A) The mayor of the community is concerned about possible future eruptions and what hazards might be anticipated during an eruption
Assume that a future eruption would most likely erupt the same magma composition as during past eruptions. A consultant warns that such a future eruption will be highly explosive and would threaten large areas of the city; the city would be buried by pumice and devastated by pyroclastic flows. You are asked to give a second opinion. Do you agree or disagree with the consultant?
a. I agree with the consultant
b. I disagree with the consultant
(b) Please explain the reasoning behind the answer you selected, citing supporting evidence from your textbook.
a) B
b) The properties of eruptions of a mafic magma, summarized in the answer to question 2, are inconsistent with the consultant's warning. Instead, a nonexplosive eruption is expected and the greatest hazard will be from far-traveled lava flows.
