QUAKE LASTS 20 SECONDS

Scores Awakened As Earth Shimmy Is Felt In This City

First shock at 5.40

Chimneys cracked in Anacortes; Quakes severe in Victoria; Dishes rattled at Everett

An earthquake strong enough to awaken scores of Mount Vernon residents was felt here between five and six o’clock this morning. The tremblor lasted about twenty seconds. The quake was of such intensity that objects in many homes were moved., it was reported to the Daily Herald today.

The quake was one of the rocking vibration variety from north to south, concluding with an east and west jerk, several who have gone through quakes reported today.

Scores were awakened by the quake, while others who had already risen said their houses rocked similar to a boat on the ocean.
