Yet another earthquake hit near San Leandro at 9:58 am. BART will run a bit slower for the next hour or so. This most recent quake follows last night's 3.6 quake that stuck in San Leandro, which followed scores of Californians thumbing their noses at the East Coast for overacting to a hefty 5.8 quake in Virginia. more ›

Did you feel it? A small tremor shook San Francisco this afternoon at 2:57 p.m., right on the 105-year anniversary of the Great Quake of 1906. According to USGMC, the earthquake registered 3.8, located just south of San Francisco and 2 miles south of Pacifica. We'll update as soon as we know more about today's minor anniversary nudge. more ›

We've reported on it before, but in the wake of the Japan earthquake, and a two-day meeting of seismologist at UC Berkeley, there's a renewed push to get an earthquake early-warning system set up in California. Japan had such a system, and it was able to give people in Tokyo 25-30 seconds to take cover before the March 11 earthquake struck. Nearer the epicenter, in Sendai, they only had about five seconds warning, because this early warning system is, actually, a little limited. (Unlike this guy's prediction methods, which give us days or weeks warning but are generally wrong.) more ›

A harrowing 8.9 earthquake hit Japan tonight. The New York Times reports: "A tsunami hit the coast of northeast Japan on Friday in the aftermath of an 8.9 magnitude earthquake about 80 miles offshore. Television images showed waves of more than 12 feet roaring inland. CNN reported that air and land transportation was severely disrupted." more ›

We felt it. Did you? A small earthquake was felt around San Francisco at around 4:10 this afternoon. A small ride, really. Nothing too big felt from SFist HQ. more ›

A 6.0 magnitude earthquake struck at 12:20 p.m., 35 miles west of Eureka, in the waters off the Humboldt coast right in the vicinity of the quake that hit on January 9th. There are no immediate reports of damage or injury, however the 6.5 quake last month did cause a fair amount of shaking and bounced a few houses off their foundations. We'll try to update you as we learn more. more ›

Scientists at U.C. Berkeley say they are close to completing work on the first earthquake early warning system in the U.S., which could give us anywhere from a few seconds to a full minute of warning when a big one is coming. They say even a few seconds worth of heads up could save lives, and therefore $10 million in stimulus funds are getting funneled to the project. more ›

Last week, our old pal Zennie reported that progressive activist couple Walter Riley and Barbara Rhine, both of Oakland, were missing after being in Haiti at the time of last week's earthquake. Walter's family -- which includes hip-hop artist Boots Riley and ABC News reporter Denise James -- had not heard from Walter or Barbara as of Wednesday. NBC Bay Area brings word over the weekend that the couple is safe and back in Oakland. "We are fine. We're physically fine, Barbara has a smashed finger," Riley said. "We're just angry with the slowness of the rescue efforts, the fact that people are dying unnecessarily." Mr. Riley is the chair of the Haiti Emergency Fund in Berkeley, and this was his first trip to Haiti since establishing the org. in 2004. more ›

The governor announced yesterday that since the quake had "disrupted utilities and caused damage to at least 175 structures," a state of emergency was necessary. the governor went on to point out that that damage in the area is expected to exceed $28 million. more ›

As most of you have probably heard, there was a devastating 7.0+ earthquake in Haiti yesterday. By some accounts, like The Haitian Blogger, the worst hit areas are in the mountainous region where both rich and poor (but mostly poor) built their homes. Lack of preparation for such an event — Haiti hasn't seen an earthquake like this in 200 years — has resulted in huge losses of life, numbering in the thousands, and a great many collapsed buildings, including the presidential palace. Five workers in Haiti's U.N. mission as well as the archbishop of Port-au-Prince are all believed dead. As brethren on shaky ground we're all probably feeling especially sad and mildly freaked out at the moment. more ›

A little before 4:30 p.m. on Saturday, according to USGS, an earthquake of a 6.4/6.5 magnitude "struck 15 miles SW of Eureka at 4:28 p.m." This, folks, is an above average one, coming on the heels of two small quakes that slightly rattled the Bay Area on Thursday and Friday. more ›

So, yeah... aftershocks. There have apparently been 10 in total, including the 3.8 one this morning at 11:50 a.m. This was the largest aftershock so far, occurring "shallowly" at about 6 miles deep, near Milpitas. Is the Calaveras fault trying to tell us something? more ›

Did you feel that? more ›

There was a small 3.2 quake that occurred in the East Bay at 3:30 p.m. today, one kilometer Northeast of El Cerrito. We at SFist felt it in the Tendernob area (the first one we've felt in our eight years in SF), as did many Twitter users. It was quick and felt like a large truck driving by. There have been no immediate reports of injury or damage. Apparently, there was also a 5.2 earthquake in Southern Alaska early this morning and a small quake in Wales last night. Occurrences like these are always good reminders to prepare for the Big One. more ›

Reports are coming in that there was a mild earthquake felt in San Francisco. We felt it too, but it could have been our the washing machine in the spin cycle. "I believe I just felt a 3-4 point earthquake just now," reports one SFist comments. more ›
