Zonas urbanas marginadas vulnerables a procesos de remoción en masa, zona norte, delegación Álvaro Obregón, Ciudad de México, 2015-2018

Abstract

The reason for carrying out the following research work is the lack of information, attention, management, coordination, on the part of the Delegational, State or Fed-
eral authorities, on the presence of irregular human settlements in urban areas in the vicinity of the northern zone. The Álvaro Obregón delegation, in which there is
some degree of physical vulnerability and high level of marginalization on the part of the families, who inhabit these areas, located on slopes, river channels and / or
ravines, derived from the geomorphology of the place; they are a constant danger due to their pronounced degree of inclination and when this landslide or mass re-
moval process takes place, it drags or carries the foundations of the buildings and what is in their way, especially in the rainy season and / or in earthquakes , which
causes human, environmental and economic losses.
On the other hand, this results in an environmental deterioration around the ecosystem that was originally and that was arbitrarily modified over the years with
this disjointed urbanization (see Map 5), since when these types of constructions and buildings are made in areas not suitable for habitability because of the problems
mentioned above, eliminates or replaces the vegetation cover, being modified by the foundation grade, observing the non-filtration of rainwater by the compaction of
the soil in terms of the use of materials for construction.
Something of utmost importance, is that the people who live in these areas with some degree of vulnerability, fill or fill in some way small cavities or mines with
gravel material, solid waste or garbage for leveling the soil, which only increases and brings serious consequences, making it even more unstable.
