Are earthquakes increasing in frequency and intensity?
They discovered that while the frequency of magnitude 8.0 and higher earthquakes has been slightly elevated since 2004 – at a rate of about 1.2 to 1.4 earthquakes per year – the increased rate was not statistically different from what one might expect to see from random chance.

14, the U.S. Geological Survey forecast estimated a 3% chance of one or more quakes larger than magnitude 6.4 in Puerto Rico over the next seven days. It also noted that the region should expect between 40 and 210 smaller quakes, with magnitude 3 or larger — sizes that are likely to be felt — during that time.
