photo 1: Geologist Wes Wallace of the University of Alaska’s Geophysical Institute took this photo of the Denali Fault before the earthquake. The red line represents the fault, which runs east toward Mt. Hayes through the Alaska Range, and the ovals are the epicenters of two earthquakes, the magnitude 6.7 earthquake of Oct. 23, 2002, and the Denali Fault earthquake of Nov. 3, 2002. Wes Wallace photo

photo 2: USGS glaciologist Dennis Trabant took this composite photo of rock avalanches that occurred on upper Black Rapids Glacier during the earthquake. This photo, two images stitched together by the USGS’s Rod March, shows a view looking west toward the divide of Black Rapids and Susitna glaciers. Dennis Trabant photo.
