This dataset contains information and locations on faults and associated folds in Alaska that are believed to be sources of M>6 earthquakes during the Quaternary (the past 1,, years). The dataset is intended to part of the USGS archive for historic and ancient earthquake sources used in current and future probabilistic seismic-hazard analyses. The Greys River fault is the easternmost active normal fault associated with Basin and Range extension in the lntermountain seismic belt. It is a north south trending normal fault, located in the Sevier-age fold and thrust belt of western Wyoming, and bounds the west side of the Wyoming Range. The fault is at least 54 km long, and juxtaposes Permo-Pennsylvanian Wells Formation against Cited by: 1.

Mickey Springs in the Alvord Desert, southeast Oregon, is analogous to other Basin and Range hydrothermal systems where the requisite conditions of heat source and permeable pathways are met through crustal thinning due to normal faulting.

Through study on trenches, analysis of recurrence characteristics and recurrence interval cluster/gap of strong earthquakes along the major active faults on the northern border of Ordos block, we found 62 paleoearthquakes that occurred in the late Quaternary, including Cited by: 3.

Jul 17, · This publication is an updated active fault map for central and eastern Oregon. An Update of Quaternary Faults of Central and Eastern Oregon By R.J.
Weldon, II 1, D.K. Fletcher 1, E.M. Weldon 1, K.M. Scharer 1, and P.A. McCrory 1. A literature search was undertaken to update the catalog of active faults in central and eastern Oregon. Those studies published in the past decade are listed in the references (see 'Read-Me' file) and in the ArcInfo database as attributes to the fault traces.
This is the online version of a CD-ROM publication. We have updated the eastern portion of our previous active fault map of Oregon (Pezzopane, Nakata, and Weldon, ) as a contribution to the larger USGS effort to produce digital maps of active faults in the Pacific Northwest region.
Many faults are mapped as individual segments across an area. These fault segments are given a different value for name, number, code, or dip direction and so in the database each segment occurs as its own unique entity. For example, the San Andreas Fault has several fault segments, from letters a to h, and fault segment 1h has segments with age of last fault movement from.

Synchronous late Pleistocene extensional faulting and basaltic volcanism at Four Craters Lava Field, central Oregon, USA Although central Oregon has many Quaternary volcanic features, few have absolute ages.
An update of Quaternary faults of central and eastern Oregon:Cited by: 1. Latest Pleistocene and Holocene fault activity in Oregon concentrates along four zones that splay northward from seismically active faults along the Central Nevada and Eastern California seismic zones.
The Central Oregon fault zone is one of these zones, which splays northward from dextral faults of the Walker Lane, stretching across the flanks. An active fault is a fault that is likely to become the source of another earthquake sometime in the future. Geologists commonly consider faults to be active if there has been movement observed or evidence of seismic activity during the last 10, years.
Quaternary stratigraphic relations and exploratory trenching in zones of historical surface faulting in the western Basin and Range Province suggest that faults with historical surface ruptures have similar, and in some cases lower, long-term (late Quaternary) and short-term (Holocene) slip rates than other adjacent and regional non-historical.

Oct 02, · This book is the last of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale.
