On November 5th 2007, there was a mudslide/flood in Mexico. A huge wall of mud and water covered a village. More than 30 people were missing and 100 houses were buried by mud and water. what happened was that part of a mountain slid into a river but the river was blocked and that caused a huge wave that covered the town of Juan Grijalva.
