Which of the following is NOT a way in which a volcano's history indicates the level of hazard it poses to nearby population centers?

B) Average time between eruptions
C) Abundance of felsic pyroclastic materials in its deposits
D) Age of the oldest volcanic layer present
Felsic Pyroclastic
Materials produced by explosive volcanic eruptions that are rich in silica and comprise various types of volcanic ash, pumice, and other particles.
Volcanic Layer

Final Answer :
D
Explanation :
The age of the oldest volcanic layer present does not directly indicate the current level of hazard a volcano poses to nearby populations. It provides information on the volcano's age but not on its activity pattern or potential for future eruptions, which are more directly related to assessing hazards.
