Seismic Swarm S20240804.1: Earthquake Activity South of Whites City, New Mexico

Seismic swarm S20240804.1 occurred 55 km south of Whites City, New Mexico, from 04:00 on 3 August 2024 to 11:48 on 4 August 2024. Over 31 hours and 48 minutes, the swarm produced 26 earthquakes. Events were concentrated at shallow depths between 2 km and 8 km, with magnitudes ranging from 1.6 to 3.4.

The sequence began with a magnitude 2.1 event at 6 km depth. Subsequent activity included multiple events above magnitude 2.0 throughout 3 August, peaking with a magnitude 3.4 quake at 6 km depth at 17:24:28 UTC and a magnitude 3.3 event at 6 km depth at 18:35:24 UTC. Later events on 4 August remained below magnitude 3.0, concluding with a magnitude 1.6 quake at 7 km depth. Depths clustered around 5–6 km for most shocks, consistent with activity in the upper crust.

This swarm fits into a broader pattern of seismicity in southeastern New Mexico. The area lies within the Delaware Basin portion of the Permian Basin, underlain by thick Paleozoic sedimentary sequences. Regional tectonics reflect extension associated with the Rio Grande Rift system, though natural background seismicity remains moderate. Since 1 January 2000, 18 swarms have been recorded in the vicinity, distributed as one in 2022, twelve in 2023, and five in 2024. These episodes often feature similar shallow focal depths and rapid onset followed by decay within one to two days.

The 2024 swarm adds to evidence of episodic clustered seismicity. Magnitudes stayed below levels that typically cause damage, yet the concentration of events over a short interval distinguishes it from isolated tectonic earthquakes. Depths indicate rupture within or near sedimentary layers rather than deeper basement rock.

Ongoing monitoring continues to track activity in the Delaware Basin, where both natural faulting and fluid-related processes can influence event rates. The S20240804.1 sequence provides additional data for understanding swarm dynamics in this geologic setting.
