+Event Based Liquefaction Demo
+
+This calculation demo exercises the Event-Based liquefaction calculator with a
+trivial source model logic tree, containing a single model with two area source.
+This source adds complexity to the calculation due to uncertainties present in
+nodal plane distribution and hypocentral depth.
+
+We compute a Ground Motion Field, Liquefaction Occurence, and Probability of
+Liquefaction for each rupture.
+
+Expected runtime: ~1 minute
+Number of sites: 4154
+Number of logic tree realizations: 50
+GMPEs: AbrahamsonEtAL2014 (0.5), CauzziEtAl2014 (0.5)
+IMTs: PGV
+Outputs: Stochastic Event Sets, Ground Motion Fields
