Rapid characterisation of landslide heterogeneity using unsupervised classification of electrical resistivity and seismic refraction surveys Open
The characterisation of the subsurface of a landslide is a critical step in developing ground models that inform planned mitigation measures, remediation works or future early-warning of instability. When a landslide failure may be imminen…

The impact of ground-ice thaw on landslide geomorphology and dynamics: two case studies in northern Iceland Open
As consequence of ongoing climate change, permafrost degradation is thought to be increasingly affecting slope stability in periglacial environments. This is of growing concern in Iceland, where in the last decade, permafrost degradation h…

Environmental baseline monitoring for shale-gas development: Insights for monitoring ground motion using InSAR analysis Open
Shale gas operations can be contentious, with a degree of uncertainty regarding the effects that they may, or may not, have on the environment. Several countries have moratoria on hydraulic fracturing until its potential effects can be und…

Debris‐flow release processes investigated through the analysis of multi‐temporal LiDAR datasets in north‐western Iceland Open
Debris flows are fast‐moving gravity flows of poorly sorted rock and soil, mixed and saturated with water. Debris‐flow initiation has been studied using empirical and experimental modelling, but the geomorphic changes, indicative of differ…
