In the Shadow
• In 1877 mudflows travelled 100km from the volcano burying nearby towns and villages including parts of Sangolqui
• Now over ¼ million people live in the Sangolqui and Los Chillos valleys
• These people live on top of old lahars (mudflows) that came from Cotopaxi

Ecuador Volcanic Activity Case Study
• Where is Ecuador and why are active volcanoes found there?
• What evidence is there of recent volcanic activity within Ecuador.
• What hazards are associated with this volcanic activity?
• Why do people continue to live in the Valley of the Volcanoes in the Ecuadorian highlands?
