Earthquake Hazards: Building Design and Construction, and Liquefaction
Building Design and Construction
strength and flexibility of materials and design
wood houses are generally very safe
size/proportions of the building
single-family homes generally have a low and squat geometry
however, if you shake long enough, or is the building is on soft ground, even a wood-framed building will fail
this often means the building fell off its foundation
Liquefaction
shaking causes unconsolidated soils and sediments to liquify
ground loses cohesion and flows
buildings fall down, can remain intact
soil/sediment grains are touching in many places
little space between grains so the ground is strong
vibrations wiggle the grains, resulting in an increase in water pressure
space between grains increases
grains can move easily so water can flow
as soon as shaking stops, water pressure decreases
grains touch and soil becomes firm again
