## Resource

A limnic eruption, or lake overturn, is a super rare natural disaster where a lake suddenly releases a huge bubble of dissolved carbon dioxide (CO2) from its depths. This gas cloud can suffocate wildlife, livestock, and even people nearby. It happens when volcanic activity or a landslide disturbs the deep, CO2-rich water, causing it to rapidly rise and release the gas. Recognizing an impending limnic eruption can be tricky, but signs might include unusual lake bubbling, dead fish, or a sudden change in the lake's color. And if you see it, you'd better stay away from it. Preview photo credit: Dan Keck / Flickr https://www.flickr.com/photos/1406411... Animation is created by Bright Side.
