Pre-failure analysis of the Fagraskogarfjall landslide
NPA Satellite Mapping have completed a pre-failure analysis of the Fagraskogarfjall landslide in Iceland using InSAR data. Up to 2 metres of movement occurred in the year before the main collapse.

Rattlesnake Hills rockslide – anticipating future behaviour
The Rattlesnake Hills rockslide in Washington State continues to creep at an approximately constant rate. The key challenge now is to determine whether the slide can transition into a rapid failure eventThe Rattlesnake Hills rockslide in Washington State continues to creep at an approximately constant rate.

Highway 97 update
Blast on the problem slope on Highway 97 (from CBCnews) Attempts to deal with the slope problem on Highway 97 in Canada continue in a quietly controlled manner, and there are now some signs of success. The focus continues to be upon small blasts at the head of the slope to remove material, which is then transferred to the toe to support the mass and to protect the highway. The …

Did you hear the one about a goat in a landslide?
A bit of light relief over at the Highway 97 site in Canada, which continues to slip. Arthon have a pictorial report on their website of the rescue of a mountain goat that had fallen down the tension crack and become wedged 10 m below the surface (all images from the Arthon website): Fortunately, the goat (now named Houdini) was spotted and a rescue was put in place. Enter the …
