The intended seismic risk from gas extraction is negligible for gas fields N05-A, which thus fall into the lowest seismic risk category (SRA Cat. I). The independent research organisation TNO and Dutch State Supervision of Mines endorse this assessment. Due to the low negligible seismic risk and the large distance to the Wadden (islands) and mainland, no adverse effects and damages due to soil vibration from this gas production are expected.
