Activity 10. Comparing the Mauna Ulu and Puu Oo Eruptions (Grades 9-12)

Months in 1983 and 1984. From Wolfe and others (1988).

Instructions: Use the graph to answer the following questions. Numbered solid blocks represent major eruptive episodes. Open, half-height blocks represent low-level activity.

1. For the time intervals shown, which eruption produced the greatest volume of lava?

2. What are the volumes for each eruption?

3. Calculate the rate of each eruption in m3/month and m3/hr.

4. Are the actual eruption rates higher or lower than those calculated in question 3?

5. Estimate the total erupted volume of the ongoing eruption of Kilauea Volcano. List all assumptions.
