Answer to Question 1

ANSWER: A successful answer should include at least three of the following issues:
- The Campi Flegrei is an active resurgent caldera.
- The area has shown frequent and dramatic rising and sinking over a long period.
- The caldera is populated by two million people, making the potential loss of life extreme.
- Evacuation of the area would take considerable amounts of time due to the size of the population and available transportation.
- Past eruptions have deposited enough ash in nearby areas to collapse almost any roof.
- Previous eruptions have involved rhyolitic pyroclastic flows, which are extremely hazardous

Answer to Question 2

ANSWER: Volcanic ash will collect on rooftops and present other hazards to travel and people in both locations. The danger to a home will depend on the ash piling up on the roof, creating a danger of collapse. The danger is greater if the ash is wet. Either volcano can produce rain as a side effect of the eruption. Mt. Rainier is in an area that has a lot more snow, so this danger is a larger concern there.
