Seismologist Recalls 2007 Quake Nearby
Cal Tech seismologist Lucy Jones referenced a 2007 earthquake while talking with the KNTV-TV about the 5.1 quake that hit near San Jose on Tuesday.
Jones told the station a 5.4-magnitude earthquake near Alum Rock was "pretty close" to where the U.S. Geological Survey (USGS) said the epicenter of Tuesday's earthquake was located. Both earthquakes were reported as being near the Calaveras Fault.
Jones said people near Alum Rock and San Jose were likely to have felt Tuesday's earthquake "pretty strongly" and that it may have caused some items to fall off shelves in homes nearby for some people, but that it likely did not result in serious structural damage.
"A California building shouldn't be having trouble from this," Jones said.
Jones also referenced an earthquake that occurred near Ridgecrest in 2019, which did cause damage to structures in the area. That earthquake was measured at a 6.4 magnitude and had a 7.1-magnitude aftershock two days later. Jones told the station Tuesday's earthquake was the first she had felt since the Ridgecrest earthquakes.
In a Tuesday afternoon tweet, Jones identified Tuesday's earthquake as the largest in the area since 2014. The USGS identifies that earthquake, which occurred along the West Napa Fault in August 2014, as "the largest earthquake in over 25 years to hit the San Francisco Bay Area" and said it caused "significant damage" in Napa Valley.
