- Distribution of Tectonic Hazards
- Tectonic Hazard - natural event that has the potential to threaten both life and property
- uneven distribution across the globe and can happen at any plate margin
- earthquakes can also happen where the Indo-Australian plate collides with the eurasian Plate - a collision zone
- Intra Plate Earthquakes and Volcanoes
- Hotspots - hot mass of rising heat under a weakness in a plate, magma rises to the surface e.g the Hawaiian Islands in the pacific
- isolated plumes of convecting heat in the mantle rise towards the surface generating basaltic volcanoes - the plume is stationary although the tectonic plate moves
- continuing plate movement over time produces a chain of volcanic islands
- Earthquakes can happen in mid-plate settings, usually associated with ancient fault lines being reactivated by tectonic stresses - zones of weakness are created as plates move and stresses increase
- Tectonic Hazard - natural event that has the potential to threaten both life and property
