Subsurface fluid injection can reactivate pre-existing faults and induce seismicity, posing a persistent challenge for subsurface energy operations. We couple geomechanical modelling with in-situ basin stress observations to evaluate fault-reactivation potential across a range of injection scenarios. The analysis identifies critically stressed fault orientations and proposes operational pressure thresholds that substantially reduce modelled seismic risk.

Carbonate weathering both consumes and releases carbon dioxide depending on timescale and hydrological conditions, complicating its representation in regional carbon budgets. Using paired high-frequency discharge and alkalinity measurements…

Olivine-hosted melt inclusions preserve primary magmatic signatures that are otherwise lost during bulk-rock homogenisation. We analyse a suite of inclusions from a continental volcanic arc to derive revised partition coefficients for fluid…

Probabilistic seismic hazard assessment in stable continental interiors is fundamentally constrained by short instrumental catalogues and recurrence intervals that span millennia. We develop a hierarchical Bayesian framework that jointly as…
