Small Earthquake Rattles San Francisco Bay Area

For those you who forgot, California is the shake and bake state. And the fault line decided to remind us of that yesterday. A small earthquake gave the San Francisco Bay Area a quick shake on Monday night, reminding residents that they live in earthquake country. The tremor, which had a magnitude of 3.9, struck just after 7:45 p.m. and was centered near Dublin, according to the U.S. Geological Survey (USGS). Initially, the quake was reported as a 4.0, but after further review, scientists slightly downgraded the magnitude.
The earthquake originated about 7 miles (11.7 kilometers) beneath the surface, which is fairly typical for the region. People from various parts of the Bay Area reported feeling the jolt, with reports coming in from as far north as the border of Solano and Yolo counties and as far south as Santa Cruz. While some residents may have been startled by the sudden movement, there were no immediate reports of injuries or damage.
According to the USGS, the quake was classified as a Level IV on the Modified Mercalli Intensity Scale, meaning it caused light shaking but no significant impact. For context, the scale ranges from I (barely felt) to X (extreme shaking with major destruction). A Level IV quake is enough to rattle windows, shake furniture, and give people a brief moment of surprise, but it’s not strong enough to cause any real damage.
For long-time Bay Area residents, these minor quakes are just part of life. Many took to social media to share their experiences, with some joking that it was just another reminder to check their emergency kits. While this was a small quake in the grand scheme of things, it’s always a good idea to stay prepared, after all, the Bay Area sits on several major fault lines, and bigger quakes are always a possibility.
I was laughing with my roommate when my house started twerking, but I can see how such a jolt can be unsettling to Northern California newcomers.
