When a volcano erupts, it make make many changes to its surroundings, the environment and the life of people living around it both,
positive and negative. Here are some examples of negatives affects that follows the eruptions of mountains such as
mount Tambora.
THE ENVIRONMENT
The immediate effects include the stench of sulfuric gas in the air, and the raised sea temperatures caused by the pyroclastic flow entering the water. Both of these effects will only last a very short while.
THE PEOPLE
Lots of people would also be left homeless. There would be a massive decline of the country's population due to whooping numbers of casualties from the hot lava and or the suffocating volcanic ash emmited, which is cause by inadequate information on the eruptions There will also be effects on the economy, depending on the area effected. If it is the financial district, than the wealth of the country will decrease.
There will also be a huge problem concerning 'Lahar', every time it rains. When the pyroclastic materials mix with large amounts of water, 'lahars' (which is a type of mudflow) are formed, which can flood and bury not only houses but also towns. The ash and lava that rains over the land and buries it is also a problem. Ash and lava is very difficult to farm on, and it only becomes fertile after a long time. Therefore, plant life would be limited, which would also affect the food chain. There might also be silting in the rivers and lakes, which stops boats from navigating through, as the depth becomes much shallower. Of course there are also some positive affects that a volcanic eruption can cause. For example, the beautiful island of Hawaii was formed because of a volcanic eruption. Not only that, after a volcanic eruption, because of the lava and ashes, the soil near the volcano will be very fertile.
