A 4.5 magnitude earthquake shook the North Bay Area on Saturday morning, raising concerns among local residents. Despite the lack of reported damage, the event garnered significant attention. Meteorologist Darren Peck offered insights into the earthquake's location, its impact on the Bay Area, and the weather forecast for Sunday.

The quake struck at 5:00 a.m. in Sonoma County's geothermal field, known as the Geysers. Although it wasn't powerful enough to cause damage, the tremors were felt over a vast area, reaching as far as the city and down to the Tri-Valley. This seismic event was unusual as it didn't occur on any of the well-known Bay Area faults but in the geothermal field, where heat stored in the ground can cause underground molten rock to expand and fracture rocks.

Peck explained that most earthquakes in the region have a magnitude below 3. However, larger quakes have occurred in the past, such as a 5.0 magnitude earthquake in 2016. While these events are infrequent, they serve as a reminder of the region's geological activity.

Peck also provided a brief weather update for the area. San Jose experienced temperatures in the mid-70s, while Walnut Creek saw temperatures in the mid-80s. Pleasanton reached 86 degrees, with some areas hitting 90 degrees during the 5:00 p.m. newscast. Sunday's weather is expected to be slightly warmer, with a one or two-degree increase in temperatures.

The 4.5 magnitude earthquake serves as a reminder of the seismic activity in the Bay Area and underscores the importance of preparedness for such events. Although no damage was reported this time, residents should stay vigilant and aware of their surroundings.
