Questions to answer

from the contour profiles

When finished, the five groups should combine results.

On each contour profile worksheet, the area between the PRE- and POST- profiles, can be shaded red to indicate the thickness and extent of the new lava flow along each profile. Determine the maximum thickness of the flow and indicate where any collapse areas are located.

Mark the location of the rumbleometer. Is it in a collapsed or uncollapsed area of the flow? What does this tell you about what happened to the rumbleometer? How did it not get buried by lava?
