Volcanoes Incident Management

Incident Management Guidelines

A volcano is a mountain that opens downward to a reservoir of molten rock below the surface of the earth. 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. Because of their intense heat, lava flows create significant fire hazards and can destroy all structures in their paths. Ash flows can occur on all sides of a volcano, and ash debris can fall hundreds of miles downwind of the volcano. Dangerous mudflows and floods can occur in valleys leading away from volcanoes, striking with little warning. The common risks that accompany volcanic eruptions include earthquakes and tsunamis, mudflows and flash floods, landslides and rockfalls, and ashfall and acid rain.
In the event of a volcanic eruption occurring, the following points should be addressed:

Hurricanes and Tornadoes Incident Management

Incident Management Guidelines

A hurricane is a type of tropical cyclone, which is a generic term for a lowpressure system that generally forms in the tropics. It is defined as an intense tropical weather system of strong thunderstorms with a welldefined surface circulation and maximum sustained winds of 74 miles per hour (119 km/h) or greater. Tropical storms can also produce significant damage and loss of life, typically due to flooding. A tornado is a violently rotating column of air that is in contact with both a cloud base and the surface on the earth. Tornadoes come in many sizes, but are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris. Most tornadoes have wind speeds of 110 miles per hour (177 km/h), are approximately 250 feet (75 m) across, and travel a few miles before dissipating.
In the event of a hurricane or tornado incident occurring, the following points should be addressed:
