California tremors raise fears of the ‘Big One’
LOS ANGELES: California may be hit by a strong earthquake, after geologists discovered a succession of tremors.
The California Emergency Services Office issued a warning after fears the rumblings may trigger a larger quake affecting southern California, including Los Angeles, San Diego and San Bernardino.
The tremors, three to seven miles beneath the Salton Sea north of San Diego, started about 4am on Sept 26 and lasted more than 24 hours. Three of them measured above a magnitude of four.
Data showed about a 1% chance of a quake of magnitude seven or greater hitting within the next week. Such a disaster could kill 1,800 people and cost US$200 billion (RM824.9 billion) in damage, according to a simulation. However, the likelihood of such a quake decreases with each day.
It is the third time such tremors have happened in the area since sensors were installed in 1932.
The last time Salton Sea quakes brought devastation was in 1987 when a 5.9-magnitude quake hit San Gabriel Valley. – The Independent
