Quick Answer
Landslide warning signs include visible changes in the terrain, such as new cracks in the ground, rockfalls, and increased vegetation growth. Changes in water flow patterns, such as sudden increases in creek or river flow, can also indicate a potential landslide. Additionally, unusual sounds like rumbling or roaring can signal a landslide.
Recognizing Landslide Warning Signs
When inspecting an area prone to landslides, look for visible evidence of recent rockfalls, cracks in the ground, and new growth of vegetation. Increased vegetation growth can be a sign of increased moisture in the soil, which can lead to soil instability. Check for new or widening cracks in the ground, as these can be indicative of ground movement.
Identifying Water Flow Patterns
Changes in water flow patterns can indicate a potential landslide. Pay attention to sudden increases in creek or river flow, as these can be a sign of increased rainfall or snowmelt that can trigger a landslide. Also, observe if the water flow appears to be changing course or has sudden drops in elevation.
Preparing for a Landslide
If you suspect a landslide is imminent, immediately seek higher ground or an area that is far away from the potential landslide site. Escape direction should be uphill and away from the slope where the landslide is occurring. Avoid attempting to cross a creek or river flowing rapidly, as the increased flow can signal a potential debris flow, which can be deadly. Know the escape routes and plan ahead with emergency supplies in case of a landslide.
Buried Rescue Techniques
If you are buried under debris from a landslide, try to stay calm and conserve energy. If you have a whistle or any other noise-making device, use it to signal for help. If you are trapped, try to move your arms and legs to create space and make it easier for rescue teams to locate you. Remember, rescue teams will likely use specialized equipment to locate and extract you, so try to remain still and avoid causing further damage to the debris.
Debris Flow and Landslide Response
If you are caught in a debris flow, do not attempt to cross the flow or try to swim against it. Instead, lie flat on the surface and cover your head and neck with your arms. Debris flows can be incredibly powerful and can sweep away even the strongest swimmers. Stay calm, and wait for the flow to pass, then seek higher ground and safety.
