  4. WHAT MAKES A VOLCANO ESPECIALLY DANGEROUS • Location and a large explosivity index (VEI) combine to make some volcanoes especially dangerous.

  5. LOCATION NEAR CITIES MAKES SOME VOLCANOES VERY DANGEROUS An eruption at some locations is certain to be devastating to people, their property, their health, the community infra-structure, the environment, and the economy.
