The National Geographic Institute (IGN) has confirmed to the direction of the Civil Protection Plan for Volcanic Risk Islands (Pevolca) that during the day of November 10, 46 earthquakes were located, one of them felt by the population, although its intensity has not yet been realized.

The largest of the events had a magnitude 3.5 on the Richter scale and intensity III was recorded at 18:31 hours NW of the town of Frontera, 3 kilometers from the coast at a depth of 21 kilometers.

The rest of the movements recorded were located mainly in the area of the Gulf, aligned NNW / SSE from the sea to the center of the island, forming two distinct groups: the first between 14 and 17 kilometers and the second between the 20 to 23 kilometers. In total, since the day July 17, 2011 11 445 events have been found.
