Dr. Rubin is no longer at CWU. He is currently at the
Earth Observatory of Singapore.
Summary of Recent Research Efforts:
1) Paleoseismic record of great earthquakes along the Sunda subduction megathrust northern Sumatra. Our studies will generate a record of paleo subduction zone earthquakes and tsunami along the southern part of the plate margin that ruptured in December 2004.
2) Snow avalanches. Avalanche occurrence and recurrence in time and space. Current avalanche projects include determining precursory avalanche signals (e.g., creep events) and characterizing water percolation and liquid water content of snow.
3) Magnitude 7.9, 2002 Denali earthquake, Alaska: Earthquake, recurrence, slip rates and slip-per-event along the Denali fault, Alaska
5) Why do earthquakes ruptures stop? Temporal clustering of earthquakes eastern California shear zone & variability of slip along strike-slip faults. Recurrence of earthquakes along the eastern California shear zone.
6) Recurrence of large magnitude earthquakes along reverse faults in Taiwan. A visit by earthquake geologists from the United States in collaboration with geoscientists from Taiwan began to investigate the M7.6, 1999 Chi-Chi Earthquake.
7) Variations of fault slip per event on the Carrizo Segment, San Andreas fault: Is the repetition of fault slip characteristic through time?
