Listen to the Earth’s “Signal of Rescue”
During the continued heavy rainfall brought by Typhoon, mountainous soil content is saturated with a sharp decline in stability.At this time, nature tends to issue early warnings through changes in sound and shape.If you are in a mountainous or geological disaster-prone area, make sure to stay alert, pay attention to the following abnormal sounds:
- The rock broke.If you hear the sound of thunderstorms from the depths of the hillside, or if the stones collide with each other, the bright sound of friction, which is usually a signal of displacement or rupture inside the rock.
- The tree broke.Non-wind force causes the trees to suddenly tilt, break or even sound rooted, which may mean that the ground layer below is slipping.
- Unusual sound of water.The originally clear mountain stream suddenly becomes turbid, or the water stream suddenly increases, and the mud sand shock sounds, which may be a sign that the upper stream has already plunged or a mud stream.
These sounds often appear within minutes to hours before the disaster occurs, which is an extremely valuable escape window period.Once you hear such noises, do not hesitate, should immediately toward both sides of the high ground evacuation, and should never follow the valley direction running.

- Mutation of water.: Monitor nearby wells, springs or reservoirs.If the water level suddenly increases dramatically, or the water quality changes by clear, a bubble emerges, indicating that the underground rock structure has changed, and the underground water transmission channels are blocked or permeated.
- Building deformationCheck whether there are new cracks in the walls of the house, whether the door windows are suddenly difficult to switch, whether the floor is unreasonably arched.
