Colima (volcano)
Volcán de Colima
The Colima consists of two surveys: the older and inactive Nevado de Colima ( 4330 m ), also called Zapotepetl, as well as the younger and very active Volcán de Colima ( 3850 m), which lies further south and also as Volcán de Fuego de Colima known is. He is the most active volcano in Mexico.
Location
The volcano Colima is located on the border of the federal State to Colima Jalisco, the Pacific coast is just ewa 100 km away. The city of Colima is located about 60 km ( straight line ) south of the mountain summit in the state of Jalisco.
Geology
In the late period of the Pleistocene a huge landslide took place that moved about 25 km ³ of debris up to 120 km and reached the Pacific Ocean. An area of about 2,200 km ² is covered by the rubble. Massive events of this kind seem to occur every few millennia. The current active cone is situated in a large caldera that was probably formed from a combination of landslides and large eruptions. In the late 1990s the two cones were wired with measuring instruments.
Volcanic activity
The Colima has a five- million-year history of volcanic activity and is counted by the UN to the 16 most dangerous volcanoes in the world. Since 1576 he broke out more than 40 times. In the previously known most violent eruption in 1913 was still in Guadalajara, 120 km away down ash.
In recent years, the surrounding villages had to be evacuated due to volcanic activities frequently. An eruption on 23 May 2005 was the most violent since 1991, on 4 June 2005, another outbreak took place, which reaches an altitude of 9 km threw ash into the atmosphere. It was thus the most powerful eruption of the previous two decades. Then, a restricted zone of 7.5 km was constructed and prepared the 300,000 inhabitants of the area for a possible evacuation. After a period of inactivity, the volcano came on January 6, 2013 again from an ash cloud.
Ascent
The ascent of Nevado de Colima is possible A runway road leads up to the weather station at about 4000 m in height; The summit can be reached by hiking boots. An ascent of the Volcán de Fuego often active de Colima is only permitted if accompanied by an experienced guide.
