tsunamis

As the 10th anniversary of the Indian Ocean tsunami approaches on Dec. 26, greatly expanded networks of seismic monitors and ocean buoys are on alert for the next killer wave.

Small islands boost the power of tsunami waves, rather than absorbing their impact, a new study shows.

A team of scientists ventured to the depths of the Caribbean Sea on a three-month voyage to study fault zones and strange biological communities.

The Caribbean usually conjures images of white sandy beaches and sparkling turquoise water, but beneath the sea's tranquil surface, powerful forces are at work.

A monster earthquake in Alaska could trigger 5-story-high tsunami waves that would inundate some of Hawaii's most iconic beaches and its critical power infrastructure, new research suggests.
