In the 1970s, a significant number of structural and geological investigations were carried out in Cuba, all complemented by geophysical data and perforations, Allowing the first division in morphostructural blocks of different hierarchical orders: megabloque, macroblock, mesobloque and smaller blocks. The southern plain of Pinar del Río is located in the mesobloque Batabanó, bordered by the mesobloques Pinar and Habana-Matanzas, and controlled by the Southern Cuban fault system. In the southern plain of Pinar del Río, recent vertical velocities of the order of +2.0 to +4.0 mm / year are reported, according to the geodetic investigations of successive leveling made by others authors in 1989, which influence the conformation of the current relief. The existence of different local morphostructures, anomalies in the drainage network and a coast with submersion characteristics, which condition its marshy nature, are elements that point to the existence of these movements. In general, the main methods used to recognize neotectonic deformations have been instrumental (seismological and geodetic), historical-archeological and geological-geomorphological investigations. In Cuba, sedimentary-structural criteria have been applied to differentiate the tectonic styles of the pliocene-quaternary deposits with respect to the folded substrate. Simultaneously, these hypotheses were corroborated by geophysical criteria and deep drilling data. The development of digital elevation models allows the quantitative characterization of the relief and to recognize the tectonic effect in its evolution, especially in very active tectonic zones. As an essential support for the neotectonic investigations of the Cuban archipelago, quantitative geomorphological investigations and teledección techniques were also included. In these works, morphothectonic methods were applied in a very limited way, since there were no numerical models of the terrain that facilitated their use. In the case of Cuba, the criteria for placing the neotectonics stage in geologic time vary greatly. While some authors identify its inception at the end of the Paleogene, others place it between the late Eocene and the Miocene. From the geomorphological perspective, the neotectonics stage is divided into two sub-stages: early neotectonics (Oligocene-Miocene) and late neotectonics (late Miocene to Pleistocene). In relatively flat regions, such as the southern plains of the Pinar del Río Province, in western Cuba, evidence of neotectonic deformation is not always easily identifiable, especially when attributed to recent geological history. A compounded approach is therefore necessary. During the last prospecting works for sand and gravel deposits, certain regularities were established in the distribution of alluvial sediments, the former riverbeds and the diversion o","PeriodicalId":39866,"journal":{"name":"Investigaciones Geograficas","volume":"2017 94","pages":"Pages 3-19"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.14350/rig.56388","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91985377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this article aims to provide detailed information on analytical geomorphological methods and interpretations of morphography and energy for Mexico’s relief, considering two calculations according to unit area: density contour (km/km<sup>2</sup>) and maximum difference of heights (m/km<sup>2</sup>) - both relief índices -, with the support of GIS ArcView, ArcGIS, and ArcInfo software. A review of existing national atlases revealed that not all countries have morphometric data on their reliefs. Indeed, mapping of this type was only found, in chronological order, in the National Atlas of Cuba (1970), the Atlas of the Slovak Socialist Republic (Slovak Cartography (1983), the National Atlas of Hungary (Geographic Research Institute of the Hungarian Academy of Sciences (1989), the New National Atlas of Cuba (1989), and the National Atlas of Mexico (1990), all on a small scale. In other national atlases, there are only hypsometric and slope steepness maps. The stages for mapping the geomorphometric units of Mexico’s relief were: (1) Construction of the morphographic map: a) Calculation of density contours, b) Data analysis and reclassification, c) Spatial generalization by minimum mappable area, and d) Smoothing of geographic limits; (2) Obtaining a relief ’s energy map: a) Construction of the Digital Elevation Model (DEM), b) Calculations for the relief ’s energy map, c) Data reclassification, and d) Spatial generalization; (3) Production of a map of the relief ’s geomorphometric units: a) Overlaying of the morphographic and relief ’s energy maps, b) Spatial statistics, and c) Map of geomorphometric relief units: and 4) Definition, according to morphographic contour, of the two predominant classes of the relief ’s energy. The morphographic map (density of contours in km/km<sup>2</sup>) shows nine range classes: less than 1.0, from 1.0 to 2.0, from 2.1 to 3, from 3.1 to 4, from 4.1 to 5, from 5.1 to 6, from 6.1 to 7, from 7.1 to 8.0, and more than 8.0. On the other hand, the map of the relief ’s energy has 9 ranges (m/km<sup>2</sup>): less than 10.0, from 10.1 to 20.0, from 20.1 to 50.0, from 50.1 to 100.0, from 100.1 to 200.0, from 200.1 to 300.0, from 300.1 to 400.0, from 400.1 to 500.0, and over 500.0. An analysis of this country’s territory reveals that very highly dissected mountainous relief, with dissection values ranging from 501 to 1 300 m/km<sup>2</sup>, evidences a monolithic location pattern associated with major breakups due to erosion in the central portion of the Sierra Madre Occidental and, i","PeriodicalId":39866,"journal":{"name":"Investigaciones Geograficas","volume":"2017 94","pages":"Pages 49-63"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.14350/rig.57019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131653861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Costa Rica, for example, these phenomena cause approximately 30% of the disasters that affect the country each year. The study area comprises a section of 52 km<sup>2</sup> in the extreme geographical coordinates: 10,23 ° N and 10,18 ° S; -84.23 ° W and -84.14 ° E; which is located on the northeast slope of the Poás volcano in Costa Rica and has the physical characteristics of rainfall above 2000 mm per year, intense tectonic dynamics associated with different tectonic faults and dense tropical vegetation. The objective of this work is to show a morphometric model to determine susceptible areas to hillslope processes, starting from the case study of the most affected region by the landslides triggered during the Cinchona Earthquake in 2009. The morphometry or geomorphometry is the quantitative analysis of the terrestrial surface; among its fundamental variables are altimetry or hypsometry, slope of the terrain and drainage density. The morphometric methods used are based on the approaches of Simonov (1985), Lugo (1988) and Zamorano (1990). Seven morphometric maps were developed that indirectly explain the geomorphological dynamics of this territory. Firstly, the cartography of dissection density, depth of dissection, relief energy and total erosion were performed. The density of the dissection calculates the concentration of river channels in a specific area, aiming to establish zones of greater or lesser concentration of river courses and therefore with greater river erosion. The depth of the dissection aims to measure the erosive capacity or activity of rivers vertically, as it analyzes the areas where river erosion has been more (or less) intense over time and provides an indirect relationship of the parameters that allow the dissection to increase, such as lithology, terrain inclination, precipitation and substrate weakness planes. The relief energy determines the maximum difference of the relative height in meters in a specific area and represents the potential energy that emerges from the relief. The total erosion determines zones with greater or less erosion of the recorded relief by means of the density of the curves of level in a determined area (by minimum spatial unit of analysis). All these parameters were analyzed from the three morphological regions that make up the study area (Poás volcanic complex, pyroclastic ramps and valley slopes), and then integrate these variables into the slope susceptibility map. Subsequently, the results of the map of susceptibility to hillside processes were compared with the coseismic mass movements of 2009, which resulted in that 98% of these phenomena coincided with the areas of frequent occurrence and maximum occurrence.
