Minor earthquake just south of La Gomera

There was a minor earthquake of 1.9 on the Richter scale in the Atlantic about 25 kilometres off the south coast of La Gomera yesterday morning just after 2am local time (1am UTC).The event occurred in a depth of only one kilometre, and while this is a bit unusual minor quakes below the Atlantic seabed around the Canaries happen regularly and are considered normal.

The spectrogram of the seismic station on La Gomera for the time between 1-2 am UTC clearly shows the quake (left)
