Use the topographic map and the pyroclastic flow layers to find the relief from summit to the farthest extent of the 100-year lahar flow. How far does the pyroclastic flow extend from the summit? What is the lowest elevation that is covered by potential pyroclastic flow?
What will be an ideal response?
The 100-year lahar extends to the Port of Tacoma, therefore the relief is 14410’. The pyroclastic flow extends 18 km to the southwest anddown to the 2160’ contour along the Nisqually River.
