Inspire ST NZ, Hazard Statements Subrosion

The topic “Earth and lowering areas” is intended to point out geogeneous natural hazards caused by subrosion/carasing without evaluating them in detail. The focus is on informing users where rocks are common in the geological subsurface, which are subject to natural subrosion processes and at the same time can have an impact on the Earth’s surface (potential hazard areas). It was assumed to be close to the surface of the affected subrodable rocks down to a depth of about 100 metres of them, without making a distinction in carbonate, sulphate or chloride karst. At the same time, the dissemination of events already occurred was taken into account. The previously occurring and recorded subrosion events (earths, reductions, cleft intrusions) are represented as single objects. They are buffered with a 100 m grid for data protection reasons. Here, both recent and fossil events are included without distinction.
