The eight-metre (26ft) deep trench opened up last week and severed Highway 26 between Hermosillo and the coast.
Captured by Hermosillo Desde El Cielo, the footage was shot by a drone flying along the length of the trench, which is up to five metres (16ft) across.
Farm workers and vehicles have been forced to go around the area due to the unstable ground. Another crack was reported to have opened near Highway 4 in the same area.
Geological investigations are under way into the cause of the crack, according to El Imparcial . . .
