Ecuador
Ecuador's capital is Quito, which is in the province of Pichincha in the Sierra region. Its largest city is Guayaquil, in the Guayas Province. Cotopaxi, just south of Quito, is one of the world's highest active volcanoes. The top of Mount Chimborazo (6,268 m, or 20,560 ft, above sea level), Ecuador's tallest mountain, is the most distant point from the center of the Earth on the Earth's surface because of the ellipsoid shape of the planet.

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.
