It was seismically quiet week in and around Orange County, with the region mostly recording microquakes that weren’t felt by many people. One tiny shake occurred on an unidentified fault not far from Disneyland. Another happened east of Rancho Santa Margarita. And there was a hiccup on the Newport-Inglewood fault, in the Newport area. The notable action occurred to the south, along the U.S.-Mexico border, where a series of small quakes led to a 4.0 shaker. Both sides of the border have been twitching for about a week.
