October 9 - 8h a moderate shock (V), south to north, at Olympia, W. T.
October 10 - Between 1h and 2h three very light shocks (III), each of about one second duration and separated by an interval of six seconds, at East Portland, Oregon (U. S. Weather Review).

The principal shock occurred at 22h 40m, 120th meridian time, and was felt as far south as Olympia, where the motion was east-west and was sufficient to arouse sleepers.
