BUSTILLOS AREQUIPA, Jorge Eduardo et al. Una breve caracterización de los fenómenos de remoción en masa (FRM): Sigchos-Ecuador. Figempa [online]. 2016, vol.1, n.1, pp.81-88. ISSN 2602-8484.  https://doi.org/10.29166/revfig.v1i1.779.

The characterization of landslides phenomena (FRM) play a very important role in the study of potential geological hazards, because it generates a very important economic and social damage. Therefore, this paper presents an analysis and landslide inventory of the canton Sigchos, scale of 1: 50000. The photogeology was a first phase of the preliminary interpretation, defining susceptible areas to FRM. In the second phase of the he analysis was performed by verification data sheets, landslides phenomena were physically characterized; in addition, the possible effects on populated areas and infrastructure of public interest was analyzed. Data processing determines that the area affected by FRM, represents 7% in the area of the canton Sigchos. The towns most affected are: Las Pampas in Isinliví with 14% of the areas; followed by Palo Quemado, Chugchilán and Sigchos. the types of FRM characterized are landslides, rockfalls and debris flows. The processes most frequently are translational and rotational slides, this type of slides represent between 99% to 82% of the identified processes. The most common materials that have been removed are susceptible to sandstones, shales, andesites and volcano sediments.
