Weakened structures in the communities hit by the April 19 earthquake were further damaged. At Winters, where the damage was most severe, many buildings that withstood the April 19 shock were leveled. Not one building on Main Street was left habitable. At Esparto, every brick chimney fell and wood-frame buildings were wrenched out of shape. Many chimneys were wrecked at Sacramento and Woodland, but additional loss was slight at Dixon and Vacaville. The area shaken at MM intensity VIII or larger was about 890 km2, but the general felt area was about the same as that of the April 19 shock.
