large seismic sea wave
landslides
reduction in strength of slope
fires
trees falling down
liquefaction
loosely packed water logged sediments lose their strength
physical reasons for impacts
nature of bedrock
type of ground/material
earthquake magnitude
strength of earthquake
human resons for impacts
