This inventory was originally created by Gorum and others (2014) describing the landslides triggered by the M 7.9 Denali, Alaska earthquake that occurred on 3 November 2002 at 22:12:41 UTC. Care should be taken when comparing with other inventories because different authors use different mapping techniques. This inventory includes landslides triggered by a sequence of earthquakes rather than a single mainshock. Please check the author methods summary and the original data source for more information on these details and to confirm the viability of this inventory for your specific use. With the exception of the data from USGS sources, the inventory data and associated metadata were not acquired by the U.S. Geological...

The Atlas of ShakeMaps (~14,100 earthquakes, 1900-2020) provides a consistent and quantitative description of the distribution of shaking intensity for calibrating earthquake loss estimation methodologies, like those used in the USGS Prompt Assessment of Global Earthquakes for Response (PAGER) system. Version 4 of the Atlas includes a vastly expanded compilation of ShakeMaps for consequential and widely felt earthquakes using updated ShakeMap (Version 4) software. For each event, we have attempted to gather available macroseismic, recorded ground motions and finite fault inputs. AtlasCat is the companion catalog to Atlas V4. For each event in the Atlas, AtlasCat contains population exposure to each intensity level,...

Seismicity catalogs, gridded seismic hazard curve data, gridded ground motion data, and mapped gridded ground motion values are available for the 1996 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 ground acceleration (PGA) and 0.1, 0.2, 0.3, 0.5, 1.0 and 2.0 second spectral acceleration at probability levels of 2 percent in 50 years (annual probability of 0.000404), 5 percent in 50 years (annual probability of 0.001026), and 10 percent in 50 years (annual probability of 0.0021), assuming firm rock soil conditions at 760 m/s, are...

The dataset comprises information about the magnitudes, distances and periods of ground motion measurements from an analysis of earthquake ground motions from induced events in Oklahoma and Kansas. The data set also includes ground motion residuals from comparing earthquake ground shaking with commonly used models for predicting ground motions in the U.S.

Subduction zones are home to the most seismically active faults on the planet. The shallow megathrust interface of subduction zones host our largest earthquakes, and are the only faults capable of M9+ ruptures. Despite these facts, our knowledge of subduction zone geometry - which likely plays a key role in determining the spatial extent and ultimately the size of subduction zone earthquakes - is incomplete. Here we calculate the three- dimensional geometries of all active global subduction zones. The resulting model - Slab2 - provides for the first time a comprehensive geometrical analysis of all known slabs in unprecedented detail.

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 acceleration at a probability level of 1 percent in 1 year (annual probability of 0.0101), assuming firm rock soil conditions at 760 m/s, are available. Hazard was calculated on a 0.05 degree by 0.05 degree grid, defined by a bounding box encompassing the central and eastern U.S. (-115 to -65 degrees longitude west, 24.6 to 50 degrees...
