With evidence so abundant, a new method of drawing coseismal lines becomes possible.    From Wordnik.com.  [A Study of Recent Earthquakes] Reference

The coseismal lines obtained in this manner are represented by the continuous curves in Fig. 62.    From Wordnik.com.  [A Study of Recent Earthquakes] Reference

The curves separating these zones would be coseismal lines corresponding to the times 5. 32-1/2, 5. 33-1/2, and.    From Wordnik.com.  [A Study of Recent Earthquakes] Reference

In the Hereford earthquake of 1896, the centre of the innermost coseismal line (Fig. 62) is close to the region lying between the two epicentres.    From Wordnik.com.  [A Study of Recent Earthquakes] Reference

There is thus an apparent increase in the velocity with the distance, but the accuracy of the coseismal lines is unequal to establishing this as a fact.    From Wordnik.com.  [A Study of Recent Earthquakes] Reference

If, however, the number of observations is large for the size of the disturbed area, the construction of coseismal lines may define approximately the position of the epicentre.    From Wordnik.com.  [A Study of Recent Earthquakes] Reference

Owing, however, to the inevitable inaccuracy of all the time-records, these different zones intrude on one another, and the coseismal lines have therefore to be drawn about half-way through the overlapping regions, special weight being attributed to the apparently more accurate observations.    From Wordnik.com.  [A Study of Recent Earthquakes] Reference
