Columbia River flood basalts from a centralized crustal magmatic system
The Columbia River Basalt Group in the northwestern United States, comprising about 230,000 cubic kilometres of rock, exhibits unusual patterns in lava distribution, geochemistry and its apparent relationship to regional tectonics. Consequently, there is little consensus on the origin of its magmas. Here, we examine the isotopic ratios of Sr, Nd, Pb and Os and traceelement abundances in Columbi...
متن کاملCoseismic Slip from the 6 October 2008, Mw6.3 Damxung Earthquake, Tibetan Plateau, Constrained by InSAR Observations
Coseismic deformation fields of the 6 October 2008 Mw6.3 Damxung earthquake were obtained from interferometric synthetic aperture radar by using three descending and two ascending Envisat images. Significant coseismic surface deformation occurred within 20 km 9 20 km of the epicenter with a maximum displacement of *0.3 m along the satellite line of sight. We model a linear elastic dislocation i...

15 صفحه اولQuantification of mass wasting volume associated with the giant landslide Maleh Kabood induced by the 2017 Kermanshah earthquake from InSAR
Radar sensors obtain regular and frequent radar images from which ground motion can be precisely detected using a variety of different techniques. The interferometric synthetic aperture radar (InSAR) is utilized to retrieve the spatial characteristics of the largest coseismic landslide Maleh-Kabood, induced by the Ms 7.3 Azgleh earthquake in Kermanshah Province, Iran. The available seven interf...
متن کاملAseismic slip transients emerge spontaneously in three-dimensional rate and state modeling of subduction earthquake sequences
[1] To investigate the possible physical mechanisms of recently observed aseismic slip events in the Cascadia, Japan and Mexico subduction zones, we apply a Dieterich-Ruina rate and state friction law to a three dimensional model of a shallow subduction fault. That is loaded by imposed steady plate slip rate far downdip along the thrust interface. Friction properties are temperature and hence d...
