Hospital and government entities should establish comprehensive emergency plans for tsunami-prone communities. The evacuation of affected individulas before the arrival of the first tsunami wave should be a priority when a tsunami alert is issued.
Well-developed plans rely on collaboration and simulation to ensure relocation of affected persons to safe areas (such as shelters) and/or planning for appropriate escape routes. The inclusion of tsunami hazard and damage scenarios should be included (when appropriate) to identify suitable shelters, determine escape routes and consider the possibility of debris accumulation which can affect accessiblity of established routes.
A large earthquake off the coast of Alaska could send a devastating tsunami towards California, causing the evacuation of nearly 1 million people and causing $10 billion in damage, a recent U.S. Geological Survey revealed.
USGS scientists met with state and local officials on Wednesday to discuss what might happen if a 9.1 earthquake — similar to the one that struck Japan in 2011 — occurred offshore of the Alaskan Peninsula. Researchers called the scenario “hypothetical, yet plausible,” warning officials to prepare for the worst.
A large tsunami hitting California would cause major flooding in Long Beach and parts of Orange County and force 750,000 people to evacuate coastal areas in just a few hours, according to an extensive simulation published Wednesday by the U.S. Geological Survey.
The study, released two years after a tsunami killed thousands in Japan, identified several communities that are particularly vulnerable to flooding because of their low elevation and lack of protection from waves.:
The NTHMP was formed in recognition of the tsunami threat to Oregon, Washington, and northern California from a magnitude 9 earthquake on the Cascadia subduction zone, the April 1992 earthquake and tsunami on the Cascadia subduction zone in northern California, and the loss of life and property in Japan due to the 1994 Hokkaido, Japan earthquake and tsunami.
The NTHMP is a partnership between NOAA, the United States Geological Survey (USGS), the Federal Emergency Management Agency (FEMA), the National Science Foundation (NSF), and the 28 U.S. Coastal States Territories, and Commonwealths. For more information:
The Pacific Tsunami Warning Center (PTWC) is responsible for providing warnings to international authorities, Hawaii, and U.S. territories within the Pacific basin. The two Tsunami Warning Centers coordinate the information being disseminated. For more information:

Hospitals, schools, playgrounds, factories and homes are often built in areas vulnerable to tsunamis. The TsunamiReady Program, developed by the National Weather Service, is designed to help cities, towns, counties, universities and other large sites in coastal areas reduce the potential for disastrous tsunami-related consequences.
Since June 20, 2001, TsunamiReady has helped community leaders and emergency managers strengthen their local operations. TsunamiReady communities are better prepared to save lives through better planning, education and awareness. Communities have fewer fatalities and property damage if they plan before a tsunami arrives. No community is tsunami proof, but TsunamiReady can help minimize loss to your community. Find out what’s involved in becoming TsunamiReady.
For tsunami hazards, CGS is working closely with CalEMA and the Tsunami Research Center at the University of Southern California to produce statewide tsunami inundation maps and preparedness information for California. 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.
Is your hospital at risk for earthquakes or tsunami? Earthquakes can occur everywhere in California. In addition to the shaking caused by earthquakes, landslides, surface fault ruptures and liquefaction can all occur. These effects can cause injury or property damage.
The Intergovernmental Oceanographic Commission (IOC) of UNESCO developed this guide as a basis for forming a strong community tsunami readiness policy. It provides a general plan of action and basic framework for dealing with the unique hazards resulting from tsunamis. This guide outlines the construction and maintenance of defensive structures and discusses how current disaster prevention and emergency response planning can be improved by using research on past tsunamis.
Each planner must take into account their community’s unique circumstances and review their current action plans. In doing so, planners will be able to adapt each community’s unique topography, special circumstances, changes in the social environment a nd scientific research to the proposed overall strategy contained in this guide.
After a damaging earthquake, having the strength to recover will rely on those close to us for personal strength in the face of an overwhelming situation. Many Californians will turn to the California Earthquake Authority (CEA) to get the financial strength they’ll need to rebuild.
SCEC’s science goal is to understand the physics of the Southern California fault system and develop a model of key aspects of earthquake behavior. To do this, SCEC organizes interdisciplinary research spanning all aspects of earthquake system science, disciplinary activities such as data collection and analysis, and special projects in information technology, earthquake predictability, and other applied research.
