      • Earthquakes
        • Hardly Noticed

        • Reservoir Construction
        • Oil and gas production
        • Noticed when magnitude is high enough that people suffer
      • Volcanoes
        • Fast-moving lava can kill people
        • Falling ash can make it hard for people to breathe

          • Normal
          • Reverse (thrust)
          • Strike Slip
      • Volcanoes
        • Can cause change in weather like rain, thunder and lightening
        • Effect the climate, making the world cooler
        • Inside earth's core there is red hot liquid called magma.
        • Happens when magma rises to surface of earth
