Seismic Swarm S20160411.1: Analysis of Activity Near Hawthorne, Nevada

Seismic swarm S20160411.1 was recorded 19 km south of Hawthorne, Nevada, commencing at 15:57 on 10 April 2016 and concluding at 04:42 on 13 April 2016. Over a span of 60 hours and 44 minutes, the sequence comprised 51 earthquakes. Event magnitudes ranged from -0.3 to 1.3, with the majority falling below 1.0. Focal depths clustered between 5 km and 11 km, indicating shallow crustal activity typical of the local tectonic regime.

This swarm exemplifies clustered seismicity without a dominant mainshock, a pattern frequently observed in the region. The initial events on 10 April included magnitudes of 0.5, 1.3, and 0.6, followed by numerous micro-earthquakes through 12 April. Activity tapered on 13 April with final recordings of 0.9 and 0.1. Such sequences often arise from fluid migration along fault networks or stress redistribution within fractured rock, consistent with extensional tectonics prevalent in western Nevada.

Hawthorne lies within the Basin and Range Province, where crustal extension along north-trending normal faults drives recurrent seismic episodes. The locale forms part of the Walker Lane belt, a zone of distributed shear accommodating Pacific-North America plate motion. Historical records document persistent low-magnitude activity, with fault systems such as those bounding the Excelsior Mountains contributing to swarm occurrence.

Since 1 January 2000, 24 swarms have been identified in the area. Yearly tallies include one in 2001, three in 2006, eight in 2011, one in 2012, one in 2013, four in 2014, four in 2015, and two in 2016. This distribution underscores episodic clustering rather than isolated large events, reflecting the region's capacity for diffuse strain release.

The modest magnitudes in S20160411.1 produced no reported surface rupture or significant ground shaking. Depths averaging near 8 km align with brittle failure in the upper crust, where temperatures permit stick-slip behavior. Continued monitoring supports hazard assessment, as swarm recurrence informs probabilistic models for the Mineral County vicinity.
