Metodología y modelo para movimientos en masas (deslizamientos, derrumbes, caída, flujo y reptación) utilizando técnicas de SIG y teledetección

摘要

In the reduction of disasters caused by landslide a key step is the preparation of hazard maps, however, most effective methodologies are very expensive and require a strong technical training for implementation. As a research methodology known internationally as Mora-Vahrson with the proposed amendments, which it was considered for the application of the methodology amended as study area, the Canton Cayambe applies; in which results corroborate that the Ecuadorian territory is very prone to landslides which cause great harm to the population and natural resources were obtained.The methodology consisted in redefining the balance of constraints and triggers for landslides parameters due to the variations in relation to the place where the methodology was generated; Thus is kept fixed as the predominant factors: relief relative, lithology, soil moisture, and rainfall intensity seismicity, which represent allowed by the zoning map the instability of the land and thereby predicting the threat caused in the study area.
