Hazard mapping in poorly known volcanic areas is complex since much evidence of volcanic and non-volcanic hazards is often hidden by vegetation and alteration. In this paper, we propose a semi-quantitative method based on hazard event tree and multi-hazard map constructions developed in the frame of the FP7 MIAVITA project. We applied this method to the Kanlaon volcano (Philippines), which is c...

Introduction: Recently released, high-resolution images from the Mars Orbiter Camera (MOC) and the Thermal Emission Imaging System (THEMIS) reveal a myriad of intriguing landforms banked along the northern edge of Terby Crater located on the northern rim of Hellas (~28°S, 287°W). Landforms within this crater include north-trending troughs and ridges, a remarkable 2.5 km–thick sequence of expose...

Geologic uncertainty in underground construction promotes design and construction conservatism and has a significant effect on project cost. Site investigation can reduce this uncertainty and decrease costs by reducing the contingency amounts included in bids. This paper presents research findings that provide a better understanding of how subsurface exploration and improved contractual risk sh...

According to the field investigation data, a meteorological forecast and alarm model of geologic disasters in Hefei Area has been established. This model was based on GIS raster data model in order to be integrated with GIS Digital Terrain Model (DTM) Component Object Model (COM). Some important factors that put premium on geological hazards, such as intraday and five-day forecasting and limina...

A new technology of classifying a seismic interval parallel to a horizon in a 3D volume based on the shape of the wiggle traces and its geologic use will be presented here. Since the seismic traces contain all relevant information, such as, reflection patterns, phase, frequency, amplitude etc., the trace shape is a fundamental property of the seismic data. A map showing the distribution of simi...

Remote sensing plays an enormous role in our understanding of the geology of solid bodies in the solar system. Inferences based on remote sensing of planetary surfaces require the use of two types of models: one for the scattering and emission of electromagnetic radiation from matter; and one which quantitatively describes the surface composition and roughness of geologic surfaces. Here, we use...

The U.S. Department of Energy (DOE) is the lead Federal agency for the development and deployment of carbon sequestration technologies. As part of its mission to facilitate technology transfer and develop guidelines from lessons learned, DOE is developing a series of best practice manuals (BPMs) for carbon capture and storage (CCS). The ―Site Screening, Site Selection, and Initial Characterizat...
