the island. A period of quiet followed, with another period of earthquake swarms starting on 14 June. Plotting of the earthquake epicentres showed that the magma was moving southwestwards across the central part of the island and under the area of the sea near the El Julan – La Dehesa area of the island, i.e. to the northwest of the submarine vent of 2011–2012. Deformation of the island continued at a faster rate than that observed prior to the October 2011 eruption. Sensors measured that inflation of height had taken place in the three days up to 27 June - a very fast rate of deformation. September 2012 activity In mid-September 2012 earthquake activity increased again. Source of the magma For the October 2011–March 2012 eruption, and the two phases of subsequent earthquake activity, plotting has shown that in all cases the magma rose under the area of Tanganasoga. In the eruption it worked south-eastwards to near La Restinga; in the February upsurge in activity followed the same path. Modelling of ground deformation measured with radar interferometry confirmed two shallow magma reservoirs, consistent with the migration of earthquakes epicenters. The June 2012 earthquake activity had the magma moving to the west of the island, and the current (mid-September) earthquake activity has shown that the magma moving south from Tanganasoga. Naming of the volcano In 2016, the underwater volcano was officially named Tagoro. The word comes from the Guanche language and means 'circular enclosure made of stones' or 'meeting place'. The name was suggested by the Instituto Español de Oceanografía (Spanish Oceanography Institute) to the Instituto Hidrográfico de la Marina (Navy Hydrography Institute), which is in charge of the naming of such geographical features.
