5.4 magnitude earthquake shakes Canary Islands: one of the largest tremors ever
December 27, 2013 – CANARY ISLANDS – Something is going on under El Hierro, and recent events suggest this time things could be dramatically different. Two years after a new underwater volcano appeared offshore of El Hierro in the Canary Islands, earthquake swarms and a sudden change in height suggest a new eruption is brewing near the island’s villages, officials announced today (Dec. 27). After the announcement, one of the largest temblors ever recorded at the volcanic island, a magnitude-5.4 earthquake, struck offshore of El Hierro at 12:46 p.m. ET (5:46 p.m. local time) today, the National Geographic Institute reported. Residents on the island reported strong shaking, and the quake was felt throughout the Canary Islands, according to news reports. The earthquake’s epicenter was 13 miles (22 kilometers) deep. Before the earthquake struck early this afternoon, the island’s volcano monitoring agency, Pelvolca, had raised the volcanic eruption risk for El Hierro to “yellow.” This warning means that activity is increasing at the volcano, but no eruption is imminent. A similar burst of activity prompted a yellow warning in June 2012, but the volcano soon quieted down. –TEP, LS

Meanwhile, scientific research is predicting that an eruption of the Cumbre Vieja volcano, at La Palma in the Canary Islands would result in a massive mega-tsunami that would reach the East Coast of America.
Geological evidence suggests that during a future eruption, Cumbre Vieja Volcano on the Island of La Palma may experience a catastrophic failure of its west flank, dropping 150 to 500 km3 of rock into the sea. Using a geologically reasonable estimate of landslide motion, we model tsunami waves produced by such a collapse. Waves generated by the run-out of a 500 km3 (150 km3) slide block at 100 m/s could transit the entire Atlantic Basin and arrive on the coasts of the Americas:
