Seismic-Hazard Maps for Alaska and the Aleutian Islands: PGA050

Probabilistic seismic hazard maps were prepared for Alaska portraying peak horizontal ground acceleration and horizontal spectral response acceleration for 0.2, 0.3, and 1.0 second periods with probabilities of exceedance of 10% in 50 years and 2% in 50 years. This particular data set is for peak horizontal acceleration with a 10% probability of exceedance in 50 years. All of the maps were prepared by combining hazard derived from spatially-smoothed historic seismicity with hazard from fault-specific sources. The acceleration values contoured are the random horizontal component. The reference site condition is firm rock, defined as having an average shear-wave velocity of 760 m/sec in the top 30 meters corresponding...

Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Paleoliquefaction locations observed in 1995 in Illinois

The northern part of the map area and large adjacent regions havebeen severely shaken by one or more moderate to large prehistoricearthquakes. The evidence of these takes the form ofpaleoliquefaction features, including shaking-induced sandblows anddikes that fed them.Over several summer field seasons from 1990 through 1994,several workers searched ditches and river banks for evidenceof liquefaction. They found numerous dikes and sandblows.This database includes the locations and descriptions of dikes theyobserved and measured.The most widespread paleoliquefaction is attributed to amid-Holocene earthquake near what is now Vicennes, IN, with anestimated moment- magnitude of about 7.5.

Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Locations of stress orientations

NOTE: Location of one point, near -88.65, 38.95, was incorrectwhen Sheet A was published. The location is .5 degree south, andis corrected in this dataset.This cover contains locations of places where greatest horizontalcompressive stress (S(Hmax)) orientations havebeen determined either by observation of well-bore breakouts or wherefocal mechanism solutions have been determined from earthquakes.Well-bore breakouts are observed from 0 to 1.4 km, whereas earthquakesgenerally occur deeper. The earthquake focal mechanismsshow both reverse and strike-slip faulting. Overall the stressindicators show easterly trending S(Hmax).

Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Seismograph Network station locations

This cover contains station locations of the New Madrid SeismicNetwork within the study boundary. The network is a cooperativeproject of Saint Louis University and Memphis State University.Operation of the network has been continuous since June 1975, butoperators have changed the network configuration throughout thattime period. The start and stop dates in the point attribute fileare not complete, but are included because they are useful for someof the stations.

Seismotectonic maps in the vicinity of the lower Wabash Valley, Illinois, Indiana, and Kentucky - Digital Spatial Database: Paleoliquefaction surveys between 1990 and 1994 in Indiana

The northern part of the map area and large adjacent regions have been severely shaken by one or more moderate to large prehistoric earthquakes. The evidence of these takes the form of paleoliquefaction features, including shaking-induced sandblows and dikes that fed them. Over several summer field seasons between 1990 and 1994, Cheryl and Pat Munson, along with several of their students, searched ditches and river banks for evidence of liquefaction. They found numerous banks with shaking-induced sandblows and the dikes that fed them. This database includes the location of dikes that the Munsons and those with them observed and measured. Dike thickness was divided into 5 classes, 1 being the smallest at 0-4 cm,...

Seismic-Hazard Maps for Alaska and the Aleutian Islands: 3HZ250

Probabilistic seismic hazard maps were prepared for Alaska portrayingpeak horizontal ground acceleration and horizontal spectral responseacceleration for 0.2, 0.3, and 1.0 second periods with probabilitiesof exceedance of 10% in 50 years and 2% in 50 years. This particulardata set is for horizontal spectral response acceleration for 0.3 secondperiod with a 2% probability of exceedance in 50 years. All ofthe maps were prepared by combining hazard derived from spatially-smoothed historic seismicity with hazard from fault-specific sources.The acceleration values contoured are the random horizontal component.The reference site condition is firm rock, defined as having an averageshear-wave velocity of 760 m/sec in the...
