- Abstract: Understanding of the processes by which earthquakes occur remains one of the great challenges of geophysics. The complex interplay among frictional processes, stress, pore fluid pressure, temperature, and other factors means that a comprehensive model for fault physics has not been achieved. One reason for this is the lack of in situ observations and samples from within the faults deep beneath the earth's surface. To address this problem, several major projects have been launched to drill into fault zones. The massive subduction earthquakes which occur at the boundary between two tectonic plates at subduction zones are especially of interest because they cause devastating tsunami, and occur with repeating characteristics. Off the Pacific coast of Japan, the NanTroSEIZE (Nankai Trough Seismogenic Zone Experiment) project targets a subduction zone for drilling to sample and place instruments into and around the fault zone responsible for these tsunami-generating earthquakes. Three-dimensional seismic reflection surveys image the plate boundary zone and provide evidence for fault properties. Drilling provides evidence on the rock composition, chemistry, stress, and other parameters. These unique new datasets are helping to test theoretical and laboratory-derived models for fault physics. I will discuss the overall challenge and present results from the first phase of drilling in 2007-2008.

Thursday, November 20th, 2008
- NPAC (Nuclear/Particle/Astro/Cosmo) Forum
- Prospects for High-Energy Cosmic Rays and Neutrinos from Gamma-Ray Bursts in the Swift/GLAST Era
- Time: 4:00 pm - 5:00 pm
- Place: 4274 Chamberlin
- Speaker: Kohta Murase, Kyoto University, Yukawa Institute
- Abstract: Gamma-ray burst (GRB) is one of the cosmic-ray acceleration sites,
and high-energy neutrino emission from GRBs has been expected in
various scenarios. Many predictions for prompt and afterglow emission were done in the pre-Swift era. Recently, Swift has shown several novel phenomena, which allows us to expect new possibilities for cosmic-ray acceleration and associated secondary particle emission. I will discuss cosmic-ray acceleration and neutrino emission in various scenarios of GRBs, motivated by recent observations and theoretical developments. The possible connection between ultra-high-energy cosmic rays (UHECRs) and GRBs will also be discussed. - Host: Teresa Montaruli
