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?”
Starting points:
- Could It Happen Here?
- Life of a Tsunami
- Local Tsunamis in the Pacific Northwest
-
- Not all tsunamis are generated by earthquakes
- Tsunamis can be caused by volcanoes, landslides, and even atmospheric disturbances
- Data from tide gauges can help unravel the complex physics of these sources
Tsunami events:
March 11, 2011, Japan
- Preliminary simulations of the tsunami
- Notes from the field: International Tsunami Team visits Japan before (2010) and after (May 2011);
plus eyewitness accounts from California on March 11
