Minor earthquake felt in La Gomera

A minor earth tremor averaging 2.8 on the Richter scale occurred at a depth of only eight kilometres in the Atlantic very close to La Gomera's west-north-western coast at around 11:10 pm late Tuesday night, January 22nd 2019

This is nothing to worry about, as La Gomera's former volcanoes are long extinct and the island has not experienced any volcanic activity for far more than a million years, being one of the oldest islands in the Canaries. La Gomera existed long before the volcanically very active neighbouring island of El Hierro was even born. However, the abundant seismic activity in and around the Canary Islands rarely comes as close and in such shallow depth as Tuesday night's minor earth tremor.

Generally volcanic activity in the Canaries is of a 'mild nature', but magma movements deep under and around the Canary Islands cause regular tremors. It is however a rare occurrence that such a quake is registered by the seismic station situated in the mountains of the national park with an epicentre so close to La Gomera, and last night's tremors were felt by the population in La Gomera's sparsely populated west and north, see the pointers in the map above, which the show locations of verified reports published by the Spanish National Geographic Institute (IGN). This quake also registered at all seismic stations in neighbouring islands, with the peak value 3.9 having been recorded at the station in La Gomera (EGOM)  a few seconds before 23:10h, at the start of the tremor.

The last minor quake recorded close to La Gomera was recorded in September 2017, see previous post...
