This was a moderate earthquake. Shaking at this size can damage poorly built structures close to the epicentre.
At this magnitude and depth, people at rest would likely notice it out to about 275 km (171 mi) from the epicentre. In Redwood Valley, 11 km away, the estimate is intensity V (moderate). 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: Willits 12 km, intensity V · Brooktrails 16 km, intensity V · Ukiah 24 km, intensity V · Upper Lake 35 km, intensity IV · Boonville 41 km, intensity IV · Laytonville 42 km, intensity IV · Lakeport 45 km, intensity IV · Covelo 48 km, intensity IV. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 3.7 kilotons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 6.6 would have released about 32 times as much.
- Northridge, California 1994 M 6.7 46× the energy of this one
- Mineral, Virginia 2011 M 5.8 2.1× the energy of this one
- Magna, Utah 2020 M 5.7 1.5× the energy of this one
- This earthquake M 5.6 about 3.7 kilotons of TNT
- Around the size people start to feel M 3.0 this one released 7,700× 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 (31 mi) since our catalogue begins in 2016. The previous largest was M 5.1 on 2016-08-10.
Before 2016, the USGS record lists one earthquake of M5 or more within 50 km:
- 5.2 6 km ESE of Talmage, California · 30 km SSE 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.
