On 19th December 2011 a blast was undertaken of 3000 cubic metres of rock above Ripaill\u00e8re (45\u00b013’41.69″N – 5\u00b043’10.93″E) a few kilometres to the north of Grenoble in France.\u00a0 The blast, which was undertaken to protect houses located at the toe of the slope, and the subsequent rockfall were captured on video and can be viewed on this site<\/a>.\u00a0 There is an image gallery of the event here<\/a>.<\/p>\n

The video is clearly a large file, so I found that allowing it completely download and then running it again was better than trying to view it as it was being streamed.<\/p>\n

There are two really interesting things here.\u00a0 First, note how a small number of boulders go a long way, even though most stop quite quickly.\u00a0 These boulders, one of which can be seen to demolish a tree, tend to be moving through a combination of bouncing whilst rotating, especially where the rotation is occurring around the shortest axis.\u00a0 Second, there is a nice example of a boulder being caught very efficiently by a rockfall fence.<\/p>\n","protected":false},"excerpt":{"rendered":"
