A mudslide has hit a small Mexican town called Santa Maria Tlahuitoltepec. Rescue workers are trying to find 11 missing people, including eight children.
The hillside collapsed on Tuesday morning at 4am, when most people there were in bed. At first it was thought hundreds of people had died but so far no-one's been reported dead.
The mud has buried loads of cars and homes, and cut off electricity to the town.
Some of the worst rain on record has triggered flooding and mudslides in Mexico - this nearby bridge has been snapped in half.
The town, in the southern state of Oaxaca, has been evacuated in case there are more mudslides to come.
