Animals will mass-enter human spaces quickly if their habitats are destroyed, and they generally wreak havoc on the belongings of underprepared people. If you see a stampede of deer coming from one singular place, lock your doors.
Steaming Lakes
Unlike geyser pools, steaming lakes present an even more devastating threat for those who choose to mess with them. If you’re close to a volcano, or any active volcanic surface for that matter, chances are all the surrounding groundwater will intermittently bubble and swell, releasing steam. This is the precursor to an event called a “limnic eruption,” which is when a body of water surrounding a volcano literally explodes due to a buildup of carbon dioxide under the surface.
