Seismic imaging and wave scattering in zones of random heterogeneity
Most current interpretations of lower crustal seismic reflectivity suggest the existence of fine-scale ($\approx$100 m thick) layered structures at depth. Typical common-midpoint (CMP) stacked images of deep structures ...
A FINITE-ELEMENT MODEL OF LUNAR THERMAL EVOLUTION
An attempt is made to model the thermal history of a self-gravitating Moon. Since the Rayleigh number at the end of the accretionary stage is supercritical, thermal convection in the Moon is likely to have occurred as early ...
The effect of caustics in acoustic inverse scattering experiments
Most inversion techniques described in the literature rely on the validity of ray tracing, which breaks down in the presence of caustics. The linearized acoustic inverse problem with constant reference velocity is analyzed ...
Source-velocity identification for a layered model of reflection seismology
The identification of the source signature is a major calibration problem in reflection seismology. Conventional approaches to this problem involve statistical methods, direct measurement of the source, or the location of ...
Crustal structure and tectonic evolution: Central California
Vertical incidence and wide angle seismic data suggest the central California transform margin is underlain at depth by a horizontal detachment surface above which strike-slip and compression occur. The boundary between ...
