When a seismic wave passes between two porous layers beneath the earth, some of its kinetic energy gets converted to electromagnetic energy. That's interesting to geophysicists because if hey can understand the relationship between the two types of waves, the EM waves could provide valuable information about what is going on in the subsurface. This video by Dr. Niels Grobbe, a former ERL postdoc who is now an Assistant Researcher at the University of Hawaii at Manoa, demonstrates a mathematical model of that relationship. This work was a collaboration with several researchers here at ERL / MIT Department of Earth, Atmospheric and Planetary Sciences and at TU Delft, and this is one of several new videos created by our researchers for the Society of Exploration Geophysicists meeting.
