- An example of soil type: Liquefaction
- Some soil types are subject to liquefaction.
- The stream behind the garage saturated the soil with water.
- The earthquake shaking “floated’ the soil grains in the water and the soil was able to flow.
- This type of ground failure is called liquefaction.
- When special soil problems like liquefaction or landslides may occur, a geotechnical engineer should be hired for advice.
- In summary:
- The three things that affect how much earthquake force will reach a house are:
- Size of earthquake
- How far the house is from the quake
- What kinds of soils underlie the house
