2. Reminders Online Test Due: Thursday Ch. 8 Test: Thursday Projects Due: October 22 1. Relationship between plate boundaries, EQs, and volcanoes. 2. Characteristics of the 3 seismic waves 3. How to read a seismogram 4. What an epicenter is and how to locate one 5. How to rate EQs on the Richter Scale 6. The difference between a focus & epicenter 7. How EQs cause tsunamis & how tsunamis travel.

3. 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.

4. I. Earthquake Hazards Besides violent shaking, what are some other hazards caused by EQs? Tsunamis, aftershocks, liquefaction

6. 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 - Ultimate Tsunami –

7. 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.

8. 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.
