The Deadly Explosion at Lake Nyos in Cameroon
TLDR In August 1986, Lake Nyos in Cameroon experienced a massive explosion caused by a trapped column of carbon dioxide gas at the bottom of the lake, resulting in the death of 1700 people. This tragic event led to the investigation of other potentially explosive lakes in Cameroon, such as Lake Monoun and Lake Kivu.
Timestamped Summary
00:00
In August 1986, Lake Nios experienced a massive explosion that resulted in a 328-foot-tall cloud of death.
03:50
In August 1986, Lake Nios in Cameroon experienced an explosion that resulted in a cloud of death, killing 1700 people and spreading through multiple villages, and scientists were brought in to investigate the cause, which turned out to be carbon dioxide.
07:07
Lake Nyos was formed thousands of years ago when magma rose to the surface and caused a huge explosion, creating a volcanic crater lake with a trapped column of CO2 gas at the bottom.
10:39
In lakes with seasonal temperature changes, gas exchange occurs naturally, but in Lake Nyos and other lakes in Cameroon where the temperature is consistently warm, the trapped gas bubble from the magma shaft continues to grow without any turnover, eventually leading to a potential explosion triggered by external factors like a rock slide or earthquake.
13:55
Lake Nyos is not the only lake in Cameroon that has the potential to explode due to trapped gas bubbles, as Lake Monoun and Lake Kivu also pose a threat, with Lake Kivu being particularly dangerous due to its depth and the large population living around it.
17:03
Lake Nyos has made progress in reducing CO2 levels since the installation of a pipe in 2001, but there are still other exploding lakes around the world, such as Lake Kivu and Lake Quilotoa, that pose a threat and may require similar interventions.

Mayan calendars function in a circular concept of time and are used for everyday planning, religious ceremonies, and agricultural purposes, and can be purchased in bookstores in Guatemala.
