Seismographs logged a magnitude 2.8 earthquake 21 km SW of Pinehill, New Mexico with origin time 20:53 UTC on August 29, 2026. Coming 17 hours after a magnitude 3.4 earthquake in the immediate vicinity, it is most likely an aftershock of that larger rupture. This very shallow event was close enough to the surface that even modest magnitudes can produce significant local shaking. See the M2.8 event page for the full report, ShakeMap, and citizen-reported intensity data. | ||||||||
