Fault damage and healing processes from semblance analysis of waveforms generated by repeating earthquakes This project is focused on studying fault damage and healing processes in the San Andreas Fault zone associated with the nucleation of major earthquakes. Dr. Toteva is currently working with Iva Gerasimenko'10 and Sreya Bagchi'10 on a data set from Parkfield, CA. Parkfield is well known with its fairly regular magnitude 6.0 earthquakes. For that reason 15 years ago it was chosen to be the location of the SAFOD experiment. We are using semblance analysis to identify zones of high scattering along the Parkfield section of the San Andreas Fault. In particular, we are using data associated with the 2004 M6.0 Parkfield earthquake. |
This summer Archana is working on her internship at the Leibniz Institute of Marine Sciences at the University of Kiel, Germany. Archana Datta'09 is working on a 41 cm-long sediment core, strategically sampled from one of the topographical protrusions in the Fram Strait. The high sedimentation rates on the leeward side of these protrusions allow for a significantly higher temporal resolution. The aim of the study is to determine how temperature has evolved in Fram strait in the last 10,000 years. (More)
