On September 17, CALTRANS and Kiewit Pacific held a "tunnel excavation celebration" to kick off the start of tunnel construction on The Devil’s Slide Tunnels project on California State Route 1 (the Pacific Coast Highway) in San Mateo County between the town of Montara to the south and the city of Pacifica to the north. The project involves the creation of a separated two-lane road, one lane in each direction. This road will pass through twin tunnels, over twin bridges and connect with an existing non-separated two-lane road at each end. The new road will be approximately 6,500 feet long, made up of the roughly 4,000-foot twin tunnels, the 1,500-foot north approach road (which includes the 1000-foot parallel bridges), and the 1,000-foot south approach road. Upon completion, the new road will bypass geologically unstable portions of existing Route 1, sections of roadway subject to lengthy closures, high maintenance costs over the years, and risk of permanent failure. Thanks Geology.com for the heads up. [Read on for more background, photos, maps, and movies!] (Images by CALTRANS)

A magnitude 6.8 earthquake struck Japan on 7/16/07, killing 9 and injuring more than 150. The hardest hit areas were near the town of Kashiwazaki, northwest of Tokyo. It triggered mudslides in the town that was already effected by a Typhoon several days before. One of the most newsworthy things about this earthquake is the damage to and minor leakage of radioactive waste and coolant from the world’s largest nuclear power plant in Kashiwazaki. Read on for links and video. (Photo by Kazuhiro Nogi, AFP – Getty Images)
