A massive landslide triggered a 2 meter plus high wave at a lake in British Columbia. The resulting wave wiped out massive full grown cedar trees all along the lake and could have an environmental impact by damming up a stream that flows from the lake and also impacting fish populations. Apparently salmon migrate through this lake also. Video coverage after the break. (Photo by CBCNews.ca)
The people living on the eastern bank of the Traunsee (map on following page) in Austria are able to observe geology in motion these days. About one million tons of soil and rock are moving in a slow landslide toward the lake, throwing over trees (picture at left) and threatening to take parts of a village with them. Moreâ€¦
[Update 12/6/07] San Diego City Council approved $20 Million for the repair of Soledad Mountain Road despite concerns by some about whether funds diverted to pay for the fix will ever be repaid by Federal and State monies. Additionally, shear pin installation mentioned on the next page is scheduled to be completed by Saturday. [/Update]
A lot has happened since my last post on the Soledad Mountain Road landslide in La Jolla. Iâ€™ll try to get you caught up on the latest with remediation and legal issues. Click through for the summary.
Residents of approximately 75 of the 111 homes evacuated after the slide have been allowed back into their homes. The City of San Diego is not wasting any time in determining the cause of the slide. The first of three 100-ft deep exploration shafts was excavated on Friday, and a Forensic Geologist from a firm hired by the City was sent down the hole to observe geology conditions and to locate the actual slip surface. Also, claims of leaking City water and/or sewer pipes prior to the failure have begun to surface. More details in the full post. (Photo by NELVIN CEPEDA / San Diego Union-Tribune)
A landslide occured about 9am PT yesterday in a residential neighborhood of La Jolla, just north of San Diego. No injuries have been reported, but estimates are that 2,500 people are without either power or gas because of toppled power lines and ruptured gas lines. The Soledad Mountain Road is currently impassable. I’ll update this post as more information becomes available. In the mean time, check out some video and a location map after the break.
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)
