Brumadinho: signs of precursory deformation

A new paper (Grebby et al 2021) uses InSAR to detect precursory deformation of the Brumadinho tailings dam before the disastrous failure in 2019. The authors suggest that the failure might have been predictable with use of appropriate monitoring techniques.

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 …

Tailings dam failures: an interesting perspective article in Science

A Perspectives article in Science (Santamarina et al. 2019) argues that we need a better understanding of the processes leading to tailings dam failures as well as greatly improved management and regulation of tailings facilities

My latest paper: hillslope preconditioning

In a new paper, we examine the distribution of landslides from two earthquakes in New Zealand to see if hillslope preconditioning – the idea that the legacy of one trigger event can influence slope behaviour ins subsequent event – occurred. The results suggest that this might have been a factor in the area affected by both earthquakes,
