SEGURA, Gustavo; BADILLA, Elena  and  OBANDO, Luis. Landslide susceptibility in the Siquirres-Turrialba corridor. Rev. Geol. Amér. Central [online]. 2011, n.45, pp.101-121. ISSN 0256-7024.

A landslide suceptibility zonation was performed in a 10 km wide corridor along the RECOPE pipeline between the cites of Siquirres and Turrialba. The total study area is 330 km². Analysis was based on aerial photointerpretation, bibliographic research and the application of the Mora-Vahrson method (Mora et al., 1992), in which slope was used instead of the internal relief parameter. A landslide inventory map was included in the evaluation of the lithological suceptibility parameter. Zonation resulted in a predominance of areas with low landslide susceptibility (33,9%), mostly located where Tuis Formation is present, south east of the study area, followed by Suretka Formation and partially Andesitas Poás.

Keywords : susceptibility; landslides; pipeline; Siquirres; Turrialba; RECOPE; Mora-Vahrson.
