caption_attribution_description: English: Map of the Tacoma (WA) fault zone. Extract of figure 1 from Pratt, et al., "Field and laboratory data from an earthquake history study of scarps in the hanging wall of the Tacoma fault, Mason and Pierce Counties, Washington", U.S. Geological Survey Scientific Investigations Map 3060, 2008.
context_page_description: The Tacoma Fault, just north of the city of Tacoma, Washington, is an active east–west striking north dipping reverse fault with approximately 35 miles of identified surface rupture. It is believed capable of generating earthquakes of at least magnitude Mw 7, and there is evidence of such a quake approximately 1,000 years ago, possibly the same earthquake documented on the Seattle Fault 24 miles to the north.
