1 March 2009
In the last year I have twice posted extensively about particular tailings dams failures and the resulting flowslides. The events in question were the 8th September 2008 Taoshi failure in Shaanxi, China and the 22nd December 2008 Tennessee Valley Authority failure in at the Kingston fossil plant in Harriman, Tennessee, USA.
The latter notes that it is not complete due to lack of data, but most of the largest events are probably recorded. It is depressing to note that the trend in occurrence through time has remained remarkably constant (see Fig. 1 below), suggesting that there is still much to do to reduce the occurrence of this type of disaster.
