At nighttime, ominous lightning flashes above erupting volcanoes light up the sky like a living nightmare. Now, scientists are closer to understanding volcanic lightning, which stems from both ash and ice. Below some amazing and recent pictures of this strange phenomenon captured during the latest eruptions of Anak Krakatau in Indonesia… And a short explanation on what creates them.
When hot, molten rock pushes its way up through the Earth’s crust and exits through to the surface, it often results in a volcanic eruption. These eruptions sometimes occur via slow and steady flows, but often show themselves in huge bursts of activity. When this latter case happens, a large amount of ash, dust, rock, volatile gases, and lava all are expelled in a very short period of time. While we might think of these as the major features of a volcano, there’s often a magnificent visual sight that accompanies these: volcanic lightning. Although not every eruption will produce this stunning light show, it’s been observed and recorded by humans for countless generations. Now, with our advanced understanding of physics and the physical sciences, we finally understand how it’s produced.
Lot of pics,

Realist - Everybody in America is soft, and hates conflict. The cure for this, both in politics and social life, is the same -- hardihood. Give them raw truth.
