description George Plafker Overview
George Plafker was a geologist with the United States Geological Survey (USGS) who specialized in earthquake geology and tectonics. He is most famous for his extensive field investigations immediately following the 1964 Alaska Good Friday earthquake, where he meticulously mapped the dramatic vertical land shifts across the region. His observational data provided crucial evidence that megathrust earthquakes occur at subduction zones, fundamentally advancing the scientific understanding of plate tectonics. Plafker also conducted significant research on seismic hazards across the Caribbean and the Pacific Rim.
