Milne is the only source. He says: "1909 MAY 17. 9:20 a.m. Vancouver newspapers report a strong vibration was felt over all the western provinces at this time. Information comes from Winnipeg, Regina, and strangely enough from Prince Rupert. No major tremor was recorded at this time which could have been felt over such a wide area. It is suggested that little weight be placed upon these reports."
