Natural-neighbor (n-n) isoseismals are proposed as a new tool that solves the centennial problem of drawing objective and reproducible isoseismals from earthquake damage sparsely observed in a region (felt reports). The algorithm uses the n-n coordinates for weighting, interpolating, and contouring the felt reports. In our computer implementation, at each step, the surface of irregularly distributed observations is partitioned into a unique set of Voronoi polygons computed on a fine regular… Expand
