While not all types of volcanic eruptions are so dramatic, they can all be terrifying. Prepare all the necessary things to bring once evacuation is needed. Volcano Learning Zone > Volcanic Hazards>Volcanic Hazard Management Volcanic Hazards fall under Geological and Geomorphological Hazards. The best way to protect yourself and your family is to follow the advice of local officials. Volcanic eruptions happen with early warnings unlike earthquakes that are sudden. Volcanoes can create tsunamis. “Active” means there’s regular activity, “dormant” means there’s been recent activity but the volcano is currently quiet, and “extinct” means it’s been so long since the last eruption … There are early warning signs before a volcano erupts so there is at least time for residents around the volcano to prepare before the actual eruption occurs. Air conditions could lead to widespread health problems. Volcano Preparedness for Businesses and Organizations.
