Abstract: Methods, computing systems, and computer-readable media for processing seismic data. The method may include obtaining a model of a subterranean domain, and determining one or more synthetic waveforms for one or more events located in the subterranean domain, based at least partially on the model. The method may also include identifying, using a processor, one or more arrival waves in the one or more synthetic waveforms, wherein at least one of the one or more arrivals represents a mode-converted wave, and generating a processing chain for determining at least a location of an event in the subterranean domain based at least partially on the at least one mode-converted wave.
