Abstract

Between 1986 and 1990 wide cracks suddenly appeared in four different areas of the eastern margin of the Basin of Mexico. All cracks were located in the lower part of a volcanic footslope, near the edge of the former lakes of Chalco and Texcoco, in agricultural terrains with good underground drainage conditions. They appeared after heavy downpours. Some were up to 6 m deep and 1 m wide, and as long as 400 m. Their origin is related to downdraw of the water level due to pumping in wells. It is assumed that the cracks-forming process will continue.
