Unified framework for modelling progressive to catastrophic failure in fractured media

Objective

Climate change, characterised by rising temperatures, extreme rainfall, permafrost thaw, and sea level rise, poses great new challenges for mitigating extreme geohazards like mountain collapses, glacier breakoffs, and volcanic eruptions. Many of these extreme events are due to catastrophic failure in fractured media. There is a fundamental and urgent need to reliably predict these catastrophes and minimise their consequences. Extensive evidence indicates that geomaterials commonly incubate progressive failure, characterised by diffuse, gradual, and intermittent deformations, before culminating in catastrophic failure marked by localised, rapid, and runaway rupture. As of today, it remains unresolved why, how, and when progressive to catastrophic failure occurs in fractured media, inhibiting our ability to mitigate various extreme geohazards.

FORECAST proposes that catastrophic failure may be anticipated by analysing the interplay of three fundamental variables across scales in fractured media: heterogeneity (variability of material properties), nonlinearity (intricacy in physical processes), and susceptibility (vulnerability to external perturbations). FORECAST will develop a unified modelling framework to unravel this interplay and enable physics-based, path-dependent probabilistic forecast of the timing of catastrophic events. The framework will be tested on a large database of historical and ongoing geohazard events across seemingly distinct yet mechanistically interconnected contexts of landslides, rockbursts, glaciers, and volcanoes.

Three key questions will be addressed: (i) Why does progressive to catastrophic failure universally occur? (ii) How does failure evolve under variable and uncertain conditions? (iii) When will a catastrophic failure occur? FORECAST’s outcomes will have far-reaching implications for predicting catastrophic events in not only geological and engineered materials, but also social, economic, biological, and environmental systems.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
