Global Distribution of Tectonic Hazards

Question 1

Earthquake distribution

Answer 1

• Many earthquakes occur close too or at a plate boundary
• Many occur around the ring of fire (surrounding Pacific Ocean)

Question 2

What plate boundaries are the most powerful earthquakes found at?

Answer 2

Convergent or conservative

Question 3

What are intra-plate earthquakes?

Answer 3

Earthquakes that do not happen at plate boundaries
(often linked to hot spots or old fault lines

Question 4

Volcano distribution

Answer 4

• Most active volcanoes occur at or near to the plate boundaries
• Many occur around the ring of fire

Question 5

What plate boundaries do volcanoes occur at?

Answer 5

Convergent and divergent
(volcanoes can also be found at hot spots in the middle of plates)

Question 6

Tsunami distribution

Answer 6

• Tsunamis are caused by tectonic activity
• They occur due to activity at convergent boundaries
