Usually, the definition of geotechnically homogeneous zones is established through the analysis of information on a regional (and even national) scale of those characteristics that define the topographic, geological, climatic, and land use conditions by categorizing them and applying algorithms of interaction between these variables. However, in technical literature and in technical reports of state entities that manage natural hazards, new advances are being made in the determination of other aspects or variables that detail the condition of geotechnical susceptibility; at the same time, nowadays there are technological tools for the massive analysis of information and its spatialization. This article presents a new approach to the definition of geotechnically homogeneous zones using these technological tools. A comparison is made against the conventional definition.
About 20% of Cenit’s hydrocarbon transport infrastructure are located on mountainous terrain susceptible to effect of geohazards. There is an integrity management plan based on inspection, monitoring and mitigation activities; however, the occurrence of accidents triggered by geohazards has caused emergencies with effects on environment receiver and on operation of transport systems This paper presents, through management some of these accidents, good practices identified, learning in terms of prevention, preparation and response to emergencies and identification of priorities and gaps, in order to strengthen continuous improvement of the geohazards integrity management strategy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
