Recently, the Division of Geological Survey received funding from the Ohio Mine Subsidence Insurance Underwriters Association (OMSIUA) to investigate and compile data sources, including mine maps, to make its inventory of mine lands as complete as possible. Data gathered from abandoned underground mine (AUM) maps will aid the OMSIUA in reviewing and assessing claims filed with its Mine Subsidence Insurance Fund.

Information about the OMSIUA, including eligibility and coverage guidelines for the Mine Subsidence Insurance Fund, can be found on the OMSIUA Web site at
