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.

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 …
