Floods in France
France is currently suffering some terrible flooding that is also resulting in a serious threat of mudslides to the extent that some motorways (freeways) have had to be closed. Although not really landslides, I felt I just had to show the following pictures of the Grangent reservoir on the Loire valley, which has trapped an extraordinary amount of debris washed down the river as a result of the rainfall: Debris …

More trouble at Tangjiashan
Tangjiashan was the most serious of the “quake lakes” (valley-blocking landslides) generated by the Wenchuan earthquake. Back in June I followed the remarkable exercise undertaken by the Chinese authorities to mitigate the problem by draining the lake. Once the lake was drained the concern was what would happen in the wet season. Today, China.org.cn is reporting that new problems have developed: Two people were dead and 30 were missing amid …
