  • The shallow quake struck just before 6 p.m. local time north-northeast of Indio at roughly 2 miles deep in a San Andreas Fault zone.
  • A 3.8 aftershock was recorded Tuesday morning, following multiple Monday evening aftershocks that included magnitude 3.4 and 3.3 events.
  • Riverside County Fire Department and Palm Springs police reported no confirmed injuries or structural damage following the shaking.
  • USGS logged thousands of felt reports across the region, early-warning alerts reached phones, and experts note a small (about 5%) short-term probability of a larger quake.
