A 3.9 magnitude earthquake hit Dublin, California, on the Calaveras fault, felt by many residents across the Bay Area. Occurring at 7:46 p.m., it highlighted geological interconnections with the nearby Hayward fault. Seismologist Angie Lux noted the earthquake's location may indicate stress accommodation between the two faults. Following the main quake, 18 aftershocks were recorded, which is considered normal. While no damage or injuries were reported, concerns linger about the potential for a larger earthquake along the Hayward fault, emphasizing the need for preparedness among residents.
"An interesting thing about this earthquake, we were talking about with our department today is, it's actually west of the Calaveras fault and kind of in between the Hayward and Calaveras fault, so this is maybe joining the two faults and accommodating some of the stress between these two faults," said UC Berkeley seismologist Angie Lux.
"There have been I think 19, 18 other earthquakes that have happened since that magnitude 3.9 earthquake and that's very normal and most people won't feel them. There is a small chance this could be a foreshock to a larger earthquake, but we will never know until that larger one happens, if it ever does," she said.
"I did personally feel the earthquake. It was a quick jolt with a slow roll afterwards. There were no reports of damage. There were no calls for service," said Battalion Chief Stephen Lund with the Livermore-Pleasanton Fire Department.
Seismologists still say the biggest concern for a 7.0 plus quake is still on the Hayward fault. Another reminder to be prepared.
