| Description |
English:
Two seismic-reflection scans of a fault zone in the
w:Gulf of Mexico
.
Chirp seismic-reflection show a likely w:mud volcano adjacent to the fault zone where near-surface seismic-reflection amplitudes are high and the seafloor is disrupted. Water gun data illustrate that the high-amplitude reflections extend downward in two zones, one that projects steeply (i.e., the master fault with likely gas/fluid) and another that projects laterally along apparent stratigraphy (i.e., a potential gas/fluid charged stratal unit). The fault zone has high backscatter at the sea floor, and is an area of likely upward migrating gases, fluids, and mobilized sediment, with contributions from the two subsurface high-amplitude zones. |
