Book excerpt: From out of the clear blue sky, an unknown chunk of rock from the frozen void strikes the Earth with unimaginable force, gouging a wound into the very crust of the planet. Millions die in an instant, and millions more await the end as the looming catastrophe unfolds...Thousands of miles away from the disaster, a call comes in the middle of the night. Families act, and react, and while panic spreads, the world keeps on spinning. Maybe a little slower, and perhaps with a teeny bit more of a tilt, but such things are a mere trifle to the existence of a planet. For the human inhabitants of this planet, though, the meteor's collision will have far-reaching effects as the impact creates ripples throughout their fragile existence.Bryan Hardin just wanted to create a sanctuary in the country for his remaining family, a place to heal his wounded spirit as he struggles with survivor's guilt and approaching middle age. He's hardly the heroic type, but his family is going to need all of them to act like heroes if they are going to survive the spreading effects of the Rockfall. The Earthquakes are Primary Effects.The Tsunami are Secondary Effects.Will Anybody Survive the Tertiary Effects?

This book was released on 2014-03-26 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the afternoon of December 12, 2013, a large, joint-controlled block of the Shinarump Conglomerate Member of the Chinle Formation, with an estimated volume of almost 1400 cubic yards and weighing about 2700 tons, detached from the cliff face at the top of the Rockville Bench in Rockville, Utah. The block fell on to the steep Moenkopi Formation slope below the cliff, and shattered into numerous cobble- to very large boulder-sized fragments. The fragments moved rapidly downslope before striking and destroying a house, detached garage, and car at 368 West Main Street in Rockville. The two occupants in the house were killed. The purpose of this 20-page investigation wast to document the characteristics of the fatal rock fall; evaluate future rock-fall hazard at and near the site; and provide recommendations for homeowners, the Town of Rockville, and other officials to consider in managing rock-fall risk. Although the first fatal event, this rock fall is the sixth large rock fall within the Town of Rockville in the 35 years prior to December 12, 2013. Five of those events occurred within the past nine years, and at least three of those struck and damaged structures at the base of the Rockville Bench.

This book was released on 2015-11-06 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This pioneering work deals with the parameterization of rockfalls in the context of 3D run-out modelling at a study site in the Bavarian Alps. The main objective was to cover not only low-magnitude, high-frequency rockfalls (10 msup3/sup) but also Mid-Magnitude events, which involve rock volumes of between 10 and 100 msup3/sup (boulder falls) and between 100 and 10,000 msup3/sup (block falls). As Mid-Magnitude events have been insufficiently covered in terms of rockfall modelling up to now, a geomechanical approach has been developed to characterize those events by means of a case study. For a 200 msup3/sup limestone block a potential failure scenario was analysed by combining a deterministic failure analysis with a numerical process-based run-out model. To model potential run-out scenarios of the 200 msup3/sup block, the beta version of the code RAMMS::Rockfall, developed by the Swiss Institute for Snow and Avalanche Research (SLF), was applied. RAMMS::Rockfall makes it possible to include the block shape and thus consider the effects of varying block shapes on the run-out distance. The run-out modelling for the entire project site was performed using the scientific code Rockyfor3D (Dorren/ecorisQ). To provide quantitative information in terms of input parameters, a field recording of block sizes at the talus slope, as well as a detailed discontinuity analysis at the source area, were conducted. The book successfully demonstrates how detailed and quantitative field investigation can contribute to 3D rockfall modelling./pp

Book excerpt: Mass movement of rocks in high mountains can severely injure the population and damage man-made structures in these areas. This book focuses on the understanding of the mechanisms of rockslides and rockfalls using a quantitative approach. The range and velocity of these hazards are calculated to serve as a basis for evacuations and other preventive measures. Examples from four continents illustrate the necessity of this kind of information. The book contains a wealth of information for practitioners and scientists working in the field of catastrophe prevention.

Available in PDF, EPUB and Kindle. Book excerpt: Progressive failure has been a classical problem in the field of geotechnical engineering and has attracted considerable attention in connection with slope stability and foundation problems. It is associated with strain localization or shear banding and is also related to damage in material structures. As knowledge of the progressive failure mechanism increases, it is now necessary to establish effective communications between researchers and engineers. The International Symposium on Deformation and Progressive Failure in Geomechanics provided an opportunity for discussing recent advances in this area. A total of 136 papers were contributed from 22 countries. As well as these, the symposium proceedings also contain 8 interim technical reports on the subject by the members of the Asian Technical Committee of the International Society for Soil Mechanics and Foundation Engineering and the Japanese Geotechnical Society National Committee on Progressive Failure in Geo-structures.

Book excerpt: This research project is directed at developing and demonstrating a system for cost effectively evaluating and prioritizing highway rockfall hazards statewide. This pilot study produced a prototype computer-based highway rockfall hazard ranking system - "CRASH", which can be used to identify those areas of the state's highway system which have the highest incidences of rockfall accidents, as well as any area which has had a reported rockfall accident since 1976. The existing Oregon rockfall hazard ranking system (ODOT system) was selected and studied to determine if it addressed the varied geologic as well as physical rockfall situations in Colorado. This system was adapted to suit the requirements of our prototype hazard ranking scheme. Implementation of the Highway Rockfall Hazard Evaluation system was demonstrated on five pre-selected areas. The mile in each area with the highest number of reported rockfall accidents, as determined by "CRASH", was ranked using the ODOT system
Download or read book Colorado Rockfall Simulation Program written by Timothy J. Pfeiffer and published by . This book was released on 1993 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This rockfall computer program, which simulates rocks tumbling down a slope, predicts the statistical distribution of speed and bounce height, and can be used for locating and designing rockfall mitigation. The model takes into account, slope profile, rebound and friction characteristics of the slope, and spinning energy of the rocks. Spherical, cylindrical and disk shaped rocks can be simulated. At each impact, the slope angle is randomly varied from the nominal value input by the user within the limit set by the maximum probable variation in the slope. Version 3.0 of the Colorado Rockfall Simulation Program is similar to version 2.1 in terms of the operating environment, but additional statistical output has been added and the ability to use metric units has also been added. This manual reflects version 3.0 input and output. The model is recommended as a tool for geologist[s] and engineers responsible for analyzing and mitigating rockfall hazards."--Technical report documentation page.

Download or read book Modeling Gravity Hazards from Rockfalls to Landslides written by Vincent Richefeu and published by Elsevier. This book was released on 2016-10-11 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gravity hazards are a major concern to those living in mountainous areas. To protect infrastructure and human life in these areas, engineers require numerical tools for trajectory analysis, for application from fragmental rockfalls to large-scale avalanches or landslides. This book explores state-of-the-art methods to model the propagation (flows and stops) of masses, using the discrete element method (DEM) to study the evolution of kinetics during an event. Taking into account the shape of the blocks and the topology of the terrain provides an explicit and sophisticated consideration of geometries, eliminating the need for stochastic inputs to rockfall simulations. This method is validated experimentally, before the authors apply it to real case studies. The book ends with an introduction to and comparison with the material point method (MPM), a new and promising approach able to bridge the gap between cases dominated by discreteness and those involving a very large number of elements. Engineering consulting firms, researchers and students should find the approaches outlined in this book useful, whether designing prevention and protection systems for gravity hazards, or exploring new ways to model gravity hazards. Covers conventional methods used to study gravitational phenomena using empirical parameters Presents a new numerical tool taking account of the physical phenomenon (friction, dissipation, realistic block shapes) and a methodology for parameter calibration and the achievement of numerical simulations Applies the numerical model to real cases with a critical analysis of its applicability in the field of engineering Emphasizes the discrete element method (DEM)
