Whenever a volcanic eruption occurs, gases and molten magma are ejected from the volcano. The gases, such as steam and sulfur dioxide, can be harmful to humans and the environment. The molten magma can flow out of the volcano and form lava flows, which can be very destructive to surrounding areas. Sometimes the eruption can also lead to the formation of volcanic ash and rocks that are ejected into the atmosphere, which can cause significant damage to buildings, crops, and infrastructure. Therefore, volcanic eruptions are potentially hazardous natural events.
