These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Primary impacts are immediate and caused directly by the tectonic hazard.
  2. Secondary impacts are indirect impacts and occur in the hours, days and weeks after the hazard.
  3. There is a range of reasons why primary and secondary impacts may differ between two volcanic eruptions.
  4. Different indicators can be considered to assess the significance of primary impacts and secondary impacts.

Keywords

  • Primary impact - the immediate impacts of a tectonic hazard which are directly caused by it

  • Secondary impact - indirect effects that occur as a consequence of a tectonic hazard’s primary impacts

Common misconception

Impacts of volcanic eruptions are always more severe in developing and emerging countries than in developed countries.

A lot depends on the eruption type and factors such as population density. Economic impacts are often highest in developed countries because of the higher value of the property impacted by the eruption.

The ArcGIS Geography Visualiser is a fantastic tool for exploring volcanoes and the areas around them, while ArcGIS Online features layers that identify key aspects of eruptions, for example hazard risk zoning and evacuation routes.
