After 30 years in high-tech marketing and general management, Anne Sanquini began a second career as a PhD student at Stanford studying how to motivate people to take precautionary action to protect their homes and schools against earthquakes. Her work over the past four years led her to Kathmandu Valley in Nepal. She was there during the April 25 earthquake, the very quake she had been preparing for.

Four years after one of the largest earthquakes in recorded history devastated Japan, Stanford geophysicists Greg Beroza, Eric Dunham, and Paul Segall provide new insights that help clarify why previous assumptions about the fault had been so wrong.  Using new technologies, they explain what happened during the earthquake and tsunami, and discuss ongoing research that helps society better prepare for similar events in the future.
