WASHINGTON AND OREGON (105th MERIDIAN OR PACIFIC WAR TIME) January 9: 04:28:03*. Yakima, Washington (press), "Houses in Yakima were shaken today. Several reports have been received that windows in homes were shaken and dishes rat- tled as if from an explosion." January 28: 23:30. Chelan Falls, Washington. Short, slight shock felt. March 5: 06:00. Dallas, Oregon (press), "Dallas and a district of some eight or ten miles around the city apparently were visited by a noticeable but not destructive earthquake shock about 06:00 a.m. Sunday. Many described it as so marked that they thought for an instant a car or truck had crashed into their homes. Apparently about four out of five homes situated in all parts of the city noticed the shock; although it came at an hour and a day when most people were still asleep. An earlier shock was reported by a much smaller number around 2:30 or 3:00 the same morning. There was no damage of any kind reported. Many at first thought it was heavy cannonading or an explosion. The absence of news reports from other sections indicated that the disturbance was local or at least was more severe here than else- where in the state." March 30: 20:30. Clear Lake (Eatonville), Washington. Motion rapid, brief, very dis- tinct. Felt by many in the Nisqually Power Plant. Direction NE. Rattled windows and doors. March 31: 14:15. Olympia, Washington.

Numerous Tacomans telephoned the press to report being awakened by the tremors. Some said the second tremor was more notice- able than the first, rattling dishes, swinging chandeliers and other unsecured objects.
