This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.

At this magnitude and depth, people at rest would likely notice it out to about 17 km (11 mi) from the epicentre. Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.

Likely felt in: Tallaboa Alta 7 km, intensity II · Magas Arriba 7 km, intensity II · Guayanilla 8 km, intensity II · Adjuntas 10 km, intensity II · Tallaboa 10 km, intensity II · Yauco 11 km, intensity II · Ponce 16 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 41 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.1 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 370,000× the energy of this one
Magna, Utah 2020 M 5.7 260,000× the energy of this one
Around the size people start to feel M 3.0 23× the energy of this one
This earthquake M 2.1 about 41 lb of TNT

Energy from the Gutenberg–Richter relation (log₁₀E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.

For this area

The largest earthquake within 50 km since 2016 was M 6.4 on 2020-01-07 — about 2,900,000 times the energy of this one.

Before 2016, the USGS record lists one earthquake of M5 or more within 50 km:

5.8 4 km E of Moca, Puerto Rico · 49 km NW of this epicentre May 16, 2010

Since 2016: the QuakeIndex catalogue (US, M1.5+), built from the USGS FDSN event service. Before 2016: USGS ComCat, M5+ from 1900. Distances are between epicentres. This is the record, not a forecast.
