Crack opens in Mexico after earthquake

Video footage has emerged of a kilometre-long crack thought to have been triggered by an underground stream in northwest Mexico.

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.
