1 GEOL 108 - Crises of a Planet Lab 6 - Landslides and Mass Wasting Oct. 9 - 12, 2012 Department of Earth Sciences

2 REVIEW | 2 QUIZ 4 REVIEW Mauna Loa Mauna Kea a.What is the approximate elevation at the peak of Mauna Loa? Mauna Kea? b.Is Mauna Loa a shield, composite, or stratovolcano? c.Why aren’t lahars a major concern on Hawaii in comparison to Mt. Rainier?

3 Department of Earth Sciences REVIEW | 3 QUIZ 4 REVIEW Path of hypothetical flow Bonus: What is the name of the Hawaiian fire goddess of volcanoes?

4 Department of Earth Sciences LANDSLIDES AND MASS WASTING | 4 LAB 6 - LANDSLIDES AND MASS WASTING Investigate landslide properties Relate landslides and wildfires Measure angle of repose and compare the angle for different materials

5 Department of Earth Sciences LANDSLIDES AND MASS WASTING | 5 LANDSLIDES Different situations create different types of landslides, which are given unique names by geologists. Hillside creep, rock fall, slump, etc.

6 Department of Earth Sciences LANDSLIDES AND MASS WASTING | 6 LANDSLIDES Moisture increases risk for landslides

7 Department of Earth Sciences LANDSLIDES AND MASS WASTING | 7 LANDSLIDES Fire can make slopes more susceptible to slides

8 Department of Earth Sciences LANDSLIDES AND MASS WASTING | 8 TYPES OF MASS WASTING

9 Department of Earth Sciences LANDSLIDES AND MASS WASTING | 9 ANGLE OF REPOSE Angle of repose of different materials varies
