Subduction II: SumatraOutline of this lecture • Reminder of coral microatolls • 1935 earthquake (microatolls) • 1833 earthquake (microatolls) • 2004 earthquake (coseismic and post seismic from GPS) • Supercycles on the Sumatran interface

Coral Microatolls: natural geodesy Porites coral grows in annual rings, much like a tree. It prefers to be just below the sea surface. http://www.tectonics.caltech.edu/outreach/highlights/sumatra/coral.html

Cross section of a Porites coral along with the resulting analysis of uplift and subsidence The large yellow arrows in the lower panel point to small emergences due to three distant giant earthquakes (1797, 1833, and 1861; >M8.5), as well as a large emergence due to a local large earthquake (1935; M7.7).
