We have conducted a paleoseismic investigation of serial fault rupture at one site along the 110-km rupture of the North Anatolian fault that produced the Mw 7.4 earthquake of 17 August 1999. The benefit of using a recent rupture to compare serial ruptures lies in the fact that the location, magnitude, and slip vector of the most recent event are all very well documented. We wished to determine...

New geologic mapping, morphologic fault scarp modeling, and geomorphic metrics in the Red Rock Valley, southwestern Montana, help characterize the Quaternary history of the virtually unstudied Monument Hill fault and tectonics of the youthful and seismically active Red Rock graben. Two generations of Pleistocene surface ruptures are preserved along the Monument Hill fault. Similarity in rupture...

[1] Before the launch of the Lunar Reconnaissance Orbiter, known characteristics of lobate scarps on the Moon were limited to studies of only a few dozen scarps revealed in Apollo-era photographs within ~20 of the equator. The Lunar Reconnaissance Orbiter Camera now provides meter-scale images of more than 100 lobate scarps, as well as stereo-derived topography of about a dozen scarps. High-res...

PRIME Lab has a multidisciplinary external research program with projects in geomorphology, hydrology, ocean science, planetary science, environmental science and biology. Introduction PRIME Lab is a national AMS facility for measurement of the long lived cosmogenic nuclides Be, C, Al, Cl, Ca, and I [1]. Since its inception in 1991 we have chemically processed over 2000 samples and have measure...

Nearly horizontal sedimentary sequences are typically eroded into escarpments capped by resistant rock layers. These escarpments record in planform the spatial variation in erosional processes. Simulation models have been constructed of scarp development by three processes, scarp backwasting, fluvial erosion, and groundwater sapping, acting singly or in combination. Scarp backwasting produces p...

iran is one the most tectonically active parts of the world and regularly experiences earthquakes of both low and high magnitude. therefore, earthquake hazard assessment before any kind of building construction and for already built and populated area is essential. a vital first step in this type of study is to identify, map, and determine the activity of faults within a given region. investiga...

Triggered by reactivation of the strike-slip North Anatolian Fault, the disastrous Mw 7.4 Kocaeli (Turkey) earthquake also produced normal faulting in the pull-apart basin of Gölcük. Surface scarps from such faulting reached almost 2.5m in height. Several structures were crossed by the surface rupture. As expected, many of them either collapsed or were severely damaged. But, surprisingly, sever...
