A 3D temperature model is constructed in order to support the estimation of physical parameters within the USGS National Crustal Model. The crustal model is defined by a geological framework consisting of various lithologies with distinct mineral compositions. A temperature model is needed to calculate mineral density and bulk and shear modulus as a function of position within the crust. These pro

We used matched filter detection and multiple-event relocation techniques to characterize the spatiotemporal evolution of the sequence. Our analysis is from the 14 closest seismic stations to the earthquake sequence, which included seven permanent stations from the Montana Regional Seismic Network, one permanent station from the ANSS backbone network and three temporary seismic stations deployed b

The 2018 Update of the U.S. National Seismic Hazard Model defines the potential for earthquake ground shaking for various probability levels across the conterminous United States and is applied in seismic provisions of building codes, insurance rate structures, risk assessments, and other public policy. The updated model represents an assessment of the best available science in earthquake hazards

This study involves a collection of peak ground motions from the 2018 M6.9 earthquake near Leilani Estates, Hawaii and the seismicity associated with the Kilauea Volcano eruption and summit collapse events. This study was intended to provide instrumental ground motion observations to evaluate ground motion models for use in the USGS Hawaii seismic hazard model. Significant variations in ground mot

We generated digital elevation models (DEMs) using pre- and post-event in-track stereo 0.5 m resolution panchromatic Worldview 1 and 2 images (2019, DigitalGlobe) using the Surface Extraction from TIN-based Searchspace Minimization (SETSM) software [Noh and Howat, 2015] running on the University of Iowa Argon supercomputer (Table S1). The post-event DEMs exhibit along-track striping artifacts comm

The dataset contains earthquake ground motions from intermediate-depth (in-slab) earthquakes occurring within 350 km of Anchorage, Alaska 2008-2019. Ground motions are processed as described in the accompanying journal article for rotation-independent horizontal-component ground-shaking at oscillator periods between 0.1 and 10 s.

These data are a summary of modeled exposure of various lifeline infrastructure linear features and facilities (transportation, water supply and wastewater, oil and gas, electric power, and telecommunications) to potential hazards resulting from the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, C

These data are a geospatial representation of potential damage resulting from fires following the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data take information about prevailing conditions (for example, average wind speed and direction) and potential hazard information (for example

Recent widespread seismicity in Oklahoma is attributed to the reactivation of pre existing, critically-stressed, and seismically unstable faults due to decades of wastewater injection. However, the structure and properties of the reactivated faults remain concealed by the sedimentary cover. Here, we explore the major ingredients needed to induce earthquakes in Oklahoma by characterizing basement f

Fault heterogeneities such as bumps, bends, and stepovers are commonly observed on natural faults but challenging to recreate under controlled laboratory conditions. We study deformation and microseismicity of a 76 mm-diameter Westerly granite cylinder with a sawcut fault with known frictional properties. An idealized asperity is added by emplacing a precision-ground 21 mm-diameter solid granite d
