Scientists discover past climate change to blame for Antarctica's giant underwaterlandslides PlymUni NatureComms
, the scientists say these weak layers—made up of historic biological material—made the area susceptible to failure in the face of earthquakes and other seismic activity.
Through analyzing the effects of past underwater landslides, they say future seismic events off the coast of Antarctica might again pose a risk ofProfessor Rob McKay and Dr Jenny Gales examine the half-section of a core recovered from the Antarctic seabed.
