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

and even months after an EQ.
