Having an ongoing volcanic eruption less than 50 km from my home doesn't change anything in my daily life except that I need to be aware if there is a chance of smog made up of gases such as sulfur dioxide. So wind is the key factor.

People are rarely killed by the lava from an eruption. If you are close enough the gas can be immediately fatal.

Eruptions beneath glaciers can cause massive life threatening floods.

The most frightening immediate danger is the pyroclastic flow.

It is, to quote Wikipedia:

> a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of 100 km/h (30 m/s; 60 mph) but is capable of reaching speeds up to 700 km/h (190 m/s; 430 mph). The gases and tephra can reach temperatures of about 1,000 °C (1,800 °F).

This is what killed the people of Pompeii whose shapes have been preserved for the enjoyment of tourists.

None of these are the deadliest aspects of a volcanic eruption.

Long term pollution and a far reaching drop in temperature as well as other changes in weather, caused by gas expelled into the atmosphere, killed an estimated 20-25% of the population of Iceland in the aftermath of the 1783-1784 eruptions at Laki. It likely attributed to crop failures and famine in India, Egypt, Arabia and even Japan.
