Slab2 - A Comprehensive Subduction Zone Geometry Model, Pamir Region

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 earthquake...

Risk-targeted maximum considered earthquake ground motion (MCER) of 1.0-second spectral response acceleration

A seismic hazard model for South America, based on a smoothed (gridded) seismicity model, a subduction model, a crustal fault model, and a ground motion model, has been produced by the U.S. Geological Survey. These models are combined to account for ground shaking from earthquakes on known faults as well as earthquakes on un-modeled faults. This data set represents the probabilisti

Risk-targeted maximum considered earthquake ground motion (MCER) of 0.2-second spectral response acceleration

A seismic hazard model for South America, based on a smoothed (gridded) seismicity model, a subduction model, a crustal fault model, and a ground motion model, has been produced by the U.S. Geological Survey.

Modified Mercalli Intensity based on peak ground acceleration, with a 10% probability of exceedance in 50 years

A seismic hazard model for South America, based on a smoothed (gridded) seismicity model, a subduction model, a crustal fault model, and a ground motion model, has been produced by the U.S. Geological Survey. These models are combined to account for ground shaking from earthquakes on known faults as well as earthquakes on un-modeled faults. This data set represents the results of c

0.2-second spectral response acceleration (5% of critical damping) with a 10% probability of exceedance in 50 years

Merged earthquake catalog without duplicates for the western U.S. (Catalog A inside UCERF3 zone and Catalog B outside UCERF3 zone)

A methodology has been developed at the U.S. Geological Survey (USGS) for making earthquake catalogs for seismic hazard analysis. A new catalog is assembled from several preexisting catalogs. Uniform moment magnitudes and related parameters for estimating unbiased seismicity rates are calculated. Duplicates, explosions, mining-related earthquakes, and induced earthquakes are flagged%

Bathymetric and topographic grid intended for simulations of the 1945 Makran tsunami in Karachi Harbour

This digital elevation model provides a tool for calibrating tsunami risk to observations of the 1945 Makran tsunami in Karachi Harbour. The DEM bathymetry is derived from soundings made mainly during the first eight years after the tsunami. Although deficient in portraying intertidal backwaters and upland topography, the DEM accurately depicts the sheltered setting of one of the two tide...

Hazard curve data for annual rate of exceedance versus 0.2-second spectral response acceleration

A seismic hazard model for South America, based on a smoothed (gridded) seismicity model, a subduction model, a crustal fault model, and a ground motion model, has been produced by the U.S. Geological Survey. These models are combined to account for ground shaking from earthquakes on known faults as well as earthquakes on un-modeled faults. This data set represents the hazard curve

Declustered catalog of induced earthquakes without duplicates for the central and eastern U.S.

A methodology has been developed at the U.S. Geological Survey (USGS) for making earthquake catalogs for seismic hazard analysis. A new catalog is assembled from several preexisting catalogs. Uniform moment magnitudes and related parameters for estimating unbiased seismicity rates are calculated. Duplicates, explosions, mining-related earthquakes, and induced earthquakes are flagged%

Chance of considerable (MMI = VIII) damaging earthquake shaking in 100 years

This data set portrays the spatial potential for damaging earthquake ground shaking quantified as considerable (MMI = VI) in 100 years. The maps and data are based on the average of the results obtained from peak ground acceleration and 1.0-second horizontal spectral acceleration. Site specific soil factors based on Vs30 shear wave velocities were implemented using a simple topographic pr...
