• liquefaction - When shaking cost lose material in soil to mix with a ground water
• Earthquake induced ground subsidence - Is the lowering of the land due to various causes, one of which is the earthquake on the fault line,
• tsunami - the word tsunami is a Japanese word that means Harbor wave
• Landslide - May happen during or after an earthquake, when a weekend section of the land falls off, primarily due to gravity
• seismometer - it’s an instrument used to measure movement in the earth surface
