  1. Welcome to Science 10/12 • Update your grade sheet.

  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

  5. 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 –

  6. 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.

  7. 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.

  8. IV. Liquefaction • Liquefaction Flash Animation • Seattle harbour liquefaction

  9. Earthquake Project (Blueprint)Today you should be working on your drawing and your materials.1Spaghetti Stick = $501 marshmallow = $501 in. tape = $251 toothpick = $25
