A magnitude 5.4 quake at 4:07 a.m. Friday was so far the strongest aftershock.

Seismologists say there have been 1,700 aftershocks in the wake of the strongest earthquake to hit Southern California in 20 years but the chances of another large temblor are diminishing.

A magnitude 5.4 quake at 4:07 a.m. Friday is so far the strongest aftershock of Thursday's 6.4 quake, which struck in the Mojave Desert near the town of Ridgecrest.

Zachary Ross of the California Institute of Technology says the number of aftershocks might be slightly higher than average. He also says a quake of that size could continue producing aftershocks for years.

The quake caused some damage to buildings and roads in and around Ridgecrest.

However, seismologists say it's unlikely the quake will affect any fault lines away from the immediate area, such as the mighty San Andreas.
