  El presente trabajo tiene como propósito analizar el uso y manejo de geotecnologías en la enseñanza de las geociencias en las carreras de Ciencias de la Tierra y Geografía del Instituto Pedagógico de Maturín (IPM). Se abordó como una investigación de campo, con un diseño descriptivo, utilizando una muestra de 13 docentes y 64 estudiantes de las carreras mencionadas a quienes se les aplicó un cuestionario. Como resultado se encontró que no todos los docentes utilizan estas geotecnologías en su labor académica, sin embargo, manifiestan en su totalidad, al igual que los estudiantes, estar de acuerdo con el empleo de ellas en la enseñanza de las geociencias y en el estudio del paisaje. Se concluye que el uso de las mismas es de importancia y que están dadas las condiciones para su aplicación en el aula de clase, con lo cual será posible mejorar el proceso de enseñanza aprendizaje en el ámbito de las geociencias en el Instituto Pedagógico antes señalado.   Palabras clave: Tecnología espacial; teledetección; docencia; enseñanza de la geografía; gestión ambiental.   ABSTRACT The purpose of this paper is to analyse the use and management of geotechnologies in the teaching of geosciences in the careers of Earth sciences and geography of the pedagogical institutions of Maturin (IPM). It was approached as a field investigation, with a descriptive teach, using a sample of 13 teachers and 64 students of the aforementioned careers to whom they were applied a questionnaire. As a result it was found that not all teachers use these geotechnologies in their academic work, however, Mani-Fiesta in its entirety, like the students, to agree with their employment in the teaching of geosciences and in the study of Landscape. It is concluded that the use of the same is of importance and that they are given the conditions for its application in the classroom, thus it will be possible to improve the process of teaching learning in the field of the geosciences in the Pedagogical Institute mentioned above.   Keywords: space technology; remote sensing; teaching; teaching of geography; environmental management.

Remote Sensing Interpretation

Based on remote sensing interpretation, detailed field investigation of the deposit landforms and previous research, we propose that the emplacement mechanism of the Tahman rock avalanche, a giant Holocene rock avalanche, can be divided into three distinct phases: an extension-dominated sliding phase, a lateral shear-dominated sliding phase and a compression-dominated sliding phase.

Protection Measures

A series of settlement, cracking, and collapse of the Zhengjiaping slope has been increasingly developing since October 2015 during impoundment at the Dagangshan Hydropower Station. It is a dangerous signal, which means thatlandslide potential will be existed for the Zhengjiaping slope and poses greatthreat to the operation of hydropower station and traffic safety. Related slope protection measures and research studies have been implemented accordingly in the Zhengjiaping slope to prevent and control adverse influences on property security and human life in the reservoir area. In order to understand the geological and hydrological settings of the Zhengjiaping slope and its surroundings, a field investigation was carried out to determine the lithological composition and toppling/sliding deformation characteristics using exploratory adit and site boreholes. The large deformation process in the apparently deformed area was analyzed using borehole inclinometers and global navigation satellite systems (GNSS). It was found that the apparently deformed area zone was characterized by crushed rock masses, with only a small amount of slope deposits and the sliding deformation occurring in Zone I. The deformation process of the reservoir landslide was considered to be a complex integration of the geological effects of various adverse factors. Impoundment and heavy rainfall are the direct causes of sliding deformation. During the preparation of the basic conditions for sliding, lithology, tectonic activity, and artificial disturbances play an important role, including the sliding mass and the sliding surface zone.
