Quick Answer
You can increase your chances of surviving a volcanic eruption in a car by following proper safety precautions, but the likelihood of survival depends on various factors including eruption intensity, distance from the volcano, and vehicle type.
Pre-Eruption Preparation
If you live in a region prone to volcanic eruptions, have a plan in place to quickly evacuate the area. Keep your car stocked with essential supplies, including a first aid kit, flashlights, and a battery-powered radio. Store emergency food and water, such as non-perishable snacks and a minimum of one gallon of water per person per day. Ensure your car’s gas tank is at least half full, and consider keeping a portable gas container on hand.
Vehicle Safety and Eruption Response
When driving in an area experiencing a volcanic eruption, stay alert for signs of ashfall, pyroclastic flows, and lahars (volcanic mudflows). If you encounter ashfall, slow down and use low gear to avoid slipping. If you’re caught in a pyroclastic flow or lahar, pull over and turn off your engine. Remember, these flows can reach speeds of up to 100 mph and are often accompanied by loud rumbling noises. In the event of a lahar, be aware that it can quickly fill your vehicle, so prioritize finding higher ground.
Staying Informed and Evacuating Safely
Keep a NOAA Weather Radio in your car to receive timely updates on volcanic activity and evacuation instructions. If authorities order an evacuation, follow the recommended route and proceed slowly to avoid congestion. If you must drive through a lahar, do not attempt to ford the flow, as it can cause your vehicle to become trapped or swept away. Instead, seek higher ground and wait for assistance.
