Seeing inside the Earth with micro earthquakes  (special seminar)

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.
