Study of the the Tenerife island (Canaries, Spain) unrest via geodetic observations
Abstract
After a quite period larger than 90 years from the last eruption, a significantly unusual seismic activity started in April 2004 on the volcanic island of Tenerife, Canary Islands, Spain. It marked the first observationally documented unrest in the island with more than 3000 seismic events in the following twenty two months. The geophysical signature of the reactivation includes felt earthquakes, gas emissions, surface displacements and gravity changes. Here we present the observed anomalies detected using geodetic observation (GPS and InSAR) of this unrest up to 2006, and their interpretation in order to shed light on the causative sub-surface processes for the unrest, its time and spatial evolution.
