When planning a visit and stay in the mountains, it is necessary to take into account the weather forecast and monitor storm warnings, respond in a timely manner to the threat of a natural disaster.
The depth of the mudflow can reach 40-50 m (especially at the gates of the channel), the flow velocity is 5-10 m/s or more (in some cases up to 15-20 m/s). If a person gets into a mudflow, a fatal outcome is inevitable, therefore compliance with safety measures is of particular importance.
Signs of mudflow hazard caused by heavy precipitation
A sharp increase in the flow rate and turbidity of water in the river.
The hum and the appearance of a cloud of mud dust in the upstream part of the riverbed.
Ground shaking in the immediate vicinity of a mudslide.
A sharp decrease in the flow rate of the mudflow caused by the collapse of the slopes and the formation of a temporary dam, the destruction of which will lead to the formation of a new wave of mudflow with a flow rate significantly exceeding the previous one.
Rules of conduct in a mudslide zone
Do not stop for rest and do not set up a tent camp near the riverbed (floodplain), dry riverbed and on the lake bridge.
To put the viewer forward so that he can see what is happening far ahead and can warn about the impending danger, as well as when taking water from the river.
In case of intensive precipitation of liquid precipitation and other signs of mudflow danger, move away from the riverbed (floodplain), dry riverbed and climb up the slope of the valley by 40-50 m.
When passing a mudflow, do not run away from it along the riverbed, climb up the slope of the valley by 40-50 m (stones can be thrown out of the mudflow).
Do not stop under steep cliffs and steep slopes (from ground shaking, in the immediate vicinity of a mudslide, landslides and rockfalls may occur).
Do not descend into the riverbed after passing the mudflow, its re-formation is possible.
After a mudslide, one should beware of sliding slopes, torn and sagging electrical wires, damaged gas mains.
