Rupture imaging from the backprojection of body waves

A dense station deployment can be used as an antenna to track the energy radiated by the propagating rupture along the fault. This energy, coherently recorded at the stations, is back propagated to its most likely position in the source region. The result is a time-evolving image of the rupture as it starts from the epicenter and propagates on the fault.
