Research Summary:
Our planet’s vibrations give us a unique lens through which we can study various important terrestrial events, from volcanic eruptions to groundwater level to bulk characteristics of oceanwater. Seismologist Zhongwen Zhan, PhD, is pioneering the use of laser interferometry – measuring tiny shifts in light waves – to allow us to peer into the otherwise opaque interior of the planet’s rock, ice, and deep waters. By utilizing fiber optic cables, Zhan has constructed a “terrascope” which can look inwards, giving scientists critical information about increasing ocean temperatures, melting ice sheets, and tsunami-generating undersea earthquakes, enabling us to better understand and respond appropriately.
“Earth is a dynamic system — from earthquakes to erupting volcanoes, melting glaciers, and warming oceans. I listen to these changes with seismic waves to better understand our planet and prepare for what’s ahead.”
