Swiss officials announced over the weekend that they would halt search operations for 8 missing hikers after a massive landslide near the small village of Bondo, Switzerland. Geologists toured the source area by helicopter and determined it was unsafe to continue the search. The event is referred to as a rock avalanche by the Landslide Blog, and Professor Petley had two links to videos of the event. The first, showing the initiation of the landslide is shown below. The landslide occurred on Piz Cengalo above Bondo on August 25 and resulted in a debris flow 5 km downstream at the town.
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.
A 20 to 30-ft high retaining wall in a subdivision in San Antonio Texas failed on Sunday causing an evacuation of 80 homes. After an initial inspection, some 55 home-owners were allowed to return. The massive tension cracks that opened along the wall and behind it were 12-15-ft deep and 6-8-ft wide. Reportedly, the wall had problems even before the subdivision was even constructed. More after the break. (Photo by Jerry Lara – San Antonio Express-News)
