There are effects on the people as well as the environment.

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 emitted, 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.

These are both long term effects.

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 short term effects have mainly to do with the native animals-

many of them will either perish or leave the devastated area. However, they will most likely return to their habitat in less than a year.

Food chains will also be altered and left unbalanced- many insects will have grown rampant in the city, and if there are still inhabitants, many of them will succomb to Malaria and other diseases.

The long term effects are- 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.

THERE ARE ACTUALLY MANY SHORT AND LONG TERM EFFECTS OF A VOLCANO, BUT IT ALL DEPENDS OF THE SIZE, LOCATION AREA OF THE ERUPTION

Economic - destruction of infrastructure, govt has to spend lots of money on redevelopment
Social - loss of lives, loss of family members
Physical - destruction to the environment (lots of animals and plants will be killed during lava flows)

all these are short term. Over time, people will recover and life will have to go on (:

The ash ejected from the volcano that falls on the ground creates very fertile soil after and so people often return to exploit the new, richer soil this is a long term effect

Volcanic eruptions are cool,they happen when a giant lava elephant from the depths of hell squirts hot lava out of its trunk!!! Thats why volcanos erupt.
