Damage description: "Earthquake damage to the Andres Pico Adobe is very extensive, consisting of severe crack damage and partial collapse of some walls. Approximately one third of the south-end gable wall above the second floor collapsed, as did the chimney on the west wall above the roof line, the northwest comer of the kitchen, the northeast corner of the garage, and a section of garden wall along the north side of the patio. The north gable-end wall at the second-floor level is leaning outward approximately 3 inches and a large section of the exterior plaster separated from the adobe surface and fell, causing structural damage to the balcony. The east and west longitudinal walls have permanent out-of-plane damage with mid-span deflections of approximately 4 inches at the second floor joist level and at the wall top plate level. There is severe crack damage throughout the structure and evidence of moisture damage along the base of the walls which led to increased levels of adobe and plaster spall damage as well as partial collapse in some locations. The west longitudinal wall and northwest comer of the kitchen are examples of increased spalling of the adobe and partial collapse, respectively. Much of the cracking also resulted in large areas of spalled and delaminated plaster."
