Historical records indicate that the Oregon coast has been hit with a number of tsunamis. These can be caused by nearby or distant earthquakes. Destruction of property may be great, but loss of life need not be if people are prepared and act quickly. When caused by a distant earthquake a warning will come from news media, weather alert radios, or coastal warning sirens. When caused by a nearby earthquake the warning will be felt. When the ground stops moving it is important to get to high ground quickly, and then stay there for 12 hours. A tsunami caused by a nearby earthquake could strike in as little as 15 minutes and waves could continue to arrive for 12 hours.
