NOAA reports that a 5.3 richter rumbled just over a half mile under the ocean 145 miles due west of Coos Bay this evening at 8:13 pm. No reports of any major shaking. Many residents said they didn’t even know that an earthquake had occurred. NOAA reports there was no chance of a tsunami.
The quake occurred in the area of the Cascadia Subduction Zone area off the coast, the area of frequent small earthquakes as shown in the map with all the yellow circles. It is another reminder that those living along the coast need to be prepared for a major quake. Scientists recently upgraded their estimate of the chances of a major 8 or 9 richter earthquake centered 150 to 250 miles off off the Oregon Coast at 10 to 15% within the next fifty years. They say everyone on the coast needs to have emergency food, survival equipment and know the fastest route to higher ground if they live near the ocean. Scientists say that there is evidence that the Cascadia Subduction Zone is capable of creating a tsunami 80 to 100 feet high, so knowing the fastest routes to the highest places is one’s key to survival.
