2. Task 3.3 European crustal strain-rates Deliverables: D3.5. Reference strain rate models for the Euro-Mediterranean region (INGV, Month 24) Comments: - Results from national efforts already available - A robust alternative to observed slip rates (almost non-existent throughout most of central and northern Europe) Problems: - Will not be able to resolve the entire study area - Procedure is not standardized NEW! - Kinematic models will benefit areas with sufficient GPS data
