Project Status for the Gulf of Mexico (GOM)    

BACKGROUND

The Gulf of Mexico states have been included to the U.S. Tsunami Warning System since January 2005. The main purpose of the warning system is to enable local emergency management to act in response to warnings. To plan for the warning response, emergency managers must understand what specific areas within their jurisdictions are threatened by tsunamis. Potential tsunami sources for the GOM are local submarine landslides and earthquakes (induced co-seismic tsunami source) along the Caribbean plate boundary faults. However, preliminary modeling of potential tsunami sources outside the GOM has indicated a very low threat and may not pose a tsunami hazard to the GOM coastal communities or infrastructure. Nevertheless, recent assessments of tsunami hazards along the Gulf of Mexico (GOM) carried out by the U.S. Geological Survey (USGS) and the National Tsunami Hazard Mitigation Program (NTHMP) have identified underwater landslides as the primary potential source of tsunami generation. Although a massive underwater landslide in the GOM is considered a potential hazard, the probability of such an event is quite low. The probability of occurrence is related to large ancient landslides which were probably active prior to 7,000 years ago when large quantities of sediments were emptied into the GOM. However, nowadays sediments continue to empty into the GOM mainly from the Mississippi river. The sediment supply contributes to slope steepening and also to the increasing of the excess pore water pressure in the underlying soils, which may lead to further landslide activities. Recent evidence from seismic records of small-scale energetic seismic-waves in the GOM have confirmed that there is a probability of recurrence.
