Felt like house settled. Loud earth noises heard. Fifteen miles north of Grand Coulee a farmer reported one crashlike shock. He went outside and then felt another. Disturbed a flock of birds near his home.
Earth noises heard by many before shock.
Motion bumping, like hammer blows. Monroe.-Felt by and awakened all. Windows and doors rattled. Moderate earth noises heard before shock. Started with barely perceptible motion followed by sudden jolt from south-north.
