Kane's Presentation

  1. 1. Volcanoes and earthquakesAt the Earths surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displacedsufficiently to cause a tsunami. Earthquakescan also trigger landslides, and occasionally volcanic activity.
  2. 2. Volcanoes and earthquakes
  3. 3. Volcanoes and earthquakesWhen thick magma and large amounts of gasbuild up under the surface, eruptions can beexplosive, expelling lava, rocks and ash into theair. Less gas and more viscous magma usuallymean a less dramatic eruption, often causingstreams of lava to ooze from the vent.
