Techniques in Active Tectonic Study - June 20-July 2, 2013

Join Prof. J. Ramon Arrowsmith from Arizona State University (ASU) for a training workshop on active tectonic study techniques. The workshop will include lectures, field trips, and hands-on activities around the Lembang Fault in West Java. Don't miss this opportunity to expand your knowledge in earthquake cycle exploration using 2D dislocations.

  2. Earthquake cycle exploration using 2D dislocations: strike-slipOutline of this lecture • Motivations from the San Andreas Fault • Basic ideas of dislocations • Strike-slip parallel displacements from simple screw dislocation model (Thatcher, 1990) • A few examples • Application to Izmit Earthquake

  3. Areas of contrasting behavior along the San Andreas Fault (from Allen, 1968) Carrizo Plain

  4. 1906 M7.8 San Francisco EarthquakeBeginning of modern earthquake science
