Abstract:
Earthquakes produce seismic waves. They provide a way to obtain
information about the deep structures of our planet. The typical
measurement is to record the travel time difference of the seismic
waves produced by an earthquake. If the network of seismometers is
dense enough and they measure a large number of earthquakes, we can
hope to recover the wave speed of the seismic wave from the travel
time differences. In this talk we will consider geometric inverse
problems related to different data sets produced by seismic waves. We
will state uniqueness results for these problems and consider the
mathematical tools needed for the proofs. The talk is based on joint
works with: Maarten de Hoop, Joonas Ilmavirta, Matti Lassas and
Hanming Zhou.
