Corrimientos dentro del subsuelo lacustre de la cuenca de México

Abstract

Detectable horizontal differential displacements can occur in the shallow lake sediments in the basin of Mexico. The clue is generalized obstruction at the same depth (mainly between 5 to 10 m) in flexible-tube piezometers, documented at 18 different sites. Obstructions were detected by means of a cable. Field work was done a few days after the September 19, 1985 earthquake (Ms = 8.1). The generalized obstruction cannot be explained by land subsidence but could be related to the general seismic behavior of the basin.
