Earthquake near West Bishop, CA

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 14 km (9 mi) from the epicentre. In West Bishop, 9 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: West Bishop 9 km, intensity II · Dixon Lane-Meadow Creek 10 km, intensity II · Bishop 13 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 60 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.2 would have released about 32 times as much.

1. Mineral, Virginia 2011 M 5.8 250,000× the energy of this one
2. Magna, Utah 2020 M 5.7 180,000× the energy of this one
3. Around the size people start to feel M 3.0 16× the energy of this one
4. This earthquake M 2.2 about 60 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.
