In the ocean just south of La Restinga, Canary Islands, the submarine volcano of El Hierro continued its eruptions this year, building, and spewing volcanic material into the ocean above. By late February 2012 the depth of the highest point of the volcano was 100m below sea level. (NASA Earth Observatory/Jesse Allen, Robert Simmon) # |
