Afternoon Update for Puerto Rico - January 8, 2020

Sources/Usage: Public Domain.

Today's forecast [as of 03:24:26 EST] estimates that over the next 1 Week there is a 4 percent chance of one or more aftershocks that are larger than magnitude 6.4. It is highly likely that there will be many smaller earthquakes (M>3) over the next 1 Week. Magnitude 3 and above events are large enough to be felt near the epicenter. The rate of aftershocks will decline over time, but a large aftershock can increase the numbers again, temporarily.

Our forecasts change as time passes due to decline in the frequency of aftershocks, larger aftershocks that may trigger further earthquakes, and changes in forecast modeling based on the data collected for this earthquake sequence.
