Susceptibility to shallow landslides of soil in the municipality of Temoaya, Mexico: multicriteria analysis

Owing to the mountainous character of the Mexican terrain, as well as the ecological effects of changes in land use, particularly in recent decades, and the occurrence of severe and frequent hydro-meteorological phenomena, the instability of slopes dislodged by precipitation constitutes a major haza...

The occurrence of SSTLs is controlled by the character of the volcaniclastic deposits, specifically pyroclastic flows of blocks, ash and pumice; because these are permeable materials they favour infiltration; if thesubjacent material is impermeable or of low permeability, water accumulates on the sub-horizontal lithological contact and transforms into a flow that leads to the instability of the overlying material.
