1. Virtual Field Experience Earthquakes

2. Today you will be a....Seisomologist Seismologist: scientist who studies shaking motions of the earth How are earthquakes measured? The Richter Scale (measures the magnitude of an earthquake)

3. Time Travel Your mission is to travel time to study some of the most famous recorded earthquakes.

4. San Francisco (1906) Magnitude: 8 Epicenter: San Francisco Occurred on San Andreas Fault Fault slip visible on surface (very rare!) Fires after the earthquake caused most of the death toll

6. Assam-Tibet (1950) Magnitude = 8.5 Caused ground cracks and large landslides in the area Felt as far away as India (Assam is a Northeastern state of India) However, the epicenter was in Tibet

9. Chile(1960) Magnitude 9.5 Largest earthquake ever recorded $550 million in damage Triggered a tsunami that injured and killed people in Hawaii, Japan, and the Philippines Occurred where the subduction of Nazca Plate under the South American Plate took place

11. Rat Islands, Alaska (1965) Magnitude 8.7 Alaska had been a US state for 7 years at the time This earthquake triggered a tsunami of over 30 feet Reported in Hawaii and Japan Result of subduction of Pacific Plate under the North American Plate(Reverse Fault) Little damage reported (very remote area)

13. Tangshan, China (1976) Magnitude 7.5 Coal-mining town, so many people were underground when the earthquake occurred Boundary between tectonic plates in this part of the world is not clearly defined. The region is deforming(changing shape)by earthquakes instead of a steady process.

15. Sumatra, Indonesia (2004) Magnitude 9.0 Caused a powerful tsunami in Indian Ocean that greatly affected 12 Asian countries Epicenter was off the west coast of Sumatra (an Indonesian Island) We will never know the exact death toll because so many people were swept out to sea

17. Central Italy(August 24, 2016) Magnitude 6.2 Epicenter near Accumoli Caused by subduction of African Plate beneath Eurasian Plate As of September 29th, the death toll is 298
