Quick Answer
If caught in a lahar, stay calm and quickly move to higher ground or a designated evacuation area. Avoid low-lying areas and rivers, and do not attempt to cross a lahar unless you have a professional guide. Stay informed about the eruption and follow local instructions.
Staying Safe in a Lahar
If you find yourself caught in a lahar, the first thing to do is to stay calm and assess the situation. Lahars are fast-moving, turbulent mixtures of water and volcanic debris, and they can be deadly. If you’re in a vehicle, leave it immediately and move to higher ground. If you’re on foot, try to find a safe route to higher ground, avoiding low-lying areas and rivers.
Finding a Safe Location
Look for a location that is at least 10-15 feet (3-4.5 meters) above the surrounding terrain, such as a ridge or a hill. Avoid valleys and low-lying areas, as these are more likely to be flooded by the lahar. If you’re unable to find a safe location, look for a natural barrier such as a rocky outcropping or a group of trees that can protect you from the lahar.
Preparing for a Lahar
Before a lahar occurs, it’s essential to be prepared. Familiarize yourself with the local terrain and identify potential lahar paths. Know the evacuation routes and emergency shelters in your area. Keep a emergency kit with you at all times, including a first aid kit, a radio, and a flashlight. Stay informed about the volcano’s activity and follow local instructions, such as evacuation orders or shelter-in-place orders.
