Monday Morning Quake Hits East Bay A 2.8-magnitude earthquake struck San Ramon early Monday morning, according to the U.S. Geological Survey. The tremor occurred at 3:34 a.m., just north of Bollinger Canyon Road and east of Alcosta Boulevard, near the Bridges Golf Club. The quake had a depth of 8.9 kilometers, with nearby residents reporting weak to light shaking. This event marks the latest in a series of seismic activities affecting the area since November. San Ramon has experienced multiple quakes, including another 2.8-magnitude tremor on Friday, March 13. The city’s location along the Calaveras Fault contributes to frequent seismic activity, as micro-faults within the main fault line can trigger swarms of small quakes. Fluid movement through cracks in these faults often leads to rapid sequences of minor tremors. The city has also hosted discussions on earthquake preparedness. On February 27, San Ramon organized a Q&A session featuring local mayors, Supervisor Candace Andersen, SRVFPD Chief Jonas Aguiar, and UC Berkeley seismologist Dr. Angie Lux. The event addressed concerns about the region’s seismic activity and strategies for community readiness. While the recent quake did not cause significant damage, it underscores the ongoing challenges posed by the area’s geological conditions. Residents and officials continue to monitor seismic trends, with efforts focused on enhancing resilience and public awareness.#san_ramon #calaveras_fault #bridges_golf_club #candace_andersen #jonas_aguiar
A 2.8 magnitude earthquake shook near San Ramon, California, on March 23, according to the U.S. Geological Survey. The tremor occurred at 3:34 a.m. and was centered approximately 2 miles east-southeast of San Ramon, at a depth of 6 miles. Residents who felt the quake are encouraged to submit reports through the USGS Felt Report form. Earthquakes are measured by their magnitude, which reflects the energy released at the earthquake’s source. The USGS explains that this system replaces the older Richter scale. Quakes ranging from 2.5 to 5.4 magnitude are typically felt but rarely cause significant damage. Earthquakes below 2.5 magnitude are generally not noticeable to most people. While earthquakes can occur anywhere, they are most common in regions such as Alaska, California, Hawaii, Oregon, Puerto Rico, and Washington. The Department of Homeland Security notes that these events can trigger secondary hazards like fires, tsunamis, landslides, or avalanches. Globally, it is estimated that 500,000 earthquakes are detectable each year, with 100,000 of those felt by humans and 100 causing damage. During an earthquake, experts recommend immediate protective actions. If in a vehicle, drivers should pull over, stop, and set the parking brake. Those in bed should turn face-down and cover their heads with a pillow. Outdoor individuals should avoid buildings and not enter structures. Inside, people should stay put, avoid doorways, and follow the "drop, cover, and hold on" protocol. For those using wheelchairs or walkers, wheels should be locked, and users should remain seated until shaking stops. Covering the head and neck with arms is advised, and if possible, crawling under a sturdy table. If no shelter is available, moving to an interior wall away from windows is recommended.#california #department_of_homeland_security #us_geological_survey #san_ramon #earthquake_bot
A 2.8 magnitude earthquake struck near San Ramon, California, on March 23, according to the U.S. Geological Survey. The tremor occurred at 3:34 a.m. and was centered approximately 2 miles east-southeast of San Ramon, at a depth of 6 miles. Residents in the area were advised to report their experiences through the USGS Felt Report form to help refine earthquake data. Earthquakes are measured by their magnitude, which reflects the energy released at the fault line. The USGS explains that this system replaces the older Richter scale. Quakes between 2.5 and 5.4 magnitude are typically felt by people but rarely cause significant damage. Earthquakes below 2.5 on the scale are generally too small to be noticed by most individuals. While earthquakes can occur anywhere, they are most common in regions such as Alaska, California, Hawaii, Oregon, Puerto Rico, and Washington. These areas are prone to seismic activity due to their proximity to tectonic plate boundaries. Globally, it is estimated that 500,000 earthquakes are detectable each year, with 100,000 of those felt by people and only 100 causing structural damage. During an earthquake, immediate safety measures are critical. If in a vehicle, drivers should pull over to a safe location, stop, and engage the parking brake. Those in bed should lie face-down and protect their head with a pillow. Outdoor individuals should avoid buildings and stay clear of structures, while those inside should remain indoors, avoiding doorways. The recommended protocol is to "drop, cover, and hold on," which involves getting to the ground, taking cover under a sturdy object, and holding on until the shaking stops. For wheelchair or walker users, ensuring wheels are locked and staying seated is advised.#california #earthquake #us_geological_survey #san_ramon #felt_report
