A magnitude 0.2 earthquake was recorded 10 km (6 mi) SSW of Idyllwild, CA, at 7:37 am PDT on 2 October 2026 (14:37 UTC). This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.

Earthquakes near other towns within 30 km: Idyllwild-Pine Cove, Valle Vista, Anza, East Hemet, Hemet, San Jacinto.

How big was it?

This earthquake released about 0.062 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 1.2 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 240,000,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 170,000,000× the energy of this one
  3. Around the size people start to feel M 3.0 15,000× the energy of this one
  4. This earthquake M 0.2 about 0.062 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 5.2 on 2016-06-10 — about 30,000,000 times the energy of this one.

Before 2016, the USGS record lists 12 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.7 The 1918 San Jacinto, California Earthquake · 21 km WNW of this epicentre
  2. 6.0 The 1986 North Palm Springs, California Earthquake · 40 km NNE of this epicentre
  3. 5.4 20km NNW of Borrego Springs, CA · 39 km SE of this epicentre
  4. 5.3 4km NNE of Desert Hot Springs, CA · 45 km NE of this epicentre
  5. 5.3 6km SSE of Hemet, CA · 16 km WNW 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.
