Last Sunday, April 25, 2010 a major landslide covered a 300-m plus stretch of Taiwan’s National Freeway No. 3, killing at least 4 people and burying three cars and destroying a bridge. The estimated volume […]
A seismologist at the University of Tokyo believes that the monstrous tsunami that was responsible for so much damage and loss of life during the 2011 Fukushima earthquake may have been a result of a […]
Since I last posted about this landslide, ADOT has added several videos to their YouTube channel. It’s clear that this highway is going to be closed for the long term. ADOT and their on-call geotechnical consultant tasked with this project, Kleinfelder, are currently drilling boreholes to attempt to characterize the failure surface and determine what the geometry of the failure surface is. They are installing at least 10 inclinometers to try to determine the location of the slip plane or planes at depth and they have two extensometers to measure if any additional movement occurs. They are also performing LIDAR surveys as well. Check out the videos below.
