TsuInfo Alert is a bi-monthly newsletter that links scientists, emergency responders, and community planners to the latest tsunami research.
The California Tsunami Program (CTP) is a collaboration between the the California Geological Survey (CGS) Tsunami Unit, the California Governor’s Office of Emergency Services (Cal OES), and entities at the local level (counties, cities, community workgroups). For tsunami hazard mapping, the CTP works closely with the Tsunami Research Center at the University of Southern California and others to produce statewide Tsunami Hazard Area Maps and preparedness information for California. The CGS is also the scientific representative for California on the National Tsunami Hazard Mitigation Program Coordinating Committee, a state and federal cooperative responsible for developing policies and standards for tsunami mitigation efforts in the United States and its territories.
