The earthquake just off the coast of Malibu and Santa Monica yesterday afternoon was unrelated to the larger one that occurred less than hour before. At 4:10 p.m., a minor 3.0 quake (LA Times said it was upgraded to 4.1) shook in the Santa Monica Bay. As usual, rarely-felt microquakes have been hitting the Los Angeles area daily, such as a small one this morning in Castaic and another one on Saturday in Northridge. more ›

It's been nearly a week of shaky ground out in the San Bernardino County city of Redlands. Since Wednesday, when we counted around 75 small quakes since the previous Saturday, there's been around 40 more quakes of varying, but inconsequential sizes, including a few over 3.0, which the USGS takes slightly more seriously on their listings by marking them in a bolded red. A 11:53 a.m. there was a light 3.4 earthquake, followed by a 3.3 a minute later. Then at 11:57, another 3.3, among a handful of other microquakes. Update: Apparently, there was a 3.6 quake at 11:56 a.m. that went unreported on USGS' site until 12:45 p.m. more ›

It's been a shaky day. The Death Valley area had a nice 3.6 earthquake earlier this morning, but the U.S.-Mexico border takes the cake. A 5.8 earthquake struck at 10:48 a.m. on the Mexico side some 20 miles from Mexicali in Baja Mexico and Calexico in California. It's been followed by various aftershocks: a 4.9 at 10:53 a.m., a 4.0 at 11 a.m., a 3.4 at 11:04 a.m., a 3.0 at 11:12 a.m. and a 2.7 microquake at 11:17 a.m. We've seen no reports of damage or casualties yet, but "buildings briefly swayed in San Diego"--about 100 miles away--reported The Desert Sun. more ›

A 1.5 magnitude earthquake shook in the Santa Susana Mountains, north of Granada Hills, Porter Ranch and Chatsworth, this morning. The 9:41 a.m. shaker is considered a microquake and is usually only felt by those extremely close to the epicenter. Another quake, measuring the same size, was reported in Claremont last night at 7:08 p.m. more ›

A 1.6 microquake struck near Newhall in the Santa Clarita Valley this morning. The 7:33 a.m. shaker was located in the San Gabriel Mountains, equidistant from Newhall in the Santa Clarita Valley and the city of San Fernando. Four minutes later, a 1.8 magnitude microquake struck near Devore in San Bernadino County. Then at 7:59 a.m., another 1.8 hit the Claremont Colleges/Rancho Cucamonga area. more ›

More little quakes to get you thinking about being prepared. A minor 3.1 magnitude earthquake struck near Trona, some 30 miles from Ridgecrest, in San Bernardino County at 4:59 p.m. Thus far, there have been no reports of damge or injuries and one reported aftershock, a 1.4 shaker, less than 10 minutes later. Earlier at 2:14 p.m., a 2.6 magnitude microquake struck off the coast of Orange County, near Laguna Beach and Dana Point. There was also a 2.2 quake near Anaheim last night and a 1.4 in Los Angeles this morning. more ›

A 1.4 magnitude earthquake struck 9 miles south of downtown Los Angeles in the Willowbrook area at 7:44 a.m. this morning. That low magnitude of a quake is probably equivalent to feeling like someone shut the door with force in the house next door. Nothing to worry about hear, just a constant reminder about being prepared. Yesterday, a 2.4 struck the Hawthorne-Lennox area. more ›

The land of Bruce and Bon Jovi is Full of...wimps. Southern California is no stranger to daily microquakes. In fact, just in the past week, we've had 15 of them. But when a quake shakes the bridge and tunnel crowd--like the 3.0 quake did last night--they freak. Via Gothamist, the Star-Ledger reports, "It sounded like an explosion, houses shook and dogs started barking." Other residents said it felt like a "bomb" and one man told WCBS 2, "I was upstairs on my computer, and all of a sudden I hear a boom, boom, boom, then a bang, bang, bang. My monitor almost fell off of my computer desk. So I immediately went downstairs to check on my grandma and ask her if she was alright or if she fell." more ›

It's the usual daily shakings here and there. If you were in Santa Monica yesterday and thought you felt something, you might have. There were three mini shakes. Tip of the day: There has been talk about using Twitter during emergencies. While cell phone use takes up bandwidth, texting does not, therefore helping save the cellular network from crashing. more ›

At 7:14 a.m., a 4.0 magnitude earthquake shook near Loma Linda, CA, about 58 miles east of Downtown Los Angeles. "Viewers called in to say they felt the shaker, but there were no reports of damage or injuries," according to KNBC. Shortly before at 6:49 and 7:05 a.m., two 2.6 microquakes rattled the same area. On Friday, the Great Southern California ShakeOut, which will include the largest earthquake drill ever in November, launched a blog. It's not a matter if there will be a massive earthquake, but when it will strike. more ›

Just a few minutes ago, we had a little earthquake here in The Valley. There were about three of them yesterday as well. While these microquakes could be a good sign of tension release, which could help avoid a major one, we still think you need to think about preparing yourself with a bare minimum of water.
