Fears of another landslide and possible tsunami are mounting for the Anak Krakatoa volcano in the Sunda Strait, Indonesia. Scientists with Indonesia’s Meteorology, Climatology and Geophysics Agency (BMKG) have discovered new cracks that could be an early indication of another landslide. These cracks are deep and wide enough to emit steam and ash. A violent explosion of the Krakatoa volcano triggered a deadly tsunami that struck Indonesia on December 22 that struck Java and Sumatra. A landslide formed by these cracks is estimated to be 67 million cubic meters compared to the estimated 90 million cubic meters from the December 22 event.
Amazing video of a rockslide as it happened yesterday along U.S. Highway 64 in the Ocoee River gorge in Tennessee. TDOT crews had almost finished removing rockslide debris from an event earlier in the day when a second slide occurred, blocking the road again. That looks like a pretty planar joint set dipping right into the roadway and everything was wet from the recent rains. Click through for the video.
Geotechnical Engineering Challenges of British Columbia’s Sea-to-Sky Highway, gateway to the 2010 Vancouver Olympic Games
I don’t know about you, but I’ve been enjoying watching the 2010 Olympic Winter games over the past few days. If you have, you know that Whistler is the venue for many of the sports including alpine skiing, luge, skeleton, bobsled, ski jumping, biathlon and cross-country skiing among others. The Whistler area is located about 50-miles or so North of Vancouver. In order to get to Whistler, you need to drive along Highway 99, better known as the Sea-to-Sky Highway. This highway has a long history of geotechnical problems, including some significant structurally controlled rockslides and landslides. In the years leading up to these Olympic Games a fair amount of work was done on the highway with some significant geotechnical innovations.
