There were two distinct slips in rapid succession, with continuous slight motion between them, the second being greater in amount and extending over an area which probably overlapped, even if it did not entirely include, that within which the first took place. The great slip reached nearly from Loch Ness to Inverness, and was greatest at a point about half-way between. The three chief after-slips resulted in an extension of this area...

The isoseismal 4 is 74 miles long from E. to W., 52 miles wide, and contains about 3020 square miles. The shock was a strong tremor, of mean duration about 3 seconds. The sound was heard by all the observers, and was compared to passing waggons, etc., in 79 per cent, of the records, thunder in 14, and explosions in 7, per cent. 3. 1883 JUNE 25, 2.7...

At a few places not far from the central area, two maxima of intensity in the principal vibrations were detected by careful observers and their evidence is confirmed by the Birmingham seismogram (Fig. 26). At a great distance — at Liverpool and Southport and in some parts of Ireland, for...
423. oldal - Leicester earthquake of 1893 leads to a somewhat similar conclusion. The epoch of maximum intensity of the sound preceded that of the shock at 19 places, which are, as a rule, near the ends of the longer axis of the disturbed area ; and coincided with it at 18 places, which are not far distant from the epicentre or shorter axis, and in two cases close to the ends of that axis.
443. oldal - ... the isoseismal 4 would contain about 40,000 square miles. Nature of the Shock. In its general features, the nature of the shock was nearly uniform throughout the disturbed area, and the following account (from Meyllteyrn, near Nevin) may be regarded as typical for a large part of the area. The shock began with a series of tremors, lasting 4 or 5 seconds, which merged gradually into a single series of principal vibrations of about 3 or 4 seconds' duration, these being succeeded by a brief series...
