La Palma, Canary Islands- 700+ Earthquakes Since July, 2011
This little tropical island off the coast of Africa holds the potential to wipe most of the U.S. Eastern Seaboard off the map. Active volcano ‘El Hierro’ runs down the southern half of La Palma, bisecting it, and creating a “Crescent Moon” shape facing Northwest.
Geologists have investigated this and found it is the beginning of a massive landslide that will occur at some point in our future. It has happened in the past, about 60,000 years ago.
Before this year, it looked like it could be another 60,000 years before the next slide. But since July 16, 2011, the Canary Islands Government has said it is monitoring an earthquake swarm, referring to the swarm as “the significant increase in seismic activity”.

On Friday, the Ministry of Economy, Finance and Government Security Canary convened the first ever meeting of the Steering Committee and Volcanic Monitoring, reflected in the Specific Plan Protection Civil and Emergency for Volcanic Risk, given what it described “the significant increase in seismic activity”.
“According to data provided by the seismic monitoring station IGN’s located in Valverde, one can conclude that from the noon on July 17 there has been a significant increase of low magnitude seismic activity in the municipality of Border of the island of El Hierro. To improve the location of this activity, has deployed a seismic network densification operational since July 21 has helped increase the number of earthquakes located, and can be viewed here“, the statement added.
The volcanic activity, principally at the convergence of the three ridges, resulted in the continual expansion of the island. A mere 50,000 years ago, as a result of seismic tremors which produced massive landslides, a giant piece of the island cracked off, crashed down into the ocean and scattered along the seabed.
According to ElHierro.com: “Although over 200 years have elapsed since the last eruption, El Hierro has the largest number of volcanoes in the Canaries with over 500 open sky cones, another 300 covered by the most recent outflows, and some 70 caves and volcanic galleries, notably the Don Justo cave whose collection of channels surpasses 6km in length.”
