Most people would probably not think of Norway as being hazard prone, but it does have two particular landslide issues. The first is that occasional large-scale failures occur on the walls of fjords. Given the height of these rock walls, these failures can be large and energetic, and sometimes trigger small scale tsunamis. The other is a strange type of failure known as a quick clay slide. Perhaps the best …

Given the time of year, I thought I would try to put together ten resolutions that could lead to a decrease in the impact of landslides. They are in no particular order and apply at a range of scales. I would welcome any comments. Before building infrastructure, we should always map the slopes to check for potential or actual landslides. This is not a complex or difficult thing to do, …

Back in April I posted extensively about a landslide that occurred in the town of Alesund in Norway. This slide occurred on 26th March, when a large block slipped into an apartment block, pushing it forward by up to seven metres and collapsing the lower floors. Five people were killed. This week, the outcome of the commission of inquiry has been released. The key points are as follows: Blasting of …

I spent the morning in the session on the Characterization, monitoring and early warning related to large landslides. I was struck during the presentations by the degree to which the technologies for monitoring landslides have improved over the last decade or so. For example, Casagli and his colleagues gave a very polished presentation on the application of their ground-based radar LISA to the monitoring of the Ruinon landslide near to …
