Map of the July 18,1880(12:40 p.m.) earthquake, the historical earhquake that had the largesst number of reports.
Roman numbers are intensities. Squares represent locations of towns existing at that time. Solid circle is the
epicenter estimated at 14.5 N Lat., 121.6 E Long. Felt areas(in square kilometers) at Intensities X to V and their
calculated Ms values are:A(X)=5715sq. km(Ms 8.0); A(IX)=21050sq.km (Ms 7.9); A(VIII)=35544sq.km (Ms
7.8); A(VII)=63314sq.km (Ms 7.5); A(VI)=150116sq.km(Ms 7.3); A(V)=359521sq.km (Ms 7.1). Ms(ave)is 7.6.
