Active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.
<h3>What are active volcanoes?</h3>
Active volcanoes are geological formations that have regular cycles of eruptions, releasing liquid magma to the Earth's surface.
These eruptions are composed of rocks (or ash weathers) that generate fertile soils, but also may affect the respiratory airways.
