June 30 1908

The Tunguska Event - The biggest natural explosion in modern history.
There's good reasons why the reptilians have been underground.

"The Tunguska event, or Tunguska blast or Tunguska explosion, was an enormously powerful explosion that occurred near the Podkamennaya Tunguska River in what is now Krasnoyarsk Krai, Russia, at about 7:14 a.m. KRAT (0:14 UT) on June 30 , 1908.

The explosion is believed to have been caused by the air burst of a large meteoroid or comet fragment at an altitude of 3–6 mi above the Earth's surface. Different studies have yielded varying estimates of the object's size, with general agreement that it was a few tens of metres across."

"Although the meteoroid or comet burst in the air rather than hitting the surface, this event is still referred to as an impact. Estimates of the energy of the blast range from 5 to as high as 30 megatons of TNT , with 10–15 megatons of TNT the most likely—roughly equal to the United States' Castle Bravo thermonuclear bomb tested on March 1, 1954, about 1,000 times more powerful than the atomic bomb dropped on Hiroshima, Japan, and about one-third the power of the Tsar Bomba, the largest nuclear weapon ever detonated. The explosion knocked over an estimated 80 million trees covering 2,150 square kilometres (830 sq mi). It is estimated that the shock wave from the blast would have measured 5.0 on the Richter scale."

"An Irkutsk newspaper dated 2 July reported that, in a village more than 200 miles from the Tunguska river, peasants had seen a fireball brighter than the sun approach the ground, followed by a huge cloud of black smoke, a forked tongue of flame and a loud crash as if from gunfire.

All the villagers ran into the street in panic. The old women wept and everyone thought the end of the world was approaching.

Nearly 400 miles south-west of the explosion, at 7:17 a.m. on 30 June, a train driver on the Trans-Siberian express had to stop his train for fear of derailment due to the tremors and commotion. In towns 300 to 400 miles away, hurricane-like gusts rattled doors, windows and crockery. This was followed within minutes by shock waves which knocked down horses and hurled people working on boats into the river."
