A seismic swarm started under Cumbre Vieja volcano (La Palma) in the Canary Islands on Saturday, October 7, 2017. Authorities said they will increase monitoring the volcano starting October 10 and assign 5 scientists to keep track of the earthquakes. The last eruptive phase of this volcano started on October 26, 1971 and ended on November 18 (VEI 2).
The new, 24-hour monitoring network of the National Geographic Institute (IGN) has recorded a total of 68 earthquakes under the volcano since October 7 with magnitudes from 1.5 to 2.7 on the Richter scale.
The largest earthquake so far was M2.7 at 11:03 UTC on October 7 at a depth of 28 km (17.4 miles). The second largest was M2.6 at 23:23 UTC on October 7.

“This potential problem was first raised a few years ago when a crack appeared along the ridge peak of the island.
Now it has grown some and the swarm of earthquakes could easily dislodge the unstable western wall of the volcano causing it to slip into the ocean creating a mega tsunami, which would target Florida, Georgia, the Carolinas, NY etc as far as Nova Scotia.
