The bulk of the crustal shortening across the Himalayas is accommodated across the Main Frontal Thrust (MFT), forming the topographic ridges of the Siwalik Hills. Here, we quantify topographic metrics to document the geomorphic response to progressive shortening. We use the integral method of channel profile analysis to assess the topographic respo...

Development of remote sensing for geological purposes is rapidly increasing. Remote sensing provides spectral, spatial, and temporal coverage for both geologic mapping and monitoring at numerous volcanoes throughout the world. The objectives in this study were used to detect hydrothermally altered rocks, mineralized zone and surface temperature ass...

This study aimed to identify the level of tectonic activity based on morphometry analysis; ratio of valley floor width to valley height ( Vfw ), stream gradient index ( SL ), asymmetry factors ( AF ), sinuosity of mountain front ( Smf ), drainage density ( Dd). Knowing the relation between rock joint with Manggur Gadang watershed river segments, an...

The September 30, 2009, Padang earthquake has induced huge landslide in Padang Pariaman Regency, West Sumatera, Indonesia. Earthquake induce landslide occasionally occurred in tephra with a thick pumice deposit. The thickness and characteristic tephra contents of pumice, slope, presence of clay layer to the sliding surface are the main factors c...

Ensuring the safety of groundwater is essential in ensuring people's health in Gantiwarno, as most rely on groundwater. However, based on the data on disabilities in Gantiwarno, it is very probable that something hidden within its groundwater has caused a high rate of many disability forms. This study analyzes the data on the disability rate in Gan...

The occurrence of landslides in mountainous part of West Java reveals correlation to lithology and slope condition. Previous study showed that the landslides were mostly founded in the Pliocene-Pleistocene volcanic materials with the slope above 25%. This research was conducted in Mukapayung and surrounding area, Cililin District, Bandung Barat Reg...

Indonesia is placed on the subduction zone. It makes Indonesia becomes prone of earthquake activity. Earthquake can trigger another geo-hazard such as landslide. This kind of landslide was happened in Gn. Tigo, Padang Pariaman, West Sumatra in last September 2009. The aims of this study are to make sesismic slope stability models and to analyze the...
