From fishnet stockings to falling apples: Earthquake interactions on the scale of a fault to the planet
- Date & Time
- Building 3, Rambo Auditorium
Ross will use QuakeCaster and Fishnet Stocking Stress, demonstration tools he developed with students, to probe the fundamental riddle of earthquakes: why quakes are sporadic when their driving forces are steady. The demo also shows how earthquakes converse by the transfer of static and dynamic stress, an insight that helps crack the difficult problem of earthquake forecasting. Ross will then delve into the strange world of earthquake triggering and inhibition. He will argue that while most earthquakes interact over distances of a few fault rupture dimensions, rarely, megaquakes can engulf the entire globe in large aftershocks for days to a week.
