Imaging Fault Damage Zones with Seismic and Geodetic Data - Elizabeth Cochran, Department of Earth Sciences, University of California, Riverside: During earthquakes slip is often localized on preexisting faults, but it is not well understood how the structure of crustal faults may contribute to slip localization and energetics. Growing evidence suggests that the crust along active faults suffers anomalous strain and damage during large quakes.

Not-So-Simple Cinder Cone Plumbing Systems: Examples From the Sierra Nevada - Brandon Browne, Department of Geological Sciences, California State University Fullerton: Cinder cones situated in continental monogenetic volcanic fields are generally thought to erupt single magma batches over short periods of time.

The Cretaceous-Paleogene ("KT") Boundary In Belize and Alabama - David T. King, Jr., Department of Geology and Geography, Auburn University, Alabama: Belize - At Albion Island in northern Belize, Cretaceous-Paleogene (KT) boundary deposits, also known as the Albion formation, rest upon karsted and fractured Maastrichtian dolostones. These deposits consist of a basal impactoclastic clay layer (~ 1 to 2-m thick) and an upper carbonate-rich, coarse impactoclastic breccia layer (up to 15-m thick). The focus of this paper is the upper layer, the Albion impactoclastic breccia.
