Southwest Nevada Volcanic Field As An Upper Mantle Strain Marker

• Tomographic imaging indicates that little relative motion of the crust relative to the upper mantle has occurred in the last 15 Ma or more.
• Asthenospheric flow has been negligible to at least 250 km.

Applications of Bayesian Thinking to Radiocarbon Chronologies

• Stratigraphic information can sometimes be used to improve C14 dating precision.
  • Depositional ordering among samples.
  • Likely time separations among samples, as from a growth or accretion rate.
  • Historical constraints.
• Applications to date have improved paleoseismic event resolution on the southern San Andreas Fault.
• Work in Progress...

Site Effects and Kappa

• Site effects in the Yucca Mountain area of southern Nevada figure greatly in the seismic design of a potential repository.
• Current research involves interpreting the spectral rolloff of the abundant volume of well recorded small earthquakes of the area.
• (Presently anecdotal) evidence suggests that much of kappa is actually source related.
• Present and prospective research
