ACTIVE TECTONICS OF THE SEATTLE FAULT AND CENTRAL PUGET SOUND, WASHINGTON — IMPLICATIONS FOR EARTHQUAKE HAZARDS

Figure 5. USGS high-resolution, seismic-reflection profiles crossing or adjacent to the Seattle fault zone. For all lines, tops of dots indicate inferred base of Quaternary deposits; tops of triangles indicate inferred base of Holocene deposits; and prominent water-bottom multiples are shown with "m’s". Solid and long-dashed bold lines show faults and inferred faults. Short-dashed lines show syncline axis at southern margin of Seattle basin. "A", "B", and "C" refer to structures in Seattle fault zone. Estimates of vertical exaggeration are based on a mean velocity in the upper 1 s of 2000 m/s.

Solid and long- dashed bold lines show faults and inferred faults. Short-dashed lines show syncline axis at southern margin of Seattle basin.
