Subsidence

Two sketches and one photograph showing the process of subsidence and ghost forest formation during the 1964 Great Alaska Earthquake. One sketch shows pre-earthquake conditions with Sitka spruce and hemlock trees above a beach shoreface. The other sketch shows post-earthquake conditions with post-earthquake subsidence, landward retreat of the beach escarpment and standing dead trees and stumps now in the surf zone.
