Inversion Exercise #3: inv3 -- large hypothetical strike-slip earthquake in Southern California
In the first stage of this problem, we distribute a dataset of teleseismic synthetics at 52 globally distributed seismic stations at which P- and SH-wave displacements are computed.

Inversion Exercise #2: inv2a / inv2b -- normal-faulting rupture on ~45deg dipping fault
In this problem, we distribute TWO sets of synthetic data, for two similar ruptures with the identical geometry.
For inv2a station distribution and velocity structure are the same as in inv1; a reduced set of stations is used in inv2b.
For inv2a synthetic data of permanent ground deformation (GPS) are provided.
