Origin of a crustal splay fault and its relation to the seismogenic zone and underplating at the erosional north Ecuador–south Colombia oceanic margin
Splay faults within accretionary complexes are commonly associated with the updip limit of
the seismogenic zone. Prestack depth migration of a multichannel seismic line across the …
