Active volcanoes in Ecuador
The Geophysics Institute of the Polytechnic National School has quantified 27 volcanoes which are potentially active in Ecuador. These include the ones in the Galapagos Islands, Marchena, Cerro Azul, Fernandina, Santo Tomas, Alcedo, Darwin and Wolf. In the continent, there are seven volcanoes: Cayambe, Guagua Pichincha, Cotopaxi, Reventador, Sangay, Tungurahua and Potrerillos-Chacana.
Cotopaxi is a snowed stratovolcano which is 5897 meters over the sea leve, which when it reactivated, became one of the most active high volcanoes in the world. Historical data and geological register prove that it has presented very big rhyolitic eruptions, where lava has ran like a river. Because of its background, there is a need for the central governments to prepare and for decentralized autonomous governments to form committees in charge of managing risks
