1. Flow liquefaction occurs when the soil loses all of its strength and flows like a liquid. This is the most destructive type of liquefaction, and it can cause buildings to collapse, bridges to fail, and roads to buckle.
2. Cyclic liquefaction occurs when the soil loses strength and then regains it as the earthquake shaking continues. This type of liquefaction can cause buildings to settle unevenly, which can damage their foundations and cause them to collapse.
3. Lateral spreading occurs when the soil on a slope liquefies and spreads out, causing landslides. This type of liquefaction can damage buildings, roads, and other infrastructure.
All three types of liquefaction can be very dangerous, and they can cause significant damage to property and infrastructure.
