Exercise LANTEX12: Participant Handbook: An Atlantic/Gulf of Mexico Tsunami Warning Exercise: March 28, 2012 [open pdf - 5MB]
From the Summary: "The US NOAA [National Oceanic and Atmospheric Administration]/National Weather Service and the National Tsunami Hazard Mitigation Program will be conducting a tsunami exercise on March 28, 2012 to assist tsunami preparedness efforts along the U.S. and Canadian east coasts, the Gulf of Mexico, and in Puerto Rico and the Virgin Islands. The LANTEX12 [Large AtlaNtic Tsunami Exercise 12] tsunami exercise consists of two separate scenarios. Scenario 1 simulates a Gulf of Mexico earthquake west of Florida which generates a tsunami by triggering a submarine slump on the continental slope. The second scenario consists of an earthquake located east of South Carolina which also generates a tsunami by triggering a slump along the continental slope further to the east."
