That bastion of “quality” journalism, the Daily Mail, has an article about the Highway 3 landslide that includes a set of high quality images of the site: tic The article correctly identifies the failure as being a dip-slope slide: “The hill had a dip slop [sic – should be slope] on the side nearest the motorway. The other side of dip slopes are steep and irregular, while the slope itself …

Thanks to reader CConkle for the heads-up on this one. An impressive slide happened this morning by the side of Freeway 10 near to Pamona in California. The slide has completely blocked the road (pictures from the LA Times): It is uite interesting that the weather does not indicate an obvious trigger for what appears to be a failure on a reprofiled slope.

Like 16,000 other Earth and environmental scientists, I am heading off next week to the Fall Meeting of the American Geophysical Union, which is held in San Francisco. I have attended several times before – it is an amazing meeting – but this year there is added spice provided by the new Natural Hazards grouping, which means that there is far more of interest for me.

Whilst pushing my five year old daughter on the swing the other day (a task that leaves plenty of time to think!), I was pondering upon the greatest landslide papers of all time. I thought that it would be interesting to compile a list and invite suggestions of alternatives. So, here is my list, in no particular order: 1.

The weather conditions were dry, the rivers are in low flow conditions, and there has not been an earthquake that could have caused the failure. So what happened? A clue may be in the landslide type. Several reports have suggested that the initial failure was a rotational slide. I am struggling slightly to get a …
