This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.

At this magnitude and depth, people at rest would likely notice it out to about 29 km (18 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: Rincón in town, intensity II · Aguada 9 km, intensity II · Aguadilla 15 km, intensity II · Mayagüez 19 km, intensity II · Rafael Hernandez 24 km, intensity II · San Sebastián 28 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 800 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.0 would have released about 32 times as much.

  1. Northridge, California 1994 M 6.7 420,000× the energy of this one
  2. Mineral, Virginia 2011 M 5.8 19,000× the energy of this one
  3. Magna, Utah 2020 M 5.7 13,000× the energy of this one
  4. This earthquake M 3.0 about 800 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

No earthquake of M4 or more has been recorded within 50 km since our catalogue begins in 2016.

Before 2016, the USGS record lists 10 earthquakes of M5 or more within 50 km; the five largest:

  1. 7.1 24 km NNW of San Antonio, Puerto Rico · 41 km N of this epicentre
  2. 6.4 32 km NW of Aguadilla, Puerto Rico · 34 km NNW of this epicentre
  3. 6.3 6 km WNW of Aguadilla, Puerto Rico · 13 km NNE of this epicentre
  4. 6.1 15 km WNW of San Antonio, Puerto Rico · 24 km N of this epicentre
  5. 6.1 18 km NNW of San Antonio, Puerto Rico · 35 km NNE of this epicentre

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.
