Development of surface ruptures by hanging-wall extension over a thrust ramp along the Ragged Mountain fault, Katalla, Alaska, USA: Applications of high-resolution three-dimensional terrain models
Autor: Terry L. Pavlis, Ronald L. Bruhn, Sarah N. Heinlein
Publikováno v: Geosphere. 17:582-601
High-resolution three-dimensional terrain models are used to evaluate the Ragged Mountain fault kinematics (Katalla, Alaska, USA). Previous studies have produced contradictory interpretations of the fault’s kinematics because surface ruptures along

Late Pleistocene Record of Off‐Fault Deformation and Vertical Slip Rates from the Wasatch Fault Zone, Utah: Implications for Fault Segmentation from Lake Bonneville Shorelines
Autor: Paul W. Jewell, Julia Corbett Howe, Ronald L. Bruhn
Publikováno v: Bulletin of the Seismological Society of America. 109:2198-2215
In an effort to better understand the Pleistocene history of the Wasatch fault zone, we evaluate the deformation and displacement of the Bonneville and Provo high‐stand shorelines of Lake Bonneville along the Wasatch Front. We apply an automated sh

Tectonic geomorphology and late Quaternary deformation on the Ragged Mountain fault, Yakutat microplate, south coastal Alaska
Autor: James P. McCalpin, Francisco Gutiérrez, Jesús Guerrero, Pedro Lucha, Terry L. Pavlis, Ronald L. Bruhn
Publikováno v: Geomorphology. 351:106875
The 33 km-long Ragged Mountain fault (RMF) forms the northwestern corner of the Yakutat Terrane, which is colliding with the North American plate in south coastal Alaska at ∼5.5 cm/yr. The fault zone contains three types of scarps in a zone up to 1

Outcrops and well logs as a practicum for calibrating the accuracy of traveltime tomograms
Autor: Sherif M. Hanafy, Shengdong Liu, Ronald L. Bruhn, Ann Mattson, Gerard T. Schuster
Publikováno v: Interpretation. 3:SY27-SY40
We have developed two case studies demonstrating the use of high-resolution seismic tomography and reflection imaging in the field of paleoseismology. The first study, of the Washington fault in southern Utah, USA, evaluated the subsurface deposits i

Salt-dissolution faults versus tectonic faults from the case study of salt collapse in Spanish Valley, SE Utah (USA)
Autor: Francisco Gutiérrez, James P. McCalpin, Jesús Guerrero, Grant Willis, Ronald L. Bruhn, Morteza Mozafari
Publikováno v: Lithosphere. 7:46-58
A paleoseismological investigation in Spanish Valley, SE Utah, reveals that faults related to interstratal karstification of salt may show episodic displacement and significantly different parameters than tectonic faults. Spanish Valley is a 25-km-lo

Ice surface morphology and flow on Malaspina Glacier, Alaska: Implications for regional tectonics in the Saint Elias orogen
Autor: Richard R. Forster, Ronald L. Bruhn, Michelle M. Cotton, E. W. Burgess, Jeanne Sauber
Publikováno v: Tectonics. 33:581-595
The Saint Elias Mountains in southern Alaska are located at a structural syntaxis where the coastal thrust and fold belt of the Fairweather plate boundary intersects thrust faults and folds generated by collision of the Yakutat Terrane. The axial tra

Effects of bedrock lithology and subglacial till on the motion of Ruth Glacier, Alaska, deduced from five pulses from 1973 to 2012
Autor: Dorothy K. Hall, James Turrin, Ronald L. Bruhn, Jeanne Sauber, Richard R. Forster
Publikováno v: Journal of Glaciology. 60:771-781
A pulse is a type of unstable glacier flow intermediate between normal flow and surging. Using Landsat MSS, TM and ETM+ imagery and feature-tracking software, a time series of mostly annual velocity maps from 1973 to 2012 was produced that reveals fi

Late Holocene great earthquakes in the eastern part of the Aleutian megathrust
Autor: Natasha L. M. Barlow, Emma P. Hocking, Kelly Good, Ronald L. Bruhn, Ian Shennan
Publikováno v: Quaternary science reviews, 2014, Vol.84, pp.86-97 [Peer Reviewed Journal]
The great earthquake, Mw 9.2, of AD 1964 may not be typical of other megathrust earthquakes in the region during the last 4000 years. We present new field data from three sites: Copper River Delta, the lower Katalla River valley and Puffy Slough, to
