Seismic Swarm S20150604.1: Analysis of Activity Near Goldfield, Nevada

A seismic swarm designated S20150604.1 occurred approximately 40 km south-southeast of Goldfield in Esmeralda County, Nevada. The sequence began at 23:53 UTC on 3 June 2015 and concluded at 10:07 UTC on 6 June 2015, spanning 58 hours and 14 minutes. During this interval, 48 earthquakes were recorded.

Magnitudes ranged from -0.1 to 2.4, with the majority falling between 0.2 and 1.0. The largest event reached magnitude 2.4 at 21:20 UTC on 4 June. Depths clustered primarily between 10 km and 18 km, although several shallower events occurred between 0 km and 7 km. Activity showed temporal clustering, with notable bursts on 4 June around 17:51–21:55 UTC and on 6 June near 08:30–10:07 UTC. These patterns are characteristic of swarm behavior, in which events occur in rapid succession without a single dominant mainshock.

The Goldfield region lies within the Basin and Range Province of western Nevada, an area defined by active crustal extension along north- to northwest-striking normal faults. This tectonic regime produces distributed seismicity and occasional earthquake swarms. The local geology features Tertiary volcanic rocks and associated epithermal mineral deposits that have historically supported gold and silver mining. Seismic swarms in this setting commonly reflect fluid migration or aseismic slip along fault networks rather than large-magnitude rupture.

Historical records indicate 11 swarms in the same area since 1 January 2000. These occurred in 2000, 2001, 2002, 2006, 2007 (two events), 2010, 2011 (two events), 2012, and 2015. The recurrence demonstrates persistent low-level tectonic strain release in the vicinity.

The 2015 swarm remained well below thresholds for felt shaking or damage in nearby communities. Continued monitoring by regional seismic networks supports ongoing assessment of strain accumulation along regional faults.
