ABSTRACT: This paper aims to
contribute to the prevention of natural disasters and generate a complement to
other similar studies. The Popocatépetl volcano has showed significant and
constant activity since 1994. The Colorada and Quimichule canyons are located
within its geologic structure; due to their topographic features, ejected
volcanic material and torrential rains in the past recent years, they put
nearby communities at risk. This work presents a geostatistical analysis to
obtain the gravity acceleration, slope by the distance-elevation relation,
height-gravity and the fluid force on the canyons. The conversion of UTM to
geographical coordinates was made with the use of the program Traninv applying
the ITRF2008 epoch 2010.0 Datum and the 14 Zone; the local gravity was
calculated with the use of International Organization of Legal Metrology (OIML)
and the statistical analysis was obtained with the use of the Geostatistical
Environmental Assessment. The structural modeling was performed usingSurfer, and the spending and
force were calculated using hydrological models. The correlation analysis
concluded that Quimichule has the greatest gravity and that it would transport
lahars faster. Mapping, geomorphological and statistical techniques and models
were applied in accordance with the study to obtain the results presented here.
