When are Volcanoes considered as threats to life and property?

Volcanoes are considered threats to life and property when they exhibit signs of potential eruptions, such as increased seismic activity, gas emissions, and ground deformation. The actual eruption can pose risks through lava flows, pyroclastic flows, ashfall, and volcanic gases, all of which can endanger human lives and damage infrastructure. Proximity to populated areas, inadequate preparedness, and lack of effective monitoring further elevate these risks. Therefore, areas near active volcanoes are often closely monitored to mitigate potential hazards.
