This red-colored Victorian wood-frame home in Ferndale was damaged severely. The horizontal shift of the house is seen by the relative position of the house and the steps (still standing). The wooden skirting (on its side) indicates the original height of the house above ground level and its horizontal shift. The main floors of older Victorian homes were typically elevated on post and pier foundations, as much as 3 to 4 feet above the ground. Since these homes were not tied to the foundation, they were particularly vulnerable to earthquake shaking. Image Credit: Lindie Brewer.
