look for information about the harmful effect of an earthquake, tsunami, and volcanic eruptions
Answers
Answer: A tsunami is a series of large ocean waves generated by either large, subduction zone earthquakes which deform the ocean floor or by landslides within or falling into the ocean. When the waves enter shallow depths near a coastline, they may rise to several feet or, in rare cases, tens of feet. If you are on a beach or in low coastal areas it is imperative you are aware that a tsunami could arrive within minutes after a severe earthquake. A tsunami’s danger period can continue for many hours after a major earthquake. Tsunamis can occur during any season of the year and at any time, day or night.
The California Governor’s Office of Emergency Services, Earthquake, Tsunami and Volcano Program is continuously researching, learning, and collaborating with science, industry, and academic experts to develop and confirm the latest, best available knowledge base to help make California’s residents and visitors safer in the event of tsunamic activity. By mapping potential inundation and evacuation areas, providing assistance in response and evacuation planning, implementing outreach, education and warning signage at the coast, as well as determining ways to improve preparedness and resilience of California’s ports and harbors, our staff strives to ensure everyone on the coast remains safe before, during and after the next tsunami.
