IGPP graduate student Bettina Allmann wins AGU Outstanding Student Paper Award

IGPP graduate student Bettina Allmann was awarded an Outstanding Student Paper Award at the American Geophysical Union at the 2007 Fall Meeting in San Francisco, California.

Her oral presentation was recognized as among the best of a strong group of student presenters, setting an example for fellow students and the entire AGU membership. Bettina's presentation was titled "A High-Frequency Secondary Event During the 2004 M6.0 Parkfield Earthquake " and consisted of 3–D rupture imaging of the 2004 M6.0 Parkfield earthquake using a waveform back-projection method.

Bettina and her advisor, Professor Peter Shearer, located a distinct secondary high-frequency phase that radiated from a point about ~13km northwest of the hypocenter. Together with existing slip model inversions of the Parkfield earthquake, these results constrain several physical properties of the rupture process.
