While searching through the California Department of Conversation's website, I came across the link for tsunamis. In brief, a tsunami is a series of waves which results from the occurrence of an earthquake, landslide, volcanic eruption, or a large meteor hitting the ocean. In terms of an earthquake, when they occur they cause a large movement of the sea floor which goes upward and results in the rise of water. Tsunamis can travel around 500 mph across the open ocean but slow down to about 30 mph as it approaches land. For an area prone to tsunamis, there are warning signs to help prepare for it. One of the most noticeable signs is the rapid receding of ocean water before the first wave of the tsunami hits. It's also important to note that not all earthquakes have resulted in a tsunami but in prone areas it is wise to be on the lookout so you can safely evacuate. In addition, there has been a tsunami preparedness brochure for boaters. This is because tsunamis in the state had caused about $100 million in damage to the maritime community. Furthermore, the California Geological Survey (CGS) provides us with geologic and seismic expertise to the public and works with the government to make statewide tsunami inundation maps and preparedness for the state. This website provides the state of California's residents with more than enough information regarding the history of the complex geology there as well as essential information on how to prepare for natural disasters.
