Summary:
Scientists have been studying the impact of clear-cut logging on avalanche terrain in British Columbia. Understanding avalanche behavior and its destructive potential is an important factor in assessing risk of clear-cut logging of mature forest timber. A new article presents data collected from locations where avalanches have been released due to clear-cut logging; These data demonstrate the adverse effects of poor logging practices.

Scientists with the UBC Avalanche Research Group have been studying the impact of clear-cut logging on avalanche terrain in British Columbia. Understanding avalanche behavior and its destructive potential is an important factor in assessing risk of clear-cut logging of mature forest timber. An article just published in the Canadian Geotechnical Journal presents data collected from locations where avalanches have been released due to clear-cut logging; these data demonstrate the adverse effects of poor logging practices.

"The idea of this study was to be able to predict, in a probabilistic sense, how far avalanches can penetrate into forest cover. It is important not only in logging applications but also for land-use planning in general," says author Dr. Dave McClung of the UBC Avalanche Research Group. "The runout distance of an avalanche that penetrates forest cover can only be predicted using the methods in this paper. Avalanche dynamic models cannot be used for such an application since they cannot account for the extra resistance of forest cover. If facilities -- buildings, roads, etc. -- are below avalanche terrain, planners need to know the chances that destructive avalanches can reach such facilities. This article contains the methods and data for doing so."

Dr. Ian Moore, Editor of the Canadian Geotechnical Journal, commented "We greatly value research publications in the Journal having a practical focus. This study from Dr. McClung and his colleagues is a wonderful example of work of high scholarly value having very significant safety implications. The result will be management of resources to improve both commercial and safety outcomes associated with optimized forestry practices."

Nasa Gives You An Excuse to Post a Selfie on Earth Day

TheStreet (Apr. 22, 2014) — NASA is inviting all social media users to take a selfie of themselves alongside nature and to post it to Twitter, Facebook, Flickr, Instagram, or Google Plus with the hashtag #globalselfie. NASA's goal is to crowd-source a collection of snapshots of the earth, ground-up, that will be used to create one "unique mosaic of the Blue Marble." This image will be available to all in May. Since this is probably one of the few times posting a selfie to Twitter won't be embarrassing, we suggest you give it a go for a good cause. Video provided by TheStreet
