A review of a new paper that has identified a new, large, ancient landslide in northern California. The landslide dam had a surprising impact on the local fish population

The remarkable slope failures in the sediments at Lake Condit in Washington State USA, which were caught on video, illustrate the processes associated with slope failure during rapid draw-down.

The first set of images of landslides triggered by the recent Christchurch earthquakes in New Zealand. This set show a house that has been struck by a large boulder.

News today, barely covered in the international mainstream media so far, of a new tailings-related landslide in Hungary yesterday.  The only English report that I have seen so far is on the Chinese CriEnglish website, which reports that 700,000 cubic metres of bauxite ore formed a flow that struck three villages in Veszprem county.  These villages appear to be Devecser, Somlóvásárhely and Kolontar.  The Google Earth imagery of this area shows the origin if the accident …

Thanks to Ivan Montanari for pointing this one out to me.  There was a big new rockfall at the Attabad landslide site today, caught on camera and posted on Youtube.  You should be able to view it below: The implications of this include:1. There is a chance that a failure like this could block the spillway;2. There is a chance that a landslide could send a wave over the top …

Probe International image of a landslide The Three Gorges Dam in China is one of mankind’s greatest achievements or a folly on a grand scale, depending upon your point of view. Whichever is correct, there is little doubt that its construction is an extraordinary engineering achievement. The final aim of the project was due to be achieved this month as the lake is finally elevated to its maximum level. However, …

One of the great concerns about the Three Gorges Dam in China has always been the potential for large-scale landslides. As the project nears completion, inevitably very over-budget, the level of the lake is rising and the cost of these landslides in becoming apparent. Today AFP and Xinhua have runs stories that raise concerns still further. These stories report that since September there have been 166 landslide and debris flow …

This is the fourth part of my photographic description of damage caused by the Sichuan earthquake. The other parts are as follows: Part 1: Beichuan townPart 2: The Tangjiashan landslidePart 3: Hanwang townPart 4 (this part): The Mianyuanhe areaPart 5: The Xingyiu area First a location map. The Mianyuanhe area is a fairly large river valley that cuts through the Longmen mountain chain, with its mouth as Hanwang as shown …

Many thanks to reader Ripendra for alerting me to the following, and indeed for doing nearly all the work for this post. The 14th June 2008 earthquake in Japan is known to have triggered a number of landslides, as per earlier posts, but the most notable appears to have occurred at Aratozawa Dam in Miyagi prefecture. The Aratozawa Dam (Figure 1) is a rockfill dam used for flood control, irrigation …
