It was accompanied by the loud rumbling noise resembling the passing of a heavy waggon, and caused some shaking of furniture. It appears to have been felt and heard over a considerable area. The record by my large horizontal pendulum showed a single nearly sudden dip to the west of 3.6mm.

No certain signs of preliminary tremors could be detected upon the record. It seems important (cf. Milne, “Earthquakes,” p. 309, 4th ed., 1898) that for some days previously there had been a gradual, general dip of the level to the east, the mean distances of the hourly readings from the reference base-line, measured from east to west, being:—
