Constraining the Slip Distribution and Fault Geometry of the Mw 7.9, 3 November 2002, Denali Fault Earthquake with Interferometric Synthetic Aperture Radar and Global Positioning System Data
The Mw 7.9, Denali fault earthquake (DFE) is the largest continental strike-slip earthquake to occur since the development of Interferometric Synthetic Aperture Radar (InSAR). We use five interferograms, constructed using radar images from the Canadian Radarsat-1 satellite, to map the surface deformation at the western end of the fault rupture. Additional geodetic data are provided by displacem...
متن کاملSource model for the Mw 6.7, 23 October 2002, Nenana Mountain Earthquake (Alaska) from InSAR
[1] The 23 October 2002 Nenana Mountain Earthquake (Mw 6.7) occurred on the Denali Fault (Alaska), to the west of the Mw 7.9 Denali Earthquake that ruptured the same fault 11 days later. We used 6 interferograms, constructed using radar images from the Canadian Radarsat-1 and European ERS-2 satellites, to determine the coseismic surface deformation and a source model. Data were acquired on asce...
متن کاملRemotely Triggered Seismicity on the United States West Coast following the Mw 7.9 Denali Fault Earthquake
The Mw 7.9 Denali fault earthquake in central Alaska of 3 November 2002 triggered earthquakes across western North America at epicentral distances of up to at least 3660 km. We describe the spatial and temporal development of triggered activity in California and the Pacific Northwest, focusing on Mount Rainier, the Geysers geothermal field, the Long Valley caldera, and the Coso geothermal field...
متن کاملSeismicity in Idaho and Montana Triggered by the Denali Fault Earthquake: A Window into the Geologic Context for Seismic Triggering
We present a case study of dynamically triggered seismicity in Idaho and western Montana from the 2002 MW 7.9 Denali fault earthquake to investigate the relationship between measured geological discriminants and propensity for triggering. We first establish triggering. We find events that are not reported in the Advanced National Seismic System catalog in Idaho and Yellowstone following the Den...
متن کاملDetecting co-seismic displacement in glaciated regions: An example from the great November 2002 Denali earthquake using SPOT horizontal offsets
We use SPOT image pairs to determine horizontal offsets associated with the Mw 7.9 November 2002 Denali earthquake in the vicinity of Slate Creek, AK. Field measurements and aerial photographs are used to further characterize the geometry of the surface rupture. Aerial photographs show that shear localization occurs where the rupture trace is linear, and distributed off-fault deformation is com...
