Alaskan island triples in size in volcanic "hurricane"
According to researchers, Bogslof Island (also known as Agasagook Island) in the Bering Sea has tripled in size following over 36 eruptions in the past four months. The island forms the tip of an underwater stratovolcano and is one of the most active volcanos in the region, frequently blasting ash into the air as high as 20,000 feet.
The island grew as pyroclastic flows deposited tons of rock in the surrounding ocean. These flows are considered some of the most dangerous volcanic events, creating a hurricane-like cloud of ash and rock. However, there are no residents on this remote island, and the frequent eruptions have only caused delays in local air traffic posing no additional concern. The island is part of a wildlife refuge.
Bogoslof Island was first observed following an eruption in 1796. Since then, the area of the island regularly it expands and contracts. The volcano has two primary domes, named Fire Island and Castle Island along with many additional vents. Despite the frequent activity, many animals use the island as a refuge including birds and sea lions.
