Welcome to Science 10-7 Get out your Locating an Epicenter Lab and open your book to page 205. Answer the MORE TO EXPLORE question on your lab sheet. **Page 170 will also be helpful** Today’s Schedule 1. Review Lab 2. Question of the Day 3. Notes/Discussion on EARTHQUAKE 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. Tsunami Animation Asian Tsunami Path of the Tsunami

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
