The Department of Geosciences and Princeton University congratulates Dr. Wenjie Lei on successfully defending his Ph.D. thesis: "Global Seismic Full-Waveform Inversion" on Wednesday, May 8, 2019.
Seismologists Jessica Irving and then-graduate student Wenbo Wu (who just defended his thesis last month!) used earthquake waves measured after a 1994 magnitude 8.2 earthquake to find underground mountains, at the bottom of the mantle’s “transition zone,” located 660 kilometers straight down.
Earth has a song, a symphony composed of ubiquitous, continuous subtle seismic signals that thrum beneath the hustle and bustle of modern society. The term “ambient seismic noise” is the “classic nomenclature found in scientific literature,” often used to describe both microseisms and seismic hum, although “these are not synonyms,” says Lucia Gualtieri, a postdoctoral research associate in geophysics at Princeton University.
In this video, The New York Academy of Sciences travel to Princeton University to meet with Blavatnik Regional Finalists in in Physical Sciences & Engineering. Lucia Gualtieri, Ph.D., a seismologist deciphering seismic background signals surrounding environmental processes such as hurricanes and landslides at Geosciences is featured along with other finalists.
