A 2021 paper estimated that bottom trawling contributed between 600 and 1500 million tons of carbon dioxide a year by disturbing carbon dioxide in the sea floor – emissions approximately equivalent to those of Germany, or the aviation industry. [3] [4] [5] However, these values are highly uncertain and have been criticized as overestimates.
The eruption triggered the sudden release of about 100,000–300,000 tons of carbon dioxide (CO 2). [ 2 ] [ 3 ] The gas cloud initially rose at nearly 100 kilometres per hour (62 mph; 28 m/s) and then, being heavier than air, descended onto nearby villages, suffocating people and livestock within 25 kilometres (16 mi) of the lake.
Lake Nyos, the site of a limnic eruption in 1986. A limnic eruption, also known as a lake overturn, is a very rare type of natural hazard in which dissolved carbon dioxide (CO 2) suddenly erupts from deep lake waters, forming a gas cloud capable of asphyxiating wildlife, livestock, and humans.
Water vapour is consistently the most abundant volcanic gas, normally comprising more than 60% of total emissions. Carbon dioxide typically accounts for 10 to 40% of emissions. [4] Volcanoes located at convergent plate boundaries emit more water vapor and chlorine than volcanoes at hot spots or divergent plate boundaries.
After various unsuccessful dives and spotting signs of bottom trawling on the seafloor, they feared that it might have been destroyed altogether. Then, they discovered it: a rich marine animal ...
Lake Nyos (/ ˈ n iː oʊ s / NEE-ohs) [1] is a crater lake in the Northwest Region of Cameroon, located about 315 km (196 mi) northwest of Yaoundé, the capital. [2] Nyos is a deep lake high on the flank of an inactive volcano in the Oku volcanic plain along the Cameroon line of volcanic activity.
Mazuku forming in a low morphological depression on the foothills of Mt. Amiata, Italy, where CO 2-rich fog accumulates in a ditch. Mazuku (Swahili for "evil winds") are pockets of dry, cold carbon dioxide-rich gases released from vents or fissures in volcanically and tectonically active areas, and mixed with dispersed atmospheric air and accumulating in typically low-lying areas.
Niland Geyser (nicknamed the "Slow One" [2] and formally designated W9) [3] is a moving mud pot or mud spring outside Niland, California in the Salton Trough in an area of geological instability due to the San Andreas Fault, [4] formed due to carbon dioxide being released underground. It is the only mud pot or mud volcano known to have moved so ...
