    Collection Overview: NCALM logo This collection of ALSM data near Parkfield, California was collected as an NCALM Seed grant for Michael Vadman, Virginia Tech University. This dataset provides an opportunity to create a time-series of spatially-dense displacement measurements across the creeping/transitional portion of the San Andreas fault extending from 1929 to the present. The targeted portion of the fault has experienced fairly regular M5-6 earthquakes since the ~M7.9 1857 Fort Tejon earthquake, which ruptured from Parkfield to San Bernardino.
