California earthquake rattles LA; centered near the deadly 1987 temblor
The U.S. Geological Survey downgraded the quake from a preliminary 4.6. The earthquake, centered just southwest of El Monte in eastern Los Angeles County, was felt as far south as San Diego, according to early reports.
There were no "significant" reports of damage and no injuries reported, the Los Angeles Police Department and L.A. Fire Chief Ralph Terrazas tweeted following an immediate assessment early Saturday.
Seismologist Lucy Jones said the location was close to where a magnitude-5.9 quake struck in 1987, killing several people and causing more than $200 million in damage, the Times reported.
The 1987 quake was determined to have been caused by the Puente Hills thrust fault that goes from the San Gabriel Valley to downtown Los Angeles, meaning a large quake could be even more hazardous than an even bigger one along the infamous San Andreas Fault, which skirts the city, according to the Times.
Jones said there was a 5 percent chance that Friday's 4.6 quake could be a foreshock to a larger quake, KABC-TV of Los Angeles reported. She added on later on Twitter that the chance would go down to less than 1% by Saturday evening.
