Characterization of Susceptible Landslide Zones by an Accumulated Index
In order to characterize the landslide susceptibility in the central zone of Guerrero State in Mexico, a spatial model has been designed and implemented, which automatically generates cartography. Conditioning factors as geomorphological, geological, and anthropic variables were considered, and as a detonating factor, the effect of the accumulated rain. The use of an inventory map of landslides that occurred in the past (IL) was also necessary, which was produced by an unsupervised detection method. Before the design of the model, an analysis of the contribution of each factor, related to the landslide inventory map, was performed by the Jackknife test. The designed model consists of a susceptibility index (SI) calculated pixel by pixel by the accumulation of the individual contribution of each factor, and the final index allows the susceptibility cartography to slide in the study area. The evaluation of the obtained map was performed by applying an analysis of the frequency ratio (FR) graphic, and an analysis of the receiver operating characteristic (ROC) curve was developed. Studies like this can help different safeguarding institutions, locating the areas where there is a greater vulnerability according to the considered factors, and integrating disaster attention management or prevention plans.

Proposal of Rural Housing and Habitat Improvement of the Town El Encanto, in Tapachula, Chiapas, Mexico
In the state of Chiapas, Mexico, there are numerous rural communities located in isolated territories and away from important population centers. Families, in essence, have indigenous roots and low economic incomes and, because of this condition, their homes are precarious, unsafe and unhealthy, with many limitations to access basic water and sanitation services, as well as basic health services, recreation, education, communication, etc. This study analyzed the housing and habitat problem of the El Encanto community, located on the coast of Tapachula, Chiapas. As a result, structurally safe, economical and healthy housing proposals were developed, with water and sanitation services, functional spaces with sociocultural characteristics, typology and appropriate to environmental conditions, with the use of ecotechnologies and building materials of the place for the conservation of the environment and biodiversity, in addition, proposals for community equipment for habitat improvement were developed.
