Volcanic Hazards

Volcanic Hazards: Introduction

Volcanic hazards are any potentially dangerous volcanic process that put human lives, livelihood, or infrastructure at risk of harm. Several hazards may affect the area around the volcano, such as lava flows, pyroclastic flows, lahars, landslides or debris avalanches. Volcanic activity also produces hazards that can affect areas far from the volcano, such as tephra or ash falls, releases of gas, and tsunamis. Such hazards can impact areas hundreds or thousands of kilometres from the volcano, with the potential for significant health and economic impacts.

This ​A-Level Volcanic Hazards module will enable students to:

• ​Define what volcanic hazards are;
• Understand the global distribution of volcanic hazards;
• Identify the effects of volcanic eruptions;
• Enumerate some features and landscapes produced by eruptions;
• Identify the different hazards and warning signs for volcanic eruptions;
• Describe how to manage and mitigate volcanic hazards; and
• Identify ways we can prepare for volcanic hazards ahead of time.
