How to ‘see’ an underground tectonic fault

Anna will give a brief introduction to inverse problems for differential equations—specifically, how solutions to differential equations can be used to remotely probe an object. Such problems arise in areas like medical imaging, non-destructive testing, and mineral exploration.

In seismology, the Earth's interior can be investigated in various ways, such as by generating small earthquakes and analyzing the resulting seismic waves. Anna will present an alternative approach that uses GPS data from satellites to locate and monitor tectonic faults buried deep underground, even in the absence of earthquakes.
