The role of earthquake and rainstorm induced landslides in shaping mountain chains
A new study published in Science Advances (Wang et al. 2020) shows that rainstorms tend to trigger landslides that sculpt the landscape at lower levels, whilst earthquake induced landslides cause erosion at higher elevations.

Spatial and temporal patterns of landslide losses in Colombia
Spatial and temporal patterns of landslide losses in Colombia Back in 2012 I posted about the levels of landslide losses in Colombia, which is one of the most landslide prone countries, based on my fatal landslide database. I noted that levels of loss are high, especially in the western side of the country, and that Colombia needs to be a priority country if we are to reduce loss worldwide. It …

The exceptional mobility of tailings dam failures
The exceptional mobility of tailings dam failures I’m continuing to write my paper for the keynote at the 13th International Symposium on Landslides in Colombia this year (the paper is due this month, so the pressure is on). As I noted in a post last week, I’ve been looking at the impact of landslides in less developed countries; one key component of this is the impact of failures associated with …
