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 74 km (46 mi) from the epicentre. In Escondido, 41 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: Julian 18 km, intensity III · Borrego Springs 27 km, intensity III · San Diego Country Estates 28 km, intensity III · Ramona 29 km, intensity III · Aguanga 30 km, intensity III · Anza 36 km, intensity II · Escondido 41 km, intensity II · Alpine 45 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 5 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.7 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 1,500× the energy of this one
  3. Magna, Utah 2020 M 5.7 1,100× the energy of this one
  4. This earthquake M 3.7 about 5 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 10× more

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 5.2 on 2016-06-10 — about 180 times the energy of this one.

Before 2016, the USGS record lists 8 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.0 16km WSW of Oasis, CA · 43 km ENE of this epicentre
  2. 5.5 1km ENE of Borrego Springs, CA · 28 km E of this epicentre
  3. 5.4 20km NNW of Borrego Springs, CA · 27 km NE of this epicentre
  4. 5.3 18km ESE of Anza, CA · 31 km NNE of this epicentre
  5. 5.2 10km ESE of Anza, CA · 34 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.
