ABSTRACT: This paper shows the
effects caused by the combination of two factors: an anthropic factor and one
natural. The leading causes of imbalance in the subsoil due to drawdown of the
aquifer is reflected on the surface with the appearance of cracks on ground,
then came the lateral and vertical movements called faulting. This geological
phenomenon is due to a pattern of orientation is associated with a regional
fault system, lateral movement is almost imperceptible but the vertical
displacement becomes important because it is the most conspicuous and be
responsible for the damage caused to the urban infrastructure, vertical
faulting is related to the drawdown generated by intense extraction of
groundwater. The demand for groundwater, increasing year by year in the past
four decades because of the change in land use, the most significant change was
the shift from rain feed crop to irrigated crop agriculture, this change in
land use occurred on Celaya’s Valley between year period 1976-2009 was
quantified by use of remote sensing and geographic information systems (GIS).
