systems and prioritization structures
• scenario choices; delineation; (model type choice)
• Conceptual level: understanding of the causal structure
• Model (type) choice; model structure; data sources/needs
• Model level: sufficiently adequate representation of the causal

The map shows the location of the damaging earthquake that struck yesterday afternoon. Most movement took place along the fault shown in green.

From the recorded data we obtained nearly 120 FPS of the earthquakes and assigned them with the
quality factors. We grouped the earthquakes into several groups according to their geographical
locations, and investigated the obtained results in each group separately. The overall results in the study
area show the dominating normal type of faulting and the N-S

The first map shows cloud cover measurements at a few stations in Iceland, along with information about cloud type and lowest cloud altitude (see following diagram). This information can be useful in evaluating the quality of the forecast.
Cloud cover observations are made every three hours at a few stations in Iceland. The latest observation is shown
