Data

In November 2016, the U.S. Geological Survey acquired high resolution P- and S-wave seismic data across the trace of the West Napa Fault zone near Buhman Avenue in Napa, California. The primary goal of the seismic survey was to image the subsurface damage from the 2014 MW 6.0 South Napa earthquake to assist in a near-surface fault slip and deformation investigation. We acquired seismic...

In November 2016, the U.S. Geological Survey acquired high resolution P- and S-wave seismic data across the trace of the West Napa Fault zone in Saintsbury winery in Napa, California. The primary goal of the seismic survey was to image the subsurface damage from the 2014 MW 6.0 South Napa earthquake to assist in a near-surface fault slip and deformation investigation. We acquired seismic...

In September and October 2019, the USGS and UC Berkeley (UCB) deployed two nodal seismographs at the Byerly Seismographic Vault (station BRK), east of the UCB campus. One of the nodes was located immediately outside the vault, and the other was located within the vault, adjacent to a broadband seismometer. The objective of this deployment was to compare recordings of local earthquakes...

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 rock...

This data release contains two point clouds derived from structure-from-motion photogrammetry. The first survey was conducted on 10 September 2015 and the second survey was conducted on 1 June 2016. Each survey was designed to capture a 35-meter channel reach using digital photos (1187 photos were taken in the first survey and 1085 photos were taken in the second survey). Twenty-five...

This data release consists of Magnetic Repeat Station data collected at three different sites in the central United States. One site is in Fremont, NE, the other two are in Hereford and Del Rio, TX. Repeat Stations are temporary magnetic installations, where the Earth's magnetic field, or geomagnetic field, is measured for several days, with the goal of producing mean values of the...

This data release includes time-series data of rock temperature, air temperature, wind speed, and humidity at the Chalk Cliffs debris-flow monitoring site in central Colorado (Latitude: 38.73330, Longitude: -106.18704). The data were collected to help identify the environmental controls on rates of rockfall, which is the primary source of debris-flow material at the site. Data were...

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 precisely...

The 2018 Kilauea 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...

This project involves the compilation of ground motions, their derived parameters, and metadata for 133 earthquakes in the 2019 Ridgecrest, California, earthquake sequence. This dataset includes 22,991 records from 133 events from 4 July 2019 to 18 October 2019 with a magnitude range from 3.6 to 7.1.

Seismicity catalogs, gridded seismic hazard curve data, gridded ground motion data, and mapped gridded ground motion values are available for the 2016 One-Year Seismic Hazard Forecast for the Central and Eastern U.S. from Induced and Natural Earthquakes. Probabilistic seismic hazard data and maps of the conterminous U.S. for peak ground acceleration (PGA) and 0.2 and 1.0 second spectral...

Seismicity catalogs, gridded seismic hazard curve data, gridded ground motion data, and mapped gridded ground motion values are available for the 2002 National Seismic Hazard Model for the Conterminous U.S. Seismicity catalogs are available for the western U.S. (in Mw) and central and eastern U.S. (in mb). Probabilistic seismic hazard data and maps of the conterminous U.S. for peak...
