Deformation across the rupture zone of the 1964 Alaska earthquake, 1993–1997 Deformation across the rupture zone of the 1964 Alaska earthquake, 1993–1997
A linear array of 15 geodetic monuments was installed in 1993 across the rupture zone of the 1964 Alaska earthquake (Mw = 9.2). The array extends from Middleton Island (at the edge of the continental shelf and 80 km from the Alaska‐Aleutian trench) to north of Palmer, Alaska (380 km from the trench), in the approximate direction of Pacific‐North American plate convergence (N15.5°W). The...

Weakness of the lower continental crust: A condition for delamination, uplift, and escape Weakness of the lower continental crust: A condition for delamination, uplift, and escape
We discuss three interconnected processes that occur during continental compression and extension: delamination of the lower crust and sub-crustal lithosphere, escape tectonics (i.e., lateral crustal flow), and crustal uplift. We combine calculations of lithospheric viscosity–depth curves with geologic observations and seismic images of the deep crust to infer the mechanisms controlling...

Migration of fluids beneath Yellowstone caldera inferred from satellite radar interferometry Migration of fluids beneath Yellowstone caldera inferred from satellite radar interferometry
Satellite interferometric synthetic aperture radar is uniquely suited to monitoring year-to-year deformation of the entire Yellowstone caldera (about 3000 square kilometers). Sequential interferograms indicate that subsidence within the caldera migrated from one resurgent dome to the other between August 1992 and August 1995. Between August 1995 and September 1996, the caldera region...

Geologic controls on the formation of lakes in north-central Florida Geologic controls on the formation of lakes in north-central Florida
Fluid exchange between surficial waters and groundwater, as well as the processes that control this exchange, are of critical concern to water management districts and planners. Digital high-resolution seismic systems were used to collect geophysical data from 30 lakes of north-central Florida. Although using seismic profile data in the past has been less than successful, the use of...

Seasonal variation in habitat use by marsh fishes Seasonal variation in habitat use by marsh fishes
We used I-m2 throw traps to examine habitat use by smallsized fishes within a mosaic of wet prairies and sloughs in the headwaters of the St. Johns River, Florida between August 1992 and November 1995. Estimates of total fish density and biomass varied temporally, but did not differ significantly between habitats. Patterns of habitat use, however, differed among the five numerically...

Suppression of large earthquakes by stress shadows: A comparison of Coulomb and rate-and-state failure Suppression of large earthquakes by stress shadows: A comparison of Coulomb and rate-and-state failure
Stress shadows generated by California's two most recent great earthquakes (1857 Fort Tejon and 1906 San Francisco) substantially modified 19th and 20th century earthquake history in the Los Angeles basin and in the San Francisco Bay area. Simple Coulomb failure calculations, which assume that earthquakes can be modeled as static dislocations in an elastic half-space, have done quite...
