It is considered that the 2011-2012 El Hierro eruption at La Restinga in the southernmost part of the island is a vent of Tanganasoga. Swift deformation of Tanganasoga was recorded during the October 2011-March 2012 eruptive phase of this volcanic activity, and in June 2012 a new phase was heralded by earthquakes and rapid deformation upwards and outwards of Tanganasoga, indicating the deep-seated movement of magma below.
