Features hiking, skiing, paddling, biking, and more New and substantially revised trips with all new full-color photos and maps throughout Emphasis on traverses and loop trips for both summer and winter, always with simpler and shorter options Originally published in 1972, the classic guide known as 55 Ways to the Wilderness in Southcentral Alaska has been fully updated and reinvented as Alaska Adventure 55 Ways. This robust reboot covers a diverse range of activities for year-round fun, from quick day trips to adventures that could extend to a week or longer, including canoe trails, wilderness cabins, easy summits, forest walks, cross-country ski routes, summer mountain biking and winter fat bike trails, wild skating, and more. John Wolfe Jr. and Rebecca Wolfe, a father-daughter team, describe activities spanning the broad swath of Southcentral Alaska, 300 miles north to south and 350 miles east to west. The guide features activities on the lakes and peaks of the Kenai Peninsula, the Anchorage front range, the Matanuska and Susitna Valleys, and the Copper River basin, taking in Chugach and Denali State Parks, Chugach National Forest, Kenai Fjords and Wrangell St. Elias National Parks, several wildlife refuges, and portions of the Iditarod National Historic Trail. With an emphasis on adventures regular people can enjoy and destinations that don’t require highly technical skills, expensive flights to remote locations, or demanding levels of athletic fitness, this guide appeals to all ages, with family-friendly shorter options and trip extensions adding up to more than a hundred "ways" to adventure.

Natural Hazards focuses on hazards as the interface between humanity and its needs for space and resources, as well as on the ongoing geologic processes of Earth and features many new Canadian examples and discussions while retaining the best U.S. and international illustrations. The third Canadian edition strikes an ideal balance between the scientific and the human aspects of natural hazards, combining basic scientific principles within a solid social framework.

Comprises a selection of articles on interactions between earthquakes and the soil in which they propagate. The book is concerned with soil composition and geomechanical features, which affect earthquake propagation and intensity; it also addresses detrimental effects of seismic shaking on soil properties and stability. Modelling is applied to investigate the effects of cracks and various types of soil damping on seismic waves. Elastic, poroelastic, elasto-plastic, constitutive models are adopted in conjunction with rigorous mathematical techniques or approximate methods such as boundary elements or finite differences. A substantial part of this volume is dedicated to soil liquefaction, an important consequent of seismic shaking that results in substantial loss of soil strength and stiffness. Criteria are proposed for assessing the liquefaction potential of a site. Data collected from soil samples, either in the laboratory or in-situ, are analysed to provide values for the critical parameters on which liquefaction depends. The occurrence of landslides is addressed by assessing slope stability through a systematic geophysical and geotechnical characterisation of the soil mass followed by finite element modelling. The bearing capacity of the soil is directly obtained by laboratory testing of soil samples, as well as from reliable empirical relations generated by combining such test data with in-situ measurements of soil dynamic properties.

A description and analysis of the damage resulting from submarine landsliding, seismic sea waves, and oil-tank fires in one of the most devastated cities in Alaska.

Natural Hazards: Earth Processes as Hazards, Disasters and Catastrophes, Fourth Edition, is an introductory-level survey intended for university and college courses that are concerned with earth processes that have direct, and often sudden and violent, impacts on human society. The text integrates principles of geology, hydrology, meteorology, climatology, oceanography, soil science, ecology and solar system astronomy. The book is designed for a course in natural hazards for non-science majors, and a primary goal of the text is to assist instructors in guiding students who may have little background in science to understand physical earth processes as natural hazards and their consequences to society. Natural Hazards uses historical to recent examples of hazards and disasters to explore how and why they happen and what we can do to limit their effects. The text's up-to-date coverage of recent disasters brings a fresh perspective to the material. The Fourth Edition continues our new active learning approach that includes reinforcement of learning objective with a fully updated visual program and pedagogical tools that highlight fundamental concepts of the text. This program will provide an interactive and engaging learning experience for your students. Here's how: Provide a balanced approach to the study of natural hazards: Focus on the basic earth science of hazards as well as roles of human processes and effects on our planet in a broader, more balanced approach to the study of natural hazards. Enhance understanding and comprehension of natural hazards: Newly revised stories and case studies give students a behind the scenes glimpse into how hazards are evaluated from a scientific and human perspective; the stories of real people who survive natural hazards, and the lives and research of professionals who have contributed significantly to the research of hazardous events. Strong pedagogical tools reinforce the text's core features: Chapter structure and design organizes the material into three major sections to help students learn, digest, and review learning objectives.
