Briefly summarize at least 4 major volcanic hazards. Describe the level of risk from most dangerous to least dangerous to human life. For each hazard indicate where the hazard is located relative to the volcano (on the volcano slopes, anywhere within several km of the volcano, anywhere within thousands of km of the volcano, in river valleys near the volcano, near bodies of water near the volcano, etc.) and consider if the probability of the hazard is very low, low, medium, high, or high, within the danger zone of the hazard.

Question undoubtedly has range of answers that could be acceptable in this question, but the question is meant for students to analyze the hazard from what they have learned in this chapter. Question would best be answered with a matrix, similar to below (question might even be worded that way, telling students to answer in a matrix).

Hazard

Danger

Location

Probability

Supervolcano caldera

extreme

continental scale

very low

Pyroclastic flow

very high

volcano slopes

high (on comp. volc)

Explosion/rock aval

very high

volcano slopes

high (on comp. volc)

Lahars and mudflows

high

river valleys near volc

high (on comp. volc)

Tsunami

high

coastal zone near volc

low to moderate

ash inhalation

moderate

10s to 100's km from volc

modest

lava flows

low

volcano slopes
