Ambato, Ecuador
Ambato lies in the main valley of the Central Cordillera, the highest of the Andean mountain ranges. The city itself is carved into the side of Cerro Casigana, the mountain that dominates the north end of the city. From Ambato, it is possible to see many snow-capped volcanoes including Cotopaxi, Tungurahua, Carihuairazo, and the largest mountain in Ecuador, Chimborazo. Tungurahua lies about 40 kilometers to the southeast. The threat of eruption from the volcano is constant. On May 16, 2006, Tungurahua erupted, covering the city with a thick layer of ash.
Tourism in Ecuador
Quilotoa it is a water-filled boiler and the westernmost volcano in the Ecuadorian Andes. The 3 km wide boiler was formed by the collapse of this dacite volcano following a catastrophic eruption 800 years ago, which produced pyroclastic flows and lahars that reached the Pacific Ocean, and spread in the air a deposit of volcanic ash along the northern Andes. The boiler has accumulated a depth of 250 m crater lake, which has a greenish color as a result of dissolved minerals. Vents are on the bottom of the lake and hot springs occur on the eastern flank of the volcano.
