Dr. Hong Shuhui, an earthquake scientist came from National Taiwan University, visited WHIGG at the invitation of Dr. Yang Yingjie recently. Dr. Hong is an associate professor in the department of Earthquake Science in National Taiwan University. She delivered an academic report entitled Multi-scale Finite Frequency Tomography Reveals 3D Structure of the Crust and Upper Mantle Beneath Tibet's. Deputy director Xiongxiong delivered a welcoming speech. Yang Yingjie presided over the report later. More than 30 researchers and graduate students participated in the meeting.
Dr. Hong made an excellent report on how to use the limited bandwidth of multi-scale body-wave imaging technology to research Qinghai-Tibet Plateau crust and upper mantle structure. In her report, she made use of finite frequency waveform of body waves(P and PcP wave) in different frequency bands (low frequency and high frequency part). She found that the lower crust has obvious structural differences in the north-south direction of the Qinghai-Tibet Plateau. Moho surface were relatively clear from the Himalayan across yaluzangbu suture zone to the south of BanGongNujiang suture zone, and the full high-speed continuum can be seen.
Researchers and graduate students made an extensive discussion with Dr. Hong on the issues about Qinghai-Tibet Plateau underground structure, dynamic model and finite frequency.
