Scarps mapped on 1m lidar data along Crowleys Ridge
This dataset provides line work of fault, fold, and unknown scarps mapped along the margins of Crowleys Ridge in the New Madrid seismic zone, Arkansas and Missouri.
Location of AEM lines across Crowleys Ridge
This dataset provides location information for the airborne electromagnetic (AEM) lines across Crowleys Ridge in the New Madrid seismic zone, central US. The AEM data are interpreted and discussed in the associated publication
Revised fault network for New Madrid seismic zone
This dataset provides line work of an interpreted revised fault network in the New Madrid seismic zone, central United States.
Data Release for the 2010 Haiti Seismic Hazard Model
Gridded seismic hazard curve data, gridded ground motion data, and mapped gridded ground motion values are available for the 2010 Haiti Seismic Hazard Model. Probabilistic seismic hazard data and maps are available for peak ground acceleration (PGA) and 0.2, and 1.0 second spectral acceleration at probability levels of 2 percent in 50 years and 10 percent in 50 years, assuming firm ro
High resolution earthquake catalogs from the 2018 Kilauea eruption sequence
The 2018 Kīlauea eruption and caldera collapse generated intense cycles of seismicity tied to repeated large seismic (Mw ~5) collapse events associated with magma withdrawal from beneath the summit. To gain insight into the underlying dynamics and aid eruption response, we applied waveform-based earthquake detection and double-difference location as the eruption unfolded. Here, we
A High-Resolution Seismic Catalog for the Initial 2019 Ridgecrest Earthquake Sequence
I use template matching and precise relative relocation techniques to develop a high-resolution earthquake catalog for the initial portion of the 2019 Ridgecrest earthquake sequence, from July 4-16, encompassing the foreshock sequence and the first 10+ days of aftershocks following the Mw 7.1 mainshock. Using 13,525 routinely cataloged events as waveform templates, I detect and precise
Data Release for Additional Period and Site Class Data for the 2018 National Seismic Hazard Model for the Conterminous United States (ver 1.1)
The updated 2018 National Seismic Hazard Model includes new ground motion models, aleatory uncertainty, and soil amplification factors for the central and eastern U.S. and incorporates basin depths from local seismic velocity models in four western U.S. (WUS) urban areas. These additions allow us, for the first time, to calculate probabilistic seismic hazard curves for an expanded set
