Detailed explanation-1: -Cracks around door and window frames. An increasing number of exposed tree roots on your property. Cracks in your foundation, walls, or swimming pool. Sagging fence posts, utility poles or trees, or loosening of the soil around them.
Detailed explanation-2: -Water breaks through the ground surface in new locations. Fences, retaining walls, utility poles, or trees tilt or move. A faint rumbling sound that increases in volume is noticeable as the landslide nears. Unusual sounds, such as trees cracking or boulders knocking together, might indicate moving debris.
Detailed explanation-3: -So how do scientists like us detect a sinkhole before they appear at the surface? The geology of the rocks beneath you is a clue to the possibility of sinkholes. Limestone is prone to dissolution by groundwater which can, over time, create enormous networks of underground caves known as karst.
Detailed explanation-4: -New cracks or unusual bulges in the ground, street or sidewalks. Soil moving away from foundations, or the tilting or cracking of concrete floors and foundations. Sunken or down-dropped road beds. Rapid increase in creek water levels, possibly accompanied by increased soil content.
