Geomorphological characteristics of the ruiz volcano and surroundings
(Springer International Publishing, 2015-01-01)
Landforms related to the Ruiz Volcano, the northernmost active volcano in South America, are both of volcanic and glacial origins. A brief historical account includes several eruptions and culminates with the catastrophic ...
Geomorphological mapping and landforms characterization of a high valley environment in the Chilean Andes
(2020)
Despite the wide diversity of landforms, there are only a few geomorphological maps of the Chilean Central Andes. In this study, we present a detailed geomorphological map on a 1:50.000 scale for the Diguillín Valley (Ñuble ...
Development of a Landforms Model for Puerto Rico and its Application for Land Cover Change Analysis
(Caribbean Journal of Science, Vol. 43, No. 2, 161-171, 2007, 2014)
Proglacial landform assemblage in a rapidly retreating cirque glacier due to temperature increase since 1970, Fuegian Andes, Argentina
(Elsevier Science, 2021-10)
The general trend of glacial retreat since the Little Ice Age has shown an acceleration during the last decades in Southern Argentine and Chilean Patagonia. The Fuegian Andes climatic records report an irregular mean annual ...
Mapping glacial landforms on the Chirripó massif, Costa Rica, based on Google Earth, a digital elevation model, and field observations.

Geomorphological Features of the Galeras Volcanic Complex
(SPRINGER, 2016-01-01)
The Galeras volcanic complex, near the city of Pasto, was formed in several steps. At similar to 560 ka, BP a major caldera (the Coba Negra Caldera) appeared with its center similar to 5 km west of the present-day active ...
Landform analysis of the Pueyrredón Lake area in northwestern Santa Cruz, Argentina
(Elsevier, 2013-08)
The aim of this research was to analyze the landforms around Pueyrredón Lake (NW Santa Cruz in Argentina) to contribute to the understanding of the paleoenvironmental evolution of Patagonia during the Late Pleistocene–Early ...
An inventory of cryospheric landforms in the arid diagonal of South America (high Central Andes, Atacama region, Chile)
(Pergamon-Elsevier Science Ltd, 2017-05)
An integral, glacial and periglacial, inventory of the cryosphere in the Atacama region in Chile was carried out to estimate the amount of frozen water reserves in this arid to hyper-arid region. The inventory was carried ...
Combining object-based image analysis with topographic data for landform mapping: a case study in the semi-arid Chaco ecosystem, Argentina
(MDPI, 2019-03)
This paper presents an object-based approach to mapping a set of landforms located in the fluvio-eolian plain of Rio Dulce and alluvial plain of Rio Salado (Dry Chaco, Argentina), with two Landsat 8 images collected in ...
NETVOLC: An algorithm for automatic delimitation of volcano edifice boundaries using DEMs
(Elsevier, 2013-03-22)
Accurately delimiting boundaries is required for characterizing landforms through measurement of their geomorphometric parameters. Volcanism produces a wide range of landforms, from symmetric cones to very irregular ...
