Global Disaster Management: Volcanic Eruptions

This research guide is a starting point for research into the management of global disasters. It supports Pitt classes and workshops like - Building Community Resilience to Global Hazards, as well as the Hazard SEES Team members and their research.

Overview

Volcanoes

Lava erupting from a volcano's cone.

A volcano is a mountain that opens downward to a reservoir of molten rock below the surface of the earth. Unlike most mountains, which are pushed up from below, volcanoes are vents through which molten rock escapes to the earth’s surface. When pressure from gases within the molten rock becomes too great, an eruption occurs. Eruptions can be quiet or explosive. There may be lava flows, flattened landscapes, poisonous gases, and flying rock and ash that can sometimes travel hundreds of miles downwind.

Because of their intense heat, lava flows are great fire hazards. Lava flows destroy everything in their path, but most move slowly enough that people can move out of the way.
