Tohoku tsunami impacted home-building habits of eco-engineer heart urchins
In a new study published in the Journal of Geophysical Research: Oceans, a journal of the American Geophysical Union, researchers explore how tsunamis impact shallow marine environments, also known as benthic environments, and the small, burrowing animals that dwell there.

New study challenges long-held tsunami formation theory (plus video)
A new study is challenging a long-held theory that tsunamis form and acquire their energy mostly from vertical movement of the seafloor. The finding validates an approach developed by researchers that uses GPS technology to detect a tsunami’s size and strength for early warnings.

New study shows how impacts generated Martian tsunamis
A study published last year interpreted images of the red planet and suggested the deposits were made by impact-generated tsunamis more than 3 billion years ago. In a new study, Costard and his colleagues independently build on that work by including the geological characteristics of the deposits and modeling how impact-generated tsunamis could have created them. They conclude the deposits may have come from asteroids slamming into a northern ocean billions of years ago, generating waves 300 meters (nearly 1,000 feet) high.

Deposits discovered in Monterey Canyon’s mouth may cause marine landslides, study finds
Researchers have discovered a large concentration of sediment deposits at the end of Monterey Canyon, an underwater chasm beneath Monterey Bay, California. The sediment deposits are relatively young and may be more likely to catalyze underwater landslides than other sections of the canyon, according to the researchers who presented their discovery at the 2016 American Geophysical Union Fall Meeting.

New research estimates probability of mega-earthquake in the Aleutians
A new study estimates the probability of a Magnitude 9+ earthquake in the Aleutian Islands—an event with sufficient power to create a mega-tsunami especially threatening to Hawai‘i. In the next 50 years, there is a 9 percent chance of such an event, according to researchers from University of Hawai‘i at Mānoa.
