In genoemde overeenkomsten is vastgelegd dat de NAM eens in de vijf jaar zal rapporteren over haar bodemdalingsverwachtingen, rekening houdend met resultaten van actuele metingen en specifiek onderzoek op dit gebied. <\/SPAN><\/P>

Voor de bepaling van opgetreden bodemdaling door gaswinning worden geodetische metingen uitgevoerd. In 2018 is in Noord-Nederland een grote waterpassing uitgevoerd door Rijkswaterstaat. NAM heeft de resultaten van deze waterpassing, alsmede van satelliet radar interferometrie (InSAR) metingen, gerapporteerd als meetregisters (Referentie 5, Referentie 6). Tevens vindt er continue GNSS (Global Navigation Satellite System, GPS) monitoring plaats en zijn er sinds 2018 ook 29 Integrated Geodetic Reference Stations (IGRS) bijgeplaatst. De bodemdaling die tot 2018 in het centrum van de schotel boven het gasveld Groningen is opgetreden, bedraagt circa 37 cm. <\/SPAN><\/P>
