...Thomas M. Brocher; Margaret G. Hopper; S. T. Ted Algermissen; David M. Perkins; Stanley R. Brockman; Edouard P. Arnold Abstract Reported aftershock durations, earthquake effects, and other observations from the large 14 December 1872 earthquake in central Washington are consistent with an epicenter...

...Thomas M. Brocher; Richard J. Blakely; Brian L. Sherrod Abstract We investigate spatial and temporal relations between an ongoing and prolific seismicity cluster in central Washington, near Entiat, and the 14 December 1872 Entiat earthquake, the largest historic crustal earthquake in Washington...

... catostomids is critical to understanding the evolution of this fish group. We herein describe a new catostomid species of the genus † Amyzon Cope, 1872 from the Eocene Kishenehn Formation in Montana, USA. The new species, † Amyzon kishenehnicum , differs from known species of † Amyzon in having hypurals 2...

...Colin B. Amos; Andrew T. Lutz; Angela S. Jayko; Shannon A. Mahan; G. Burch Fisher; Jeffrey R. Unruh Abstract Recent upward revision of the 1872 Owens Valley earthquake from M w 7.4–7.5 to 7.7–7.9 implies either additional unrecognized rupture length or anomalously strong ground motions associated...

... in such environments. The samples are from the historical collection returned by the British HMS Challenger expedition (1872–1876) and kept at the Natural History Museum in London. The samples were collected from the vicinity of the Pacific–Antarctic Ridge and the Chile Ridge. The samples were analyzed by means of X...

...William H. Bakun Abstract 24 June 2008 Hough and Hutton (2008) have reconsidered macroseismic observations and geologic observations for the 1872 Owens Valley, California, earthquake. Their preferred moment magnitude M is 7.8–7.9, and they suggest that the 1872 Owens Valley...

... attenuation model of Bakun (2006) . In particular, Bakun (2009) argues that propagation effects can explain the relatively high intensities generated by the 1872 Owens Valley earthquake. Using an intensity attenuation model that attempts to account for attenuation through the Sierra Nevada, Bakun (2006...

...Susan E. Hough; Kate Hutton Abstract The 26 March 1872 Owens Valley earthquake is among the largest historical earthquakes in California. The felt area and maximum fault displacements have long been regarded as comparable to, if not greater than, those of the great San Andreas fault earthquakes...

...William H. Bakun; Ralph A. Haugerud; Margaret G. Hopper; Ruth S. Ludwin Abstract The largest historical earthquake in eastern Washington occurred on 15 December 1872. We used Modified Mercalli intensity (MMI) assignments for 12 twentieth-century earthquakes to determine attenuation relations...

...-1002 Ribbon Cliff Landslide, Washington, and the Earthquake of 14 December 1872 by Richard F. Madole, Robert L. Schuster, and Andrei M. Sarna-Wojcicki Figures 5 and 7 were incorrectly printed for this paper. The figures were printed in a way that the labels were not visible. Correct versions...

...Richard F. Madole; Robert L. Schuster; Andrei M. Sarna-Wojcicki Abstract Estimates of the epicentral location and maximum intensity of the earthquake of 14 December 1872, the largest and oldest historic earthquake documented in the Pacific Northwest, are controversial largely because the estimates...

...Dieter Weichert Abstract Omak Rock is an about 40-ton granite boulder balanced on a narrow support. The rock is located in northern Washington State, in the general vicinity of the 1872 Pacific Northwest M 7+ earthquake. The survival of the balanced rock has in the past been used to place limits...

...D. Fillion; R. K. Pickerill Abstract The poorly defined ichnofossil Arthraria antiquata Billings, 1872, is redescribed from its type location, Bell Island, eastern Newfoundland. Historically, the monospecific A. antiquata has been confused with and even placed into synonymy with the related...

... for all localities at which four or more earthquakes have been felt by averaging the difference between the computed intensity and reported intensity at each site. Using these correction factors, the intensities for the North Cascade earthquake of 1872 are used to place constraints on its size...

... of the Owens Valley earthquake of 1872 involved both dip-slip and right-lateral components of movement. The pattern of movement at Lone Pine in 1872 is opposed to the postulate of regionally systematic left-lateral movement along the east side of the Sierra Nevada during the Cenozoic, but does not prove...
