Tsunami and Earthquake Research
Field Studies
Our researchers collect data from sites of recent tsunamis to gain a better understanding of the potential impact on other regions with high probability of tsunamis. Their work helps inform coastal planning, protection, and resiliency.

Learn about the earthquakes that triggered recent tsunami events, and watch computer simulations of each tsunami from different angles.

Here you will find general information on the science behind tsunami generation, computer animations of tsunamis, and summaries of past field studies.
The scope of tsunami research within the USGS, however, is broader than the topics covered here. USGS researchers have also provided critical research toward understanding how sediments are transported during tsunami runup and deciphering the geologic record of prehistoric tsunamis. The USGS collaborates closely with the NOAA Center for Tsunami Research.
As part of the National Tsunami Hazard Mitigation Program, the USGS has also upgraded the seismograph network and communication functions of the U.S. Tsunami Warning Center.
Soon after the devastating tsunami in the Indian Ocean on December 26, 2004 many people have asked, “Could such a tsunami happen in the United States?” As a starting point, read “Could It Happen Here?”
