An arm of Jason (top right), a remotely operated vehicle (ROV), takes samples of NW Rota-1 during an April 2009 expedition.

The ROV can get close to the eruptive vent because water pressure at 1,700 feet (520 meters) suppresses some of the volcano's explosive energy, said project chief investigator Bill Chadwick, an Oregon State University volcanologist.

Some of the most "intriguing observations" during the expedition came from the volcano pushing lava up and out, Chadwick said in a statement. " … The ground in front of us shuddered and quaked, and huge blocks were bulldozed out of the way to make room for new lava."
