Volcanic activity in the sea off the Canary island of El Hierro, seen in this aerial photo taken on November 5, 2011. The regional government of the Canary Islands ordered the evacuation of homes and road closures near the southern tip of El Hierro after two earth tremors and increased offshore volcanic activity caused a buildup of malodorous debris floating on the sea. Seismic activity began in the area on July 17 and residents have since been rocked by more than 10,000 tremors, while underwater fissures have released an almost continuous flow of sulfurous gases, smoke and hot debris.
