The U.S. Geological Survey says an earthquake that shook much of the central Bay Area at 9:26 p.m. Sunday night was a 3.0-magnitude shake centered near the Hayward Fault in the Berkeley Hills. Here at KQED Sunday Night Seismic Reporting Central — my house in North Berkeley — the quake was very short and mild. It lasted less than 10 seconds and caused some light rattling of our old wood-frame house.

That impression of the temblor seems to be confirmed by a quick look at the USGS “Did You Feel It?” response page. The more than 2,000 quake reports from members of the public show the temblor was felt from Half Moon Bay and Mountain View to the south up to Petaluma and Napa in the north and from Daly City east to Livermore. Virtually all the responses characterize the shaking as “weak” or “moderate.”

The USGS also recorded a 1.8 tremor at about the same location as the first shake at 9:29 p.m.

(And the news within the news: While many Geological Survey research programs have been suspended because of the ongoing government shutdown, and while agencies like NASA have all but shuttered their websites, the USGS continues to keep its earthquake reporting operational. However, those pages include this official caveat: “Due to a lapse in Federal funding, the USGS Earthquake Hazards Program has suspended most of its operations. While the USGS will continue to monitor and report on earthquake activity, the accuracy or timeliness of some earthquake information products, as well as the availability or functionality of some web pages, could be affected by our reduced level of operation.”)
