Surveying the Fairweather Fault trace
USGS Geologist Adrian Bender surveys a trace of the 1958 Fairweather Fault earthquake surface rupture. The trace forms a linear, uphill-facing, 1-2 m tall escarpment flanked by trees that were likely tilted during the 1958 earthquake. Location: Crillon Lake, Glacier Bay National Park, Alaska.

Fairweather Fault

Nearly 60 years after a magnitude 7.7 earthquake struck Lituya Bay, Alaska — leading to a tsunami that devastated the area — six U.S. Geological Survey geologists revisited the isolated region of Alaska, to pick up where their scientific predecessors left off.
