Things you can do to stay safe from a Volcanic eruption
1) Listen for emergency information and evacuate when told so by authorities. Evacuate early and when driving or going to your destination avoid falling ash and the downstream of the eruption. Wear a face mask and long sleeves

3) Listen to local radios to follow
instructions. Try to stay indoor to avoid falling ash. When going outside your home clean up the gutters and clear your roof of heavy ash to avoid the roof from collapsing. Also wear a mask when going outside.
