Natural disasters are disasters that are caused by natural forces. Some examples are earthquakes and volcanic eruptions.
On 2nd May 2008, the Chaiten Volcano erupted again after about 9'500 years. It happened in southern Chile. The plates were pushing against each other causing the Nazca plate to go beneath the South American plate. The elevation of the volcanic eruption on 2nd May 2008 was 1122m (3,681 ft). Its eruption has caused the nearby town, Chaiten, to be engulfed with lahars and ash. The ash that has been produced caused much inconvenience in travel and agriculture in the neighbouring countries such as Argentina. The surrounding were all forced to cancel flights. It has also polluted part of the Atlantic Ocean.
The following six days after its eruption, the Chaiten Volcano pumped up large amounts of ash into the surroundings. The Chaiten Volcano has still been erupting since then. The Chilean government started an evacuation in the town, Chaiten. At the same time, they sent out the UK Natural Environment Research Council to the area where most of the falling ash were found. They were asked to evaluate the air quality and the chemicals found in the falling ash.
I think that scientists should build an instrument which can detect where and when a natural disaster such as a volcano would happen a few days before. When that is done, the government would be able to warn the people staying near that area to evacuate, allowing them to escape in time.
