STRONG AFTERSHOCKS (Magnitude 5 and larger) –
At this time (immediately after the mainshock) the probability of a strong and possibly damaging aftershock IN THE NEXT 7 DAYS is approximately 30 PERCENT.
EARTHQUAKES LARGER THAN THE MAINSHOCK –
Most likely, the recent mainshock will be the largest in the sequence. However, there is a small chance (APPROXIMATELY 5 TO 10 PERCENT) of an earthquake equal to or larger than this mainshock in the next 7 days.
WEAK AFTERSHOCKS (Magnitude 3 to 5) –
In addition, approximately 12 to 40 SMALL AFTERSHOCKS are expected in the same 7-DAY PERIOD and may be felt locally.
This probability report is based on the statistics of aftershocks typical for California. This is not an exact prediction, but only a rough guide to expected aftershock activity. This probability report may be revised as more information becomes available.
