Dr. Jon Lewis, Department of Geoscience, presented the findings of his student Ellen Lamont ('11) at the American Geophysical Union's (AGU) Western Pacific Geophysics Meeting in Taipei. The work, funded by the U.S. National Science Foundation, is investigating the seismic zone activated by the 1999 Chi Chi earthquake in Tainan.
Their analyses indicate that the seismic activity in the zone is accommodating coseismic block rotations. The zone also appears to serve as a mechanical link between the core of the actively growing mountain belt in central Taiwan and the distal edge of deformation in western Taiwan.
While in Taiwan, Lewis also presented the findings of his work with student Dan O'Hara ('13) at an active tectonics research workshop held at National Cheng Kung University in Tainan. Their analysis of offshore earthquakes southeast of Taiwan suggests a mechanism for the formation of long-lived, strike-slip fault zones during the evolution of the mountain belt.
