An estimate for the town centre from magnitude, depth and distance, with the intensity equation USGS Did You Feel It? uses (Atkinson & Wald, 2007), on the Modified Mercalli scale. 3 of these reach intensity II or more in town, where people at rest start to notice. Ground conditions change it street by street. It describes the past, not a hazard.
