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 earthquakes.

Keywords

  • Magnitude - a measure of the energy released by an earthquake

  • Epicentre - the point on Earth's surface that is directly above where an earthquake happens underground

Common misconception

Tsunamis and landslides are primary impacts of earthquakes because they can cause massive damage to people and property.

Tsunamis and landslides are secondary impacts of earthquakes because they happen as an indirect result of an earthquake. For e.g, ground shaking destabilises slopes, making a landslide more likely, especially if there is then also heavy rain.
