San Fransisco earthquake
Two relatively low-magnitude earthquakes struck the San Francisco area on Thursday night.
The earthquakes occurred almost 22 years to the day of the San Francisco earthquakes that halted the 1989 World Series. Earlier on Thursday, another earthquake struck near the San Antonio area in Texas.
A 4.8 magnitude earthquake struck Karnes County - about 47 miles away from San Antonio - at approximately 7:24 a.m. local time.
The previous largest earthquake was a 4.3 magnitude 'quake in 1993.
