The Volcanic Monster We Can't Find; 426 BCE Mystery Eruption

Описание: The largest explosive volcanic eruption to occur in the last 2500 years is seemingly missing. As, scientists have still not been able to find the exact volcano which caused it or even section of the world the eruption originated in. This video will discuss the drastic effects the 426 BCE mystery eruption had on ancient Greece (specifically Athens), and mentions a few possibilities on which volcanoes could be its eruption source.

Correction: Not 100% or all of the bacteria which causes typhoid fever is purportedly eradicated by sunlight within a few minutes. This is a mistake I made in this video. However, significant bacteria population reductions are achieved on surfaces for the associated bacteria with prolonged exposure to direct sunlight.
