Observation of Telluric Field for the Processes of Slope Breakdowns ( II )

Project Details

Description

Narrow island of Taiwan is thickly peopled and its western plain is highly developed. Along with rapidgrowing in economy, unused hillsides are nowadays successively developed. Large amount of hillsides areexploited in the recent years, which damage the original conservation of soil and water in the hillsides ofTaiwan. The rock types are sedimentary and metamorphic in the most of Taiwan mountain areas. Moreover,the mountain building in the active orogeny of Taiwan makes those areas highly fragile and unstable in thetyphoon season during May to October when 78% of rainfall averagely happened. Thus, various magnitudesof landslide events are frequently occurred during summer and autumn seasons, causing numerous disasters.An important issue is the establishment of an early warning system for landslide occurrences in the hillsidesfor protecting the safety of life and belongings to the public. Landslide can be triggered by saturated porefluid, which is absolutely one of relevant factors. Therefore, continuous real-time monitoring for thesaturation of pore fluids becomes critical in the hillsides during rainy seasons. For reducing the landslidehazards, effectively monitoring their occurrences is eager to be prospected and completed in the future. Thisstudy is planning to build up a monitoring network of self-potential and geoelectrical resistivity in a highpotential area of landslide, for example, the Taiping Mt., Ilan. The self-potential and geoelectrical resistivitymonitoring is believed to be highly associated with the pore fluid saturation underground. Combining withother physical measurements available, such as pore pressure data, it would have the greatest improvementand understanding of landslide triggering mechanism and its early warning system.
