Not-so Natural Disasters Part 1

We all know that natural disasters can be caused naturally, but evidence has shown that they can be man made, Tesla made an earthquake machine in the 19th century, Avalanches can be triggered with explosives and Weather can be influenced by man. We will be covering these points in Part 2. For now we will be explaining how some natural Disasters occur naturally.

Volcanoes:

Caused by a build up of magma rising up from the mantle. The heat melts through the Earth's Crust and the magma comes to the surface as lava. The volcanoes are built up of layers of ash and lava.

Earthquakes and Tsunamis:Caused by the release of huge amounts of energy when two or more tectonic plates slide past one another. A magnitude 8 earthquake releases the same amount of energy as 1 billion tons of TNT or 67,000 Hiroshima Bombs. The two plates collide and eventually buckle and 'jump' when they can't take the strain anymore. This releases the energy and it travels through the ground or water to cause an Earthquake or Tsunami.
