“Thunderquakes” ho! Using intense sound waves generated by thunder, scientists created maps of the shallow geology beneath a large U.S. university.
Geophysicist Tieyuan Zhu of Penn State and colleagues analyzed two and a half years of seismic signals detected by fiber-optic cables beneath its University Park campus, including more than 450 thunderquakes. The team then converted these signals into images of the near-surface geology beneath the campus — spotting regions of possible future sinkholes, among other hazards, the team reports August 21 in Science Advances .
We summarize the week’s scientific breakthroughs every Thursday.
