Quick Answer
In case of a lava flow, evacuate towards low-lying areas, and move downhill to avoid inhaling toxic fumes. If possible, use a westerly route to avoid direct exposure to heat. Stay at least a mile away from the lava flow.
Understanding Lava Flow Patterns
When evacuating from a lava flow, it’s essential to understand the flow’s direction and speed. Typically, lava flows downhill, but the direction and speed can be influenced by terrain, wind, and other factors. Familiarize yourself with the local topography to determine the safest evacuation routes.
Route Selection and Precautions
For evacuation, choose routes that follow water courses, such as rivers or streams. These often provide a natural barrier against lava flows. Avoid walking through dry riverbeds, as they can become channels for lava. When possible, move uphill away from the lava flow, but be aware that this can make you more susceptible to toxic gas inhalation. For every 10 feet of downhill distance, maintain a 1-2 minute interval to avoid being caught by the rapidly advancing lava.
Essential Evacuation Techniques
To minimize exposure and risk of injury, use the “lava wall” technique: move as close to the lava as possible without getting caught, then immediately turn and move in a perpendicular direction. This allows you to maintain a safe distance while also avoiding the toxic gas-filled air above the flow. When unable to see the lava flow, rely on the sounds of rumbling or crackling to guide your evacuation.
