Medvezhiy Glacier Advances [image] #NASA

In the early summer of 2011, the Medvezhiy Glacier in Tajikistan slid abruptly down its valley and for greater distance than it has in at least 22 years. The sudden downhill slide of the glacier raised concern among glaciologists and emergency management groups about a potential glacial outburst flood that could flow down into the Vanch River valley. According to satellite imagery and reports from local scientists, the glacier has moved roughly 800 to 1,000 meters since June 2011. The glacier normally moves 200 to 400 meters in an entire year. The mud-covered terminus of the glacier now blocks the Abdukagor River and is forming a lake behind a wall of ice 150 to 200 meters high and 300 to 350 meters across. Cracks and ice tunnels may be allowing some water to flow through; a bridge across the river downstream has been washed out from one water surge so far. The Advanced La...
