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 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.
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.

∙ 13y agojust some ideas-
poverty throughout country's (especially 3rd world country's, EG Haiti, India)
poor hygiene and sanitation (sewers affected very badly)
poor hospital care- doctors dead ( and nurses etc.) drugs not available roads to bad.
Not enough food to go around because roads can be blocked by volcanic ash/lava.
Orphans- parents killed- they don't know where to go ?
Bodies- the smell is terrible !
Hope that helps :)
Also to get extra marks (if this is for school) mention pyroclastic flow and the gases it produces (also reduces visibility)
:)

What are some recent eruptions of the mauna loa volcano?
last eruption was in 1984
What materials does the composite volcano have after erupting?
Eruptions from composite volcanoes vary. Some eruptions will produce ash and pumice, some produce volcanic bombs, while still others produce lava flows.
How many years between every volcano eruption from 1 volcano?
It varies widely. Some volcanoes will erupt every few years or even every few months while others can go hundreds of years without an eruption. Even for one volcano activity is not regular. Major eruptions are often preceded and followed by a series of small eruptions.
Which volcano that has erupted in recent times?
Well Hawaii is made by a volcano a long time ago but probably some new Islands are being made from the underground volcanos right now there growing at the rate of your fingernails grow
How strong is a volcano?
the type of magma and the amount of dissolved gas also viscosity
What are some effects of volcano eruptions?
loss of habitat aswell as volcanic ash blocking sunlight from the surrounding land. collis.
Why are some volcanic eruptions gentle and others violent and why do scientist make a distinction?
Because it all depends on what type of volcano it is, if it is a shield volcano low and flat it's eruptions will be gentle. But if it is a cone volcano tall and steep it's eruptions will be very violent.

What are some triggers for volcanic eruptions?
In an inactive volcano, magma that is traveling towards the surface of the volcano can trigger eruption. Science is also indicating that earthquakes can be a causative factor in the eruption of a volcano.
What do humans have on volcano?
A volcano eruption is one of the most impressive events in the planet and the effects of volcanoes and their eruptions could be felt as far away as a different continent. The type of effects of volcanoes depends on the size of the eruption. Some volcanoes could be erupting and not cause much damage even to people nearby while others are so massive that should they erupt they could trigger a world sized catastrophe. So what type of disturbances would you see if there were a massive eruption today? To answer that question we need to be clear about the type of volcano that we are talking about. Volcano eruptions are measured in what is called VEI or Volcano Eruption Index which goes to a most powerful eruption of a VEI8.

Short term effects of a large eruption?
The most important factor in determining the effects of a volcano eruption on the people, wildlife, and vegetation near the volcano is the type of eruption (which depends on the type of volcano). There are two basic kinds of eruptions and any volcano can erupt as some combination of these. The first type of eruption consists mostly of molten rock running over the surface of the Earth like a thick liquid. This kind of volcano often comes from the ocean floor and some of the most familiar examples are lava flows that occur in Hawaii. In terms of effects on people and animals, these lava flows usually move slowly enough that animals can get out of the way in time. But they are very hot and bury any vegetation (or houses!) in their path and often can start fires that are dangerous.

the type of magma and the amount of dissolved gas also viscosity
What are some benefits that a volcano or volcanic region might offer?
Volcanoes build additional land, as in the Hawaiian islands. Areas where eruptions took place several generations ago are often very fertile. Fine ash can also aid water retention of the soil. However, if the eruptions are current or very recent, the effects of ash on plants and animals is detrimental to their health and survival.
What kind of eruption form composite cone volcano?
Composite volcanoes are highly variable in what they erupt. Most often, eruptions will release clouds of ash, pumice, and rock fragments. In some cases they fountain or extrude lava.
