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
Earthquake strikes Iran A magnitude 4.3 earthquake hit the Gerash region in Iran on Tuesday, according to the US Geological Survey. The seismic event occurred at a depth of 10 kilometers, as reported by the USGS. The tremor, which was recorded in the early hours of the day, caused minor shaking in the area but did not result in any immediate reports of damage or casualties. Local authorities have not issued warnings of further activity, and the USGS has not indicated any potential for larger quakes in the region. The event is considered relatively minor compared to historical seismic activity in Iran, which has experienced more significant earthquakes in the past. While the Gerash region is not known for frequent seismic events, the country as a whole lies in a seismically active zone due to its location along the Eurasian and Arabian tectonic plates. This tectonic activity has led to several notable earthquakes in recent years, including a 7.3 magnitude quake in 2023 that caused widespread damage in the city of Tabas. The current tremor is likely a result of the same underlying geological processes that contribute to Iran's seismic risks. The USGS typically provides real-time data on earthquakes, including their magnitude, depth, and location, to help scientists and authorities assess potential impacts. In this case, the agency's data suggests the quake posed no immediate threat to populated areas. However, residents in the region are advised to remain vigilant and follow any updates from local emergency services. The incident highlights the ongoing seismic activity in the region and underscores the importance of preparedness for such events. While the current earthquake was not significant, it serves as a reminder of the potential for larger, more destructive quakes in the future.#iran #usgs #us_geological_survey #gerash_region #tectonic_plates
