M>2.8 Coastal Shove Off Monterey Coast
Posted by Don in Hollister on May 01, 2005 at 14:43:32:

Hi All. Looks like the coastal shove has moved a little further out in the Pacific Ocean. The M>2.8 (if it holds up) is located on the Paleo Subduction Zone. It is further south and a little more to the west then the two M>6.0 quakes in 1926.

“Two large earthquakes in October 1926 (estimated Richter magnitude 6.1) and their three aftershocks cracked plaster in Santa Cruz and also brought down a number of chimneys. Numerous plate glass windows were broken along Pacific Avenue. To the north, the city water main was broken at Laguna Creek, and at Davenport groceries were thrown from the shelves of the store (Santa Cruz Sentinel, 23 October 1926) [20,19]. An earthquake in February 1927, believed to be related to those in the fall of 1926, also cracked plaster, and articles fell from shelves in Santa Cruz. The epicenters, located from maximum recorded intensities for all these earthquakes, probably were in or just outside of southern Monterey Bay.”

Note: No aftershocks were recorded in the ANSS catalog for the two M>6.0 quakes. Take Care…Don in creepy town
