Distinguished Lectureship - Speakers

Guoqing Lin is a Professor at the University of Miami. Her science portfolio encompasses themes from tectonic and subduction zone earthquakes, to volcano seismology and induced seismicity. Her research interests include high-precision earthquake relocation, seismic imaging, stress fields near faults, and structural properties at depth where earthquakes originate. She received her B.S. from Peking University, China, and Ph.D. degree from Scripps Institution of Oceanography, University of California, San Diego. Prior to her current position, she was a post-doctoral researcher at the University of Wisconsin-Madison. View Guoqing’s website.

Kīlauea volcano in Hawai‘i is one of the most active volcanoes in the world. The U.S. Geological Survey Hawaiian Volcano Observatory (HVO) operates an extensive seismic network to monitor and investigate hazards from active volcanoes and earthquakes on the Island of Hawai‘i. Seismic investigations have considerable potential for addressing key issues regarding the evolution of volcanic and tectonic activity in Hawai‘i. Specifically, what is the relationship between crustal stress changes and past and future seismic and volcanic events? To what extent are stress changes explained by known events and how predictive are they of future events? In 2018, Kīlauea experienced its largest Lower East Rift Zone eruption and caldera collapse in the past 200 years. This activity provided an unprecedented opportunity for seismologists to investigate the interactions between seismic and magmatic processes and for the general community to learn how seismologists use earthquake data to monitor volcanoes. In this talk, I will present the seismic activity in Kīlauea based on the 33 years of HVO records and focus on the changes in earthquake distribution, seismic wave speeds, and stress field before and after the 2018 eruption. I will also review the geological setting and volcanic activity of Kīlauea volcano along with other volcanoes on the Big Island.
