In subduction zones, the greatest hazard from earthquakes often comes from tsunami waves. However, models linking earthquake slip to tsunamis often fit data poorly (e.g.

The marine geophysical data collected during the 2015 MEGA-TERA expedition provide a unique window into the near-trench structure of the Sumatran accretionary wedge.

The Mentawai Gap — Tsunami Earthquake Risk Assessment (MEGA-TERA) project is a scientific expedition that aims to investigate the cause of tsunamis in the seismically active zone west of Siberut Is

The Mentawai Gap–Tsunami Earthquake Risk Assessment is a joint project between Schmidt Ocean Institute, the Earth Observatory of Singapore, the Indonesian Institute of Sciences, and the Institut de Physique du Globe de Paris.

Barbot's team is developing geophysical marine robots to probe the deformation of the seafloor. The end goal is to extend geodetic measurements offshore to better understand earthquakes, tectonic processes and tsunami hazards.

The largest earthquake ever recorded in an ocean happened in 2012 in the Indian Ocean; yet even with modern instruments, scientists have debated how this rupture occurred. This project will use new datasets to fully understand this earthquake.
