When Krakatoa erupted back in the 1880's, the entire world had spectacular sunsets for months. That much ash got pumped into the air. That volume of volcanic ash almost certainly caused global cooling as less sunlight got to the ground.
The Hawaiian Islands are the result of several millennia of major volcanic eruptions.
The volcano Stromboli in Italy has destructive eruptions every few centuries or so, but people continue to live on its slopes -- probably because the volcanic soil is incredibly fertile.
Every volcanic eruption brings minerals from beneath the Earth's crust to the surface (or close to it, at least). Every diamond you've ever seen got up here that way.

It depends on what type of eruption. Some eruptions send out steady streams of lava. The speed of the lava is usually not very fast or wide spread so people and animals can get out of the way easily. Land in the path of the lava will be covered with hard volcanic rock which won't support plants for many years. Plants and structures will be destroyed. Near a coastline the lava may flow out to sea and create new land. Kilauea on Hawaii and Mt. Etna in Sicily erupt like this.
A explosive eruption sends large quantities of volcanic ash into the air. It can quickly blanket large areas in all directions causing a large loss of life. The ash can bury whole cities. A really large eruption of this type can send ash and gasses into the upper atmosphere where they can cause lower temperatures world wide for up to several years. Mt. St. Helens in Oregon and Mt. Vesuvius in Italy erupted in this way.
Major eruptions are often accompanied by earthquakes which can damage buildings and injure people and animals on their own.

A major volcanic eruption it might trigger other volcanoes, cause earthquakes, or create a new landmass.

Hi. Local effects would be ash deposits, possibly of significant depth. Globally cooler temperatures due to dust reflecting light before it reaches the surface.

Burn things and kill people.. but there are benefits to eruptions as well..Many islands are made of lava rock and would not be there otherwise.

Darkness for days. Little visibility. Sneezing and coughing.
Destruction of buildings, land, rivers and lakes.
