnecessary public distress, economic losses, and the discredit of science. J. C. Carracedo Many seismic, geochemical, hydrological, and microgravity signatures support Tenerife's recent volcanic unrest [Pérez et al, 2004;Marrero et al, 2005;Almendros et al, 2007;Gottsmann et al, 2006;López et al, 2006;Tarraga et al, 2006;Pérez et al, 2007]. Volcanic unrest at Tenerife may or may not affect Teide's shallow magmatic system and therefore prompt its reawakening.…”
