A series of small earthquakes shook San Leandro beginning just before midnight with a magnitude 3.0 earthquake. That was followed, less than five minutes later, by a magnitude 2.6 earthquake, and a 1.7 magnitude earthquake at just after one in the morning.
According to the US Geological Survey, the epicenter of the earthquakes was along the Hayward Fault, in unincorporated San Leandro in the area of Fairmont Ridge, between the Alameda County Juvenile Justice Center and Lake Chabot.
Earthquakes with a magnitude smaller than 4 are not expected to cause any damage and news reports about the quakes have not indicated that there was any damage.
On October 21, 1868, a magnitude 7 earthquake at the southern end of the Hayward Fault destroyed the Alameda County Courthouse, which was located in San Leandro near the present site of St. Leander Church. In Hayward, "almost every building was damaged extensively or wrecked."Posted by Mike Katz-Lacabe at May 30, 2010 7:38 AM | TrackBack
