Quick Answer
When camping near active volcanoes, consider safe locations at least 10 miles away from the volcano's base, where the terrain allows for easy evacuation in case of an eruption. Look for high ground and avoid valleys and low-lying areas that could be affected by pyroclastic flows or lahars. Choose areas with minimal ash fall risk.
Volcanic Eruption Hazards
When camping near active volcanoes, be aware of the potential hazards associated with eruptions. Pyroclastic flows are extremely hot, fast-moving clouds of ash, gas, and rock that can reach temperatures of over 800°F (427°C). Lahars are mudflows caused by ash and debris mixing with water, which can be just as deadly. Stay informed about the volcano’s activity and be prepared to evacuate at a moment’s notice.
Safe Camping Locations
Look for areas with a clear escape route, such as a ridgeline or a slope that allows for easy evacuation. Avoid areas with steep cliffs or narrow valleys that could trap you in case of an eruption. Consider camping near the rim of a caldera or on a high plateau, where the terrain allows for a safe escape route. In Hawaii, consider camping areas like Mauna Kea, Haleakala, or Mauna Loa’s western flank, which are relatively safe from pyroclastic flows and lahars. On Mount St. Helens, consider camping areas like the Mount St. Helens National Monument’s North Fork Toutle River valley or the Spirit Lake area, which are safer than the mountain’s flanks.
