A volcanic eruption can be an awesome and destructive event. Here are some tips on how to avoid danger and what to do if you're caught near an eruption.
• Stay away from active volcanoes.
• If you live near an active volcano, keep goggles and a mask in an emergency kit, along with a flashlight and a working, battery-operated radio.
• Know your evacuation route. Keep gas in your car.
If a Volcano Erupts in Your Area
• Evacuate only as recommended by authorities to stay clear of lava, mud flows, and flying rocks and debris.
• Avoid river areas and low-lying regions.
• Before you leave the house, change into long-sleeved shirts and long pants and use goggles or eyeglasses, not contacts. Wear an emergency mask or hold a damp cloth over your face.
• If you are not evacuating, close windows and doors and block chimneys and other vents, to prevent ash from coming into the house.
• Be aware that ash may put excess weight on your roof and need to be swept away. Wear protection during cleanups.
• Ash can damage engines and metal parts, so avoid driving. If you must drive, stay below 35 miles (56 kilometers) an hour.
