• many occur around ‘ring of fire’ surrounding the pacific
• most powerful earthquakes are usually associated with convergent or conservative plate boundaries

Question 2

describe volcano distribution

Answer 2

• most active volcanoes occur at or near to plate boundaries
• many ( about 75%) occurrences close around ‘ring of fire’
• volcanoes occur at convergent and divergent plate boundaries
• they can also be found at hot sports in the middle of plate like Hawaii in the central pacific

Question 3

describe tsunami distribution

Answer 3

• over 70% of tsunamis occur around the pacific ocean ( 15% mediterranean sea, 9% Caribbean sea and Atlantic ocean, 6% Indian ocean )
