This was a light earthquake. It is usually felt clearly nearby and can rattle windows and dishes, but damage is uncommon.
At this magnitude and depth, people at rest would likely notice it out to about 164 km (102 mi) from the epicentre. In Ridgecrest, 34 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: Searles Valley 32 km, intensity III · Ridgecrest 34 km, intensity III. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 190 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.7 would have released about 32 times as much.
