Tunguska Event

[LATE]


What is a natural hazard?
The word natural means “of or pertaining to nature or the universe” and the word hazard means “something causing unavoidable danger, peril, risk, or difficulty” – From Dictionary.com.

Natural hazard is an unavoidable danger caused by nature. There are many types of natural hazard in our world. Some are rare and some are common, examples of natural hazards are tsunami, hurricane, landslides and earthquakes. They are unavoidable but there are ways to lessen the damage from these disasters. Human invents many tools to be able to try to predict the time and location of the disasters. But we are a long way away from trying to control them.

Tunguska Impact, An Object From Space.

The Tunguska Impact is one of the rare natural disasters. It is an object from space that has not evaporated in the Earth’s atmosphere but exploded 4 miles above the surface. You may suspect why this doesn’t happen everyday. In fact is there are many asteroids that hit Earth everyday, but most of the asteroid is evaporated in the Earth’s atmosphere. The Tunguska asteroid is one of the larger kinds. Scientist suggests that if there is an asteroid of a larger size, there could be a dramatic climate change in the world. The damage of the asteroid has flattened many trees in the area, if the asteroid has struck somewhere else than Siberia, there would be many casualties and damage.

How and Why it Happen?
Nothing in this universe is predictable. There come a certain time where there would be an object orbiting close to Earth or even hit it. The chances are meek but it is possible. This asteroid has orbited and Earth is in its route. So the asteroid hits Earth, but is not evaporated by the atmosphere. It did still explode though, if it had not explode, it would have the destructive power of 60 nuclear arms in the current world.

After Effects and Damage -

The effect of the asteroid is it has flattened 80 million trees of over 2,150 square kilometers. There was no casualty due to the isolated part of Russia. The damage that it has been done to the nearby village could not receive the aids from Moscow. They do not have the money to fund an expedition to Siberia. Siberia is a very remote part of Russia, so therefore no expedition was created. This impact was the largest impact of the century. As Russia was a LEDC country, the aids were hard to be given. The technological improvements were poor and the air technology was still in development. Most damages were on forest, nearby villages and hunters.
