Recent evacuations in Godstone, Surrey have raised alarms due to two large sinkholes that pose a risk of triggering a gas explosion. These sinkholes occur when underlying rock collapses, often due to factors like acidic rainfall or erosion. They are typically deep and can be triggered by events such as heavy rain or construction activities. Areas like Godstone, which are sitting on weakly cemented sands, are particularly vulnerable. Geologists note that such incidents can be exacerbated by sudden changes in the region's hydrogeology.
Residents have been evacuated in Godstone, Surrey due to fears that two large sinkholes might trigger a gas explosion, highlighting their potential danger in urban areas.
Sinkholes form when the ground collapses due to various factors including dissolution of soluble rock, heavy rainfall, and human activities, posing risks especially in vulnerable areas.
