Historical Examples of isoseismal
Outside the isoseismal 4, the earthquake was observed at several places.
An isoseismal line is a curve which passes through all points at which the intensity of the shock was the same.
That isoseismal along which the decline of energy is most rapid was called by K. von Seebach a pleistoseist.
Within the isoseismal 3, buildings were more or less slightly damaged.
The only complete map of the isoseismal lines is that drawn by Professor Mercalli.
