John Pomfret examines the remarkable history of the two-centuries-old relationship between the United States and China, from the Revolutionary War to the present day.
Li, "Earthquake location problems in eastern Taiwan," 1995
Cheng-Ping Li, M.S.
The SMART 2 and HTN arrays of eastern Taiwan recorded 3-component digital data in 1991. Due to the synchronization problem, the conventional location method using the first P-arrival time can not be applied. Since the S-arrival can be picked considerable accuracy using digital 3-component data, we attempt to locate earthquakes by using Ts-Tp only.
We seek the best solution in the least squares sense through a non-linear optimization process. A location program is developed and tested based on S-P intervals and 3-D ray-tracing programs. Results showed that the accuracy of relocation strongly depends on the station distribution, model definition, and the accuracy of P- and S-picking. The hypocenters were consistently shifted from east to west, implying a lower velocity underneath the island of Taiwan. The particle motion is used to discriminate the contradicting relocation results from different data sets.

The USC U.S.-China Institute presents a talk by Lenora Chu, whose new book explores what takes place behind closed classroom doors in China's education system. Chu’s eye-opening investigation challenges assumptions and considers the true value and purpose of education.
The USC U.S.-China Institute, USC Pacific Asia Museum, and USC Shoah Foundation present a screening of the film Above the Drowning Sea, the story of the dramatic escape of European Jews from Nazi-controlled Europe to Shanghai on the eve of World War Two. Followed by a panel conversation.
