Learning Objectives

An overview of the global distribution of tectonic activity and its link to plate movement and boundaries.
Large scale processes (convection, subduction and divergence) at constructive and destructive margins.
Resulting large scale features to include rift valleys and ocean trenches.
The concept of volcanic hotspots (for example Hawaii).
Processes which result in distinctive volcanic landscape features:
- Larger scale features to include shield volcanoes, stratovolcanoes, and caldera.
- Smaller scale features to include cinder cones, lava tubes and geysers.

Physical and human factors that increase vulnerability to tectonic hazards
Physical factors to include the magnitude of volcanic eruptions and earthquakes.
The characteristics and scale of pyroclastic flows, lava flows, lahars and ash clouds.
Social and economic factors that can increase vulnerability of communities in tectonic zones in countries at different levels of economic development.
Coverage must include one located example of a volcanic hazard and one located earthquake event.
