The quake hit shortly after 7 p.m. and hit nearly 14.2 miles north-northeast from Barstow, according to the USGS. The depth of the shallow temblor was about 2.3 miles.
Six minutes later, a 2.9 aftershock struck the same area.
Seismologist Dr. Lucy Jones tweeted following the quake, saying that it was scientifically interesting as it occurred on an unmapped thrust fault.
Tonight's quake more scientifically interesting. M4.6 north of Barstow, ~halfway between 2019 Ridgecrest and 1992 Landers faults. 1947 M6.5 Manix quake was ~30 miles east of tonight's quake. Occurred on an unmapped thrust fault. Only Barstow seems to care— Dr. Lucy Jones (@DrLucyJones) January 25, 2020
People reported feeling the quake across a large swath of Southern California, including Lancaster, Fontana, Apple Valley and Glendale.
There were no immediate reports of injuries or damage.
