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 11 km (7 mi) from the epicentre. In Livermore, 18 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.

How big was it?

This earthquake released about 10 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.7 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 1,500,000× the energy of this one
Magna, Utah 2020 M 5.7 1,000,000× the energy of this one
Around the size people start to feel M 3.0 92× the energy of this one
This earthquake M 1.7 about 10 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

No earthquake of M4 or more has been recorded within 50 km since our catalogue begins in 2016.

Before 2016, the USGS record lists 11 earthquakes of M5 or more within 50 km; the five largest:

6.5 Near Morgan Hill, California · 48 km S of this epicentre Jul 1, 1911
6.2 Near San Jose, California · 30 km SSW of this epicentre Aug 3, 1903
6.2 The 1984 Morgan Hill, California Earthquake · 26 km S of this epicentre Apr 24, 1984
6.1 Near San Jose, California · 40 km SSW of this epicentre Jun 11, 1903
5.8 The 1980 Livermore, California Earthquake · 35 km NNW of this epicentre Jan 24, 1980

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.
