High resolution bathymetric data has allowed submarine landslides triggered by the 2016 Kaikōura earthquake in New Zealand to be mapped (Gnesko et al. 2026). In total 853 slope failures were identified. I rarely feature submarine landslides in this blog – they are beyond my area of expertise – but I came across a really cool […]
