Secondary (a result of the primary hazards)

Question 1

primary hazards of earthquakes

Answer 1

Ground shaking

Crustal fracturing (when the movement causes the Earth’s crust to crack)

Question 2

secondary hazards

Answer 2

landslides and avalanches

liquefaction

flooding

Question 3

flooding

Answer 3

tsunami

Question 4

What is liquefaction

Answer 4

Affects poorly compacted sand and silt.
● Water moisture within the soil separates from the soil particles and rises to the
surface.
● This can cause the soil to behave like a liquid, which can cause building subsidence
or landslides.
