When the earth moves, Prof. Katie Keranen, earth and atmospheric systems, watches.
Keranen images the Earth’s crust by studying the propagation of energy waves through rock, a field known as seismology. The sources of these waves are subdivided into two categories: natural or passive sources, such as movement caused by earthquakes, and active sources, which are manmade.
