The Yellowstone supervolcano is one of the largest active continental silicic volcanic fields in the world. An understanding of its properties is key to enhancing our knowledge of volcanic mechanisms and corresponding risk. Using a joint local and teleseismic earthquake P- wave seismic inversion, we unveil a basaltic lower- crustal magma body that provides a magmatic link between the Yellowstone mantle plume and the previously imaged upper- crustal magma reservoir.

This lower- crustal magma body has a volume of 4. These estimates are critical to understanding the evolution of bimodal basaltic- rhyolitic volcanism, explaining the magnitude of CO2 discharge, and constraining dynamic models of the magmatic system for volcanic hazard assessment.

Over the past several decades, the Yellowstone caldera has experienced frequent earthquake swarms and repeated cycles of uplift and subsidence, reflecting dynamic volcanic and tectonic processes. Here we examine the detailed spatial- temporal evolution of the 2. Madison Plateau swarm, which occurred near the northwest boundary of the Yellowstone caldera. To fully explore the evolution of the swarm, we integrated procedures for seismic waveform- based earthquake detection with precise double- difference relative relocation.

Using cross correlation of continuous seismic data and waveform templates constructed from cataloged events, we detected and precisely located 8. This high- resolution analysis reveals distinct migration of earthquake activity over the course of the swarm. The swarm initiated abruptly on 1. January 2. 01. 0 at about 1. NNW striking, ~5. To explain these characteristics, we hypothesize that the swarm was triggered by the rupture of a zone of confined high- pressure aqueous fluids into a preexisting crustal fault system, prompting release of accumulated stress.

The high- pressure fluid injection may have been accommodated by hybrid shear and dilatational failure, as is commonly observed in exhumed hydrothermally affected fault zones. This process has likely occurred repeatedly in Yellowstone as aqueous fluids exsolved from magma migrate into the brittle crust, and it may be a key element in the observed cycles of caldera uplift and subsidence. Smith, Published in Journal of Volcanology and Geothermal Research in 2. We evaluated properties of Yellowstone earthquake swarms employing waveform multiplet analysis. Thirty- seven percent of the earthquakes in the Yellowstone caldera occur in multiplets and generally intensify in areas undergoing crustal subsidence. Outside the caldera, in the Hedgen Lake tectonic area, the clustering rate is higher, up to 7.

The Yellowstone seismicity follows a succession of two phases of earthquake sequence. The first phase is defined between swarms. It is characterized by a decay of clustering rate and by foreshock- aftershock sequences. The second phase is confined to swarms and is characterized by an increase in clustering rate, and dominant aftershock sequences.

This phase reflects tectonic swarms that occur on short segments of optimally oriented faults. For example, the largest recorded swarm in Yellowstone occurred in autumn 1. Yellowstone Plateau which was initiated as a tectonic source sequence. Fitting experimental dependence of fluid injection with intrusion migration suggests that the 1. The 2. 00. 8- 2. 00. Yellowstone Lake swarm exhibited a high migration rate of 1 km/day, a decrease in clustering rate without a main- shock, and appears to be associated with magma injection of 1 to 5 m. The 2. 01. 0 Madison Plateau earthquake swarm on the west side of the caldera initiated as a tectonic sequence but the expansion of the swarm front was associated with hydrothermal fluid migration.

Hebgen Lake, MT, normal- faulting earthquake occurred in an extensional stress regime near the Yellowstone volcanic field. Time- dependent crustal deformation data following this major earthquake were acquired by precise trilateration and GPS surveys from 1. Hebgen Lake fault zone.

Modeling the changes of baseline lengths across and near the fault reveals a lateral variation of transient rheology, in which the lithosphere is stronger near the Hebgen Lake fault zone than in the vicinity of the Yellowstone volcano system. The models also imply that the lower crust is stronger than the upper mantle, in agreement with results from studies of postseismic and post- lake- filling relaxations (< ~1. In addition, evaluations of the postseismic motion produced by the Hebgen Lake and the 1.

Mw 6. 9 Borah Peak, ID, earthquakes indicate that horizontal transient motion of up to ~1 mm/yr contribute significantly to the contemporary regional crustal deformation near the epicentral areas. For the eastern Basin and Range, ~5. Hebgen Lake fault, similar rheologic models were derived from the observed uplift associated with the Lake Bonneville rebound and were used to evaluate the postseismic deformation associated with six most recent paleoearthquakes of the Wasatch fault zone and three M.
