Deep Underground Science and Engineering, EarlyView.This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Earthquake vulnerability reduction program in Colombia : a probabilistic cost-benefit analysis [PDF]
Cost-benefit analysis is a standard tool for determining the efficiency of planned projects. But one of the major difficulties in risk mitigation investments is that benefits are by nature uncertain.

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations
Deep Underground Science and Engineering, EarlyView.Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.

Vulnerability assessment using remote sensing: The earthquake prone megacity Istanbul, Turkey [PDF]
, 2007 Hazards like earthquakes are natural, disasters are not. Disasters result from the impact of a hazard on a vulnerable system or society at a specific location.

Deep Underground Science and Engineering, EarlyView.Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Investigating the status of disaster management within a world-wide context: a case study analysis [PDF]
, 2010 Disasters can be described as feats of spontaneous occurrences, in that they can happen at any minute at any time. There are two classifications of disasters, which are, natural disasters that cannot be predicted and continuously occur throughout ...
