Remote Single-Station Seismic Monitoring of the July–October 2022 Earthquake Swarm at Ta‘ū Volcano, American Samoa Open
From July to October 2022, a noneruptive volcanic earthquake swarm occurred within ∼15 km of Ta‘ū Island, located in eastern American Samoa. Felt reports from residents were the only available information about the swarm when it started, a…

Triggering the 2022 eruption of Mauna Loa Open
Distinguishing periods of intermittent unrest from the run-up to eruption is a major challenge at volcanoes around the globe. Comparing multidisciplinary monitoring data with mineral chemistry that records the physical and spatio-temporal …

An Unprecedented Experiment to Map Kīlauea’s Summit Magma System Open
Dozens of researchers deployed nearly 2,000 seismic stations—and a T-Rex—to better illuminate subsurface structure and magma storage below the summit of the highly active volcano.

Characterizing and Locating Seismic Tremor during the 2022 Eruption of Mauna Loa Volcano, Hawai’i, with Network Covariance Open
The 2022 eruption of Mauna Loa Volcano, Hawai’i, was accompanied by continuous seismic tremor that began about 30 min before and ended several days after the eruption. We characterize the amplitude history and frequency content of the trem…

Integrating Magnetotelluric and Seismic Images of Silicic Magma Systems: A Case Study From the Laguna del Maule Volcanic Field, Central Chile Open
Imaging silicic systems using geophysics is challenging because many interrelated factors (e.g., temperature, melt fraction, melt composition, geometry) can contribute to the measured geophysical anomaly. Joint interpretation of models fro…

Teleseismic Tomography of the Laguna del Maule Volcanic Field in Chile Open
With substantial postglacial rhyolite eruptions and ongoing rapid uplift, the Laguna del Maule volcanic field in the southern Andes provides an exceptional opportunity to study the dynamics of an active silicic magmatic system. Using 4,093…

Magma Reservoir Below Laguna del Maule Volcanic Field, Chile, Imaged With Surface‐Wave Tomography Open
The Laguna del Maule (LdM) volcanic field comprises the greatest concentration of postglacial rhyolite in the Andes and includes the products of ~40 km 3 of explosive and effusive eruptions. Recent observations at LdM by interferometric sy…

Inferring Magma Dynamics at Veniaminof Volcano Via Application of Ambient Noise Open
Ambient noise interferometry has become an increasingly popular tool for monitoring active volcanoes. We apply this method to investigate seven past eruptive periods at Veniaminof volcano, Alaska. Two of the largest eruptions studied show …

3-D<i>P</i>- and<i>S</i>-wave velocity structure and low-frequency earthquake locations in the Parkfield, California region Open
To refine the 3-D seismic velocity model in the greater Parkfield, California region, a new data set including regular earthquakes, shots, quarry blasts and low-frequency earthquakes (LFEs) was assembled. Hundreds of traces of each LFE fam…
