What the simulator shows

The simulator turns magnitude and depth into shaking intensity on the Modified Mercalli scale. By that estimate intensity VI, at which loose objects fall from shelves, reaches 76 km from the epicentre, and no town listed in GeoNames lies inside that circle.

This is a simplified model, not a damage report. Real effects depend on soil, buildings, terrain and the details of the event.
