Tow new videos showing rockfalls, triggered by clearance crews, in the Sumner area of New Zealand.

A video of a rockfall/slide on a road in Northern India in which a car narrowly avoids being struck by a large boulder.

Dave provides a brief review of the high levels of shaking associated with the M=6.3 earthquake in Christchurch, New Zealand yesterday, and examines the rockfalls that were the result.

GNS Science in New Zealand have been working tirelessly since the Christchurch Earthquake to assess and mitigate the hazards associated with rockfalls induced by the shaking.  They have produced an excellent five-minute video, presented by my former PhD student Chris Massey, which provides an overview of the range of rockfall types, describes the damage that they caused, and outlines the approaches that can be used to deal with them.  The …

A couple of years ago I posted a short piece on the old blog about operations in Norway to clear potential rockfalls from steep cliffs through the use of the a large (4000 kg) weight suspended beneath a helicopter.  This remains one of the most extraordinary landslide management approaches that I have seen.  Youtube now has a video, which should be visible below, that provides additional, higher quality footage of …

In the last few days a series of new videos have emerged of landslides and rockfalls as they occur.  Thanks to various people for highlighting them to me.  I am still struggling with the WordPress embed function (it was so easy in Blogger!), so apologies that some of this will have to be done through external links. First, a couple of weeks ago a debris flow killed 20 people when …

A stunning set of GNS images and information about the rockfalls and landslides caused by the February 2011 earthquake in Christchurch, New Zealand

Thanks to Greg Stock for bringing this one to my attention.  Yosemite National Park have produced a video providing information for visitors about the hazards associated with rockfalls.  It includes an extraordinary piece of footage – captured by a visitor to the park – of a rockfall detaching from the cliff, fragmenting on impact on the the slope, and then travelling down the talus slope.  The video of the detachment …

A good new rockfall video has been posted on Youtube, collected in the Pangi Valley of Himachal Pradesh in India:

Last night a fatal rockfall occurred at Stein an der Traun in Southern Bavaria. According to this report, which is also the source of the remarkable image above, the block was the “size of a house” (probably something of an over-estimate), falling from the 15 m slope behind the building. There were four people in the house at the time, of which two were killed and two were injured. There …
