Abstract

Gravity changes observed around Teide (Tenerife) between May 2004 and July 2005, due to the suspected reawakening of the volcano, are reinterpreted here. Our objective is to seek multiple sources of the observed gravity signal. Our interpretation is based on the decomposition of the gravity signal into shallow and deep fields, and subsequent inversion of each field by means of 3D line segments. The shallow (near-surface) segments are interpreted as hydrothermal fluids. A short deep segment at the depth of about 6 km is interpreted magma injection. Our inversion results seem to be in fair agreement with the model of magma intrusion proposed by Cardeña et al. (Journal of Volcanology and Geothermal Research, 206:15, 2011).
