Tectonic, Volcanic and Fluvial Activity?

This image shows two cross-cutting depressions that may have been formed by the collapse of weak terrain along pre-existing faults. These faults are associated with the release of volcanic material and/or liquid water. Sinuous channels are visible emanating from the large vent toward the northwest. Some of these channels transition between positive-relief and negative-relief, suggesting they were once filled with erosion-resistant material.
