How many people can a volcano kill in one eruption?

The number of people a volcano can kill in one eruption varies widely depending on several factors, including the volcano's size, the population density of the surrounding area, and the effectiveness of emergency preparedness and response. Historical eruptions have caused fatalities ranging from a handful to tens of thousands. For instance, the eruption of Mount Tambora in 1815 is estimated to have killed around 71,000 people, while smaller eruptions might result in just a few casualties. Ultimately, the impact of an eruption on human life can be catastrophic or relatively minimal.
