October 19, 1873 - A slight shock was felt about 2 P. M. at Seattle, W. T., and "at 4 o'clock clouds of smoke were seen pouring from the highest peak of Mt. Rainier."

November 22, 1873 - A shock was felt along the Pacific Coast and vicinity, from Portland, Oregon, to San Francisco ... It was most violent at Crescent City, California, and Port Orchard, Oregon ... At the former place nearly every brick building suffered more or less damage from cracked walls and falling chimneys. It was quite heavy at various points in the Coast Range of mountains, the severity diminishing north and south from the neighborhood of the State boundary line. The duration is stated at 20 to 30 seconds, and the time a few minutes past nine P. M. The direction appears to have been from a point between north and northeast ... At Albany, Oregon, two shocks were reported, and at Roseburg, Oregon, a "roaring" was also heard.

December 17, 1873 - A smart shock, followed by a rumbling noise, between 11 and 12 P. M., at Victoria, Vancouver Island.

December 20, 1873 - A shock in the night, lasting 10 seconds, at Victoria, Vancouver Island.
