submarine landslides

The planet’s largest landslides happen on submarine volcanoes

Large volume submarine landslides, triggered by the inception and growth of submarine volcanoes, represent among the largest mass movements of sediment on Earth’s surface.

Study uncovers new evidence for assessing tsunami risk from very large volcanic island landslides

The risk posed by tsunami waves generated by Canary Island landslides may need to be re-evaluated, according to researchers at the National Oceanography Centre. Their findings suggest that these landslides result in smaller tsunami waves than previously thought by some authors, because of the processes involved.

Will sea level rise lead to more underwater landslides?

Underwater landslides are potentially very damaging: they can generate tsunami waves and destroy expensive and crucial seabed infrastructure, such as pipelines and cables.
