Go to Weekly Lectures, open the folder for Week 9 and read the information posted there.
Go to Weekly Readings, open the folder for Week 9 and read chapters 10, 11, & 12 of Full Rip 9.0: The Next Big Earthquake in the Pacific Northwest.
Go to Weekly Videos, open the folder for Week 9, and watch two videos: Deadliest Earthquakes and Can Animals Predict Disasters?

Answer the following questions about Deadliest Earthquakes:

1. How do GPS measurements help scientists calculate stress that accumulates along faults? How is this information useful in predicting earthquakes? Be sure to explain what can be predicted based on stress accumulation, and what cannot.

2. In the video, what is the Holy Grail of Seismology?How could these measurements help scientists predict earthquakes?

3. What are mega-thrust earthquakes? Where do they occur?

4. How can silent earthquakes, or slow slip, help scientists predict larger earthquakes?

5. What is Shake Alert? How can the difference in the arrival times of P-waves and S-waves give people time to prepare for earthquakes? Is this type of early warning system currently being used in other countries? If so, what types of precautions does it allow for?

Compose your work in a word processing program (Microsoft Word, etc.) and submit it to me through Blackboard as Assignment 17.

This weeks videos are accessed through direct links, rather than downloading them through Blackboard. What does that mean for you? No long boring stretch of silence while you wait for the videos to download! But, on the downside, you have to watch some commercials.
