9 Geohazards Which geohazards are related to plate boundaries ? HazardPlate Margin(s) What causes the hazard Earthquakes Effusive Volcanic Eruptions Explosive Volcanic Eruptions Landslides Tsunamis

10 Relate Geohazard to Plate Tectonics Which geohazards are related to plate boundaries ? On your table, write in pencil which plate boundary(s) the hazard is triggered by Earthquake Explosive Volcanism Effusive Volcanism Landslide Tsunami

11 ‘ Hot Spots Volcanics’ Throughout Geological Time

12 Hot Spots Not Associated With Plate Tectonics Hot spots and mantle plumes: Caused by rising plumes of deep mantle material Volcanoes can form over them (Hawaiian Island chain) Mantle plumes –Long-lived structures –Some originate at great depth, perhaps at the mantle-core boundary

13 The Hawaiian Islands http://www.edumedia-sciences.com/en/a99-hot-spot-volcanism http://www.classzone.com/books/earth_science/terc/content/investigati ons/es0810/es0810page03.cfm
