X. On the British earthquakes of 1889

If the disturbed area be of small dimensions, and if its boundary be approximately circular or slightly elliptical in form, it is assumed that the centre of the area coincides very closely with the epicentrum of the earthquake. During the year 1889 there were at least five earthquakes whose epicentra were situated within the area of the British Islands. 1.Edinburgh Earthquakes ,January 18.—(a .) First shock about 4 h. 10 m.
