HAZARDS

Question of the Day• You live in the beautiful islands of Hawaii. An EQ

strikes hundreds of miles away off the coast of Alaska, but your life is still in danger. Why?

• Underwater EQs can trigger Killer Waves known as tsunamis that can travel for many miles at speeds close to 1,000 km/h.

I. Earthquake Hazards• Besides violent shaking, what are some other

hazards caused by EQs?

• Tsunamis, aftershocks, liquefaction

II. Tsunami• What is a tsunami?

• A wave that travels in all directions created by an underwater EQ.

III. Aftershock• What is an aftershock?

• Smaller EQs that occur after a main EQ. Aftershocks can happen hours, days, weeks and even months after an EQ.

IV. Liquefaction• Where do most EQS occur?

• Plate Boundaries

• Where are most plate boundaries?

• Along coasts

• What is the ground composed of on coasts?

• Mostly sand

• What is liquefaction?

• When shaking from an EQ liquefies the sandy soil near coasts.

IV. Liquefaction

• Liquefaction Flash Animation

• Seattle harbour liquefaction
