Bayesian inference elucidates fault-system anatomy and resurgent earthquakes induced by continuing saltwater disposal

An earthquake sequence in western Canada exhibits resurgent aftershocks, possibly in response to persistent, post-mainshock saltwater disposal. Here, we reduce uncertainty in mainshock source…

Previously hidden landslide processes revealed using distributed acoustic sensing with nanostrain-rate sensitivity

Landslides sometimes creep for decades before undergoing runaway acceleration and catastrophic failure. Observing and monitoring the evolution of strain in time and space is crucial to understand…

Crustal stress near the Yakutat microplate collision from probabilistic earthquake focal mechanisms

Earthquake source characteristics provide a valuable constraint on crustal stress and regional plate tectonics. Earthquake source studies in Yukon and northern British Columbia have been limited by…

Bayesian estimation of nonlinear centroid moment tensors using multiple seismic data sets

Centroid moment tensor (CMT) parameters of earthquakes are routinely estimated to gain information on structures and regional tectonics. However, for small earthquakes (M<4), it is still…

Earthquake Relocations Delineate a Discrete Fault Network and Deformation Corridor Throughout Southeast Alaska and Southwest Yukon

Deformation in southeastern Alaska and southwest Yukon is governed by the subduction and translation of the Pacific‐Yakutat plates relative to the North American plate in the St. Elias region.…

Range-dependent meso-scale geoacoustic seabed quantification.

This study presents a probabilistic one-step two-dimensional (2D) inversion method of spherical-wave reflection coefficient data to estimate the range-dependent structure and geoacoustic parameters…

Induced or Natural? Toward Rapid Expert Assessment, with Application to the Mw 5.2 Peace River Earthquake Sequence

Based on information available at the time, several questionnaire-based schemes have been developed to provide a qualitative assessment of whether a specific earthquake (or earthquake sequence) was…

Exploring for Offshore Freshened Groundwater: Integrated Geophysical Field Studies

Offshore freshened groundwater (OFG) may become increasingly of interest, particularly in densely populated coastal regions and on islands. The only physical parameter that changes with seafloor pore…
