A magnitude 3.8 earthquake struck near the Alum Rock area of San Jose Monday morning, according to the United States Geological Survey.
The temblor, which hit at 9:39 a.m., was centered 5 miles north-northeast of Alum Rock, 6 miles east of Milpitas and 9 miles northeast of downtown San Jose, according to the USGS. It was originally classified as a 3.9 magnitude quake before being downgraded.
People in cities such as San Jose, Fremont, Mountain View, Santa Clara, Los Gatos and Cupertino reported feeling the earthquake. Someone from as far away as Menlo Park also reported feeling shaking.
Reaction on social media was swift. "I'm in Campbell," Nancy Holme wrote on Twitter. "It felt like a car hit [our] house. One big jolt and it was over."
Patty Mitchell in San Jose's Willow Glen neighborhood took to Twitter to describe the quake as a "very quick but strong jolt."
"The TV here almost fell down," another person tweeted.
"Notable quake in San Jose. Follows hailstorm. If toads start coming coming down, I'm out of here ...," tweeted Sacramento Bee reporter Matt Burrows.
