| dbo:abstract | El Campo Volcánico Oku o Macizo Oku es un grupo de volcanes en la Línea Volcánica de Camerún, ubicado en la región Oku del Altiplano Occidental de Camerún. El estratovolcán del Monte Oku se eleva a 3.011 m sobre el nivel del mar. El macizo tiene un diámetro de casi 100 km y contiene cuatro estratovolcanes principales: el Monte Oku, el Monte Babanki a 15 km al SO de Oku, Nyos y Nkambe. Las rocas en el macizo tienen edades desde hace 24,9 a 22,1 millones de años, pero se ha producido una actividad volcánica más reciente. El macizo está compuesto de roca riolítica y traquítica, y contiene muchos maars y conos de ceniza basáltica. El campo volcánico de Oku incluye dos lagos de cráter, el lago Nyos al norte y el lago Monoun al sur. El 15 de agosto de 1984, un terremoto y un deslizamiento de tierra desencadenaron una importante liberación de dióxido de carbono desde el lago Monoun, matando a varias personas. El lago Nyos está dentro de un maar formado por una explosión hace unos 400 años, y tiene unos 1.800 m de ancho y 208 m de profundidad. Hay un depósito de dióxido de carbono libre a baja temperatura debajo del fondo del lago, que se filtra en el lago a través de una tubería volcánica. El 21 de agosto de 1986, el lago Nyos liberó una gran cantidad de dióxido de carbono que mató al menos a 1.700 personas por asfixia, posiblemente provocada por un terremoto de fuerza 5 a lo largo de la , que se extiende por debajo del macizo. (es) The Oku Volcanic Field or Oku Massif is a group of volcanoes based on a swell in the Cameroon Volcanic Line, located in the Oku region of the Western High Plateau of Cameroon.The Mount Oku stratovolcano rises to 3,011 m above sea level. The massif has a diameter of almost 100 km and contains four major stratovolcanoes: Mount Oku, Mount Babanki 15 km SW of Oku, Nyos and Nkambe.Rocks in the massif have ages from 24.9 to 22.1 million years ago, but more recent activity has occurred. The massif is composed of rhyolitic and trachytic rock, and contains many maars and basaltic cinder cones. The Oku Volcanic Field includes two crater lakes, Lake Nyos to the north and Lake Monoun to the south.On 15 August 1984, an earthquake and landslide triggered a major release of carbon dioxide from Lake Monoun, killing several people. Lake Nyos is inside a maar formed by an explosion about 400 years ago, and is about 1,800 m wide and 208 m deep. There is a low-temperature reservoir of free carbon dioxide below the lake bottom, which seeps into the lake through a volcanic pipe.On 21 August 1986, Lake Nyos released a massive amount of carbon dioxide which killed at least 1,700 people by suffocation, possibly triggered by a force 5 earthquake along the Foumban Shear Zone, which runs under the massif.
