Residents as far away as Healdsburg, Santa Rosa and Napa reported feeling the shaker. “I actually heard the quake coming”, Ukiah resident Bailey Penzotti said. They reported shaking, but nothing falling off of walls or any damage as far as they knew.
Firefighters were battling a small wildfire nearby.
