Houses need protection from earthquakes {earthquake hazard} {seismic hazard}.
foundation
Houses with concrete slab foundations have no cripple walls or posts and typically already have anchors. Foundations can have anchors and anchor bolts or steel plates can attach sill plate to foundation. Foundation wood studs {cripple wall} can raise bottom floor higher above ground and create crawl space. Cripple walls can have plywood or diagonal wood strengthening. Concrete blocks with wood posts {pier-and-post foundation} can raise bottom floor higher above ground and create crawl space. Posts can have plywood or diagonal wood studs for bracing. Concrete blocks, stones, or bricks can be foundations. Brick and concrete-block masonry can have steel reinforcing bars in the grout.
other
Masonry walls have bricks, clay tiles, stones, concrete blocks, and adobe and need reinforcement with steel bars. Rooms over garages need bracing around garage door {garage door}. Water heaters {water heater} need a bracing strap attached to wall studs, to prevent tipping. Chimneys {chimney} need bracing.
soil
Earthquake shaking can cause soil liquefaction. Sloping soils can have landslides.
