Several buildings in Hongkong were slightly damaged.
In addition to the principal shock at 14h. 9m. other movements were felt as follows:
Time. Character. Approximate duration in seconds. 13d. 14 48 slight rumble. momentary. 16 9 slight shock. momentary. 16 11 slight shock. momentary. 21 27 slight shock. 5 22 36 moderate. 5 22 55 feeble. momentary. 23 10 feeble. momentary. 14d. 1 12 moderate; doors shaken 6 1 39 very slight, increasing to moderate; doors shaken. 2 51 5 20 very slight, rumble. 4 26 16 50 very slight, increasing to very pronounced shock, shaking of doors somewhat alarming. 7 slight shock. momentary. slight to moderate shock. 20 3 3The increased movement at 14d. 1h. 12m. suggested that the previous shocks were possibly precursors of a local earthquake. Telegrams were therefore sent to the Observatories at Manila, Taihoku, and Zikawei, asking them to give the origin of the disturbance, with a view to issuing local warnings if necessary. Replies from all three Observatories were received by 14d. 16h. The mean of the three estimations given by the above Observatories is latitude 26° N. and longitude 115° E. or about 250 miles N. by E. of Hongkong. The distances given by Shanghai and Taihoku, however, make the origin at Swatow.
It appears that the origin was a few miles to the north-west of Swatow.
Other shocks felt during the year were as follows:-
