Preliminary Results on the High-Resolution Seismic Survey at Puerto Foster Bay, Deception Island, Antarctica
A high-resolution seismic survey was conducted within Puerto Forster Bay, Deception Island, Antarctica, in order to study the seafloor geological characteristics. This bay was originally the volcano's crater and became a bay after part of the wall was destroyed allowing the sea water to come in...
