1.2C impacts on hazards

• Convergent margins:

  • Oceanic-Oceanic: Frequent earthquakes, and violent eruptions from curving chain of volcanic islands.  
  • Continent-Continent: Infrequent major earthquakes distributed over a wide area. 
  • Oceanic-Continent: Frequent large earthquakes and violent eruptions. 
• constructive margins:

  • Oceanic-Oceanic:  Minor, shallow earthquakes.Continent-Continent: Basaltic volcanoes and minor earthquakes. 
• conservative margins:

  • Oceanic-Continent: Frequent, shallow earthquakes, but no volcanic activity. 
• collision zone = Collision zones are cut by huge thrust faults that generate shallow, high-magnitude earthquakes
