Chimborazo
The summit of Mount Everest is higher above sea level, but the summit of Chimborazo is widely reported to be the farthest point on the surface from Earth's center, with Huascarán a very close second. The summit of the Chimborazo is the fixed point on Earth that has the utmost distance from the center – because of the oblate spheroid shape of the planet Earth, which is "thicker" around the Equator than measured around the poles. Chimborazo is one degree south of the Equator and the Earth's diameter at the Equator is greater than at the latitude of Everest ( above sea level), nearly 27.6° north, with sea level also elevated. Despite being lower in elevation above sea level, it is from the Earth's center, farther than the summit of Everest ( from the Earth's center). However, by height above sea level, Chimborazo is not the highest peak of the Andes.
National Polytechnic School (Ecuador)
In Ecuador, the National Polytechnic University department looks to the monitoring of the volcanic activity in this andean nation.
Cotopaxi is a stratovolcano in the Andes Mountains, located about south of Quito, Ecuador, South America. It is the second highest summit in the country, reaching a height of . Some consider it the world's highest active volcano, while others give this status to the considerably higher Llullaillaco, which most recently erupted in 1877 and is one of Ecuador's most active volcanoes. Since 1738, Cotopaxi has erupted more than 50 times, resulting in the creation of numerous valleys formed by lahars (mudflows) around the volcano.
