Alerts are on for .
Not a warning. An alert comes after USGS publishes a quake, usually minutes after the shaking. For early warning use ShakeAlert, through your phone's Wireless Emergency Alerts or the MyShake app.
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 22 km (14 mi) from the epicentre. In Berkeley, 3 km away, the estimate is intensity III (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: Berkeley 3 km, intensity III · Orinda 6 km, intensity III · Oakland 7 km, intensity III · El Cerrito 8 km, intensity II · Alameda 11 km, intensity II · Lafayette 11 km, intensity II · Richmond 12 km, intensity II · San Pablo 14 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 280 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.6 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 55,000× the energy of this one
- Magna, Utah 2020 M 5.7 39,000× the energy of this one
- Around the size people start to feel M 3.0 3.5× the energy of this one
- This earthquake M 2.6 about 280 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 4.5 on 2019-10-15 — about 540 times the energy of this one.
Before 2016, the USGS record lists 6 earthquakes of M5 or more within 50 km; the five largest:
- 7.9 The 1906 San Francisco, California Earthquake · 30 km WSW of this epicentre
- 6.0 The 2014 South Napa, California Earthquake · 39 km N of this epicentre
- 5.8 The 1980 Livermore, California Earthquake · 42 km E of this epicentre
- 5.4 9 km NE of Livermore, California · 49 km ESE of this epicentre
- 5.3 The 1957 San Francisco, California Earthquake · 30 km SW 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.
