Figure 63---Seismotectonic summary of southern Puget Sound region. Red dots are relocated earthquakes at
depths from 15-30 km. Black dashed line is the outline of key block of Crescent Fm. Red arrows are maximum horizontal
stress (compression) directions from our finite-element models. Large dots are earthquakes with magnitudes >M5.8,
with year of occurrence. Several smaller dots with magnitudes of about M5.0 are also shown. Green lines are contours
of depth to the JDFP mantle.
