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 27 km (17 mi) from the epicentre. In Animas, 11 km away, the estimate is intensity II (weak). 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: Animas 11 km, intensity II · Arecibo 12 km, intensity II · Garrochales 12 km, intensity II · Barceloneta 14 km, intensity II · Tierras Nuevas Poniente 17 km, intensity II · Carrizales 18 km, intensity II · Manatí 19 km, intensity II · Hatillo 21 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 590 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.9 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 26,000× the energy of this one
- Magna, Utah 2020 M 5.7 18,000× the energy of this one
- Around the size people start to feel M 3.0 1.6× the energy of this one
- This earthquake M 2.9 about 590 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 4.4 on 2018-12-09 — about 200 times the energy of this one.
Before 2016, the USGS record lists 3 earthquakes of M5 or more within 50 km:
- 5.8 12 km N of Garrochales, Puerto Rico · 7 km ENE of this epicentre
- 5.8 4 km E of Moca, Puerto Rico · 49 km WSW of this epicentre
- 5.0 3 km N of Brenas, Puerto Rico · 31 km E 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.
