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.

Remote Sensing Interpretation

Xingguo County is located in the middle and low hilly mountainous areas. The area of the landslide, collapse and debris flow geological disasters is large. The sudden geological disasters such as landslides and mudslides caused by heavy rainfall are increasing year by year. This study mainly used high-altitude aerial imagery (0.5m) and Landsat 8 OLI satellite imagery covering Xingguo County as the data source, carried out remote sensing interpretation of geological environment background conditions and geological disasters in the whole area, and carried out on-site verification. At the same time, the correlation between the stratigraphic structure, topography and other factors in the study area and the spatial distribution characteristics of geological disaster points are discussed. The results show that: (1) based on remote sensing image interpretation of 377 geological disaster points; 83 landslide points, 229 hidden danger points, 17 collapse points, 26 hidden danger points, 1 hidden danger point, ground collapse point 1 At 20 places in the geological environment. (2) From the results of remote sensing interpretation, the types of geological disasters in the work area are mainly landslides and landslide hazards (including collapse type), and there are fewer collapses, collapses and debris flow hazards, and most landslide hazard points are unstable. (3) From the distribution of geological disasters, it is mainly within the scope of artificial influence. The construction of excavation slopes on the roads leads to instability of the slopes and induces disasters under the influence of rainfall. In addition, there are a large number of artificial mining mines in the work area. These places are also prone to geological disasters due to unreasonable mining and subsequent prevention and control work. (4) Areas with strong human activities, areas near the fault structure and water system roads are the main influencing factors for geological disasters in the work area.

  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.
