Site Identification of the GNSS Monument Site Name : Wellington Airport Four Character ID : WGTN Monument Inscription : none IERS DOMES Number : 50208M003 CDP Number : none Monument Description : PILLAR Height of the Monument : 0.69 m Monument Foundation : CONCRETE BLOCK Foundation Depth : 0.3 m Marker Description : STAINLESS STEEL PLATE Date Installed : 1996-05-17T00:00Z Geologic Characteristic : BEDROCK Bedrock Type : GREYWACKE Bedrock Condition : GOOD Fracture Spacing : unknown Fault zones nearby : YES Distance/activity : The site is located at the Pacific-Australian : plate boundary and several major active faults : are present in the area (the closer being the : Wellington Fault). Additional Information : Monument construction: A hole was dug through a : thin layer of soil and into weathered : greywacke outcrop. A reinforced concrete pad : was built on the greywack surface, with a 70 : cm high reinforced concrete pillar above the : pad. The pad was not attached to the : underlying rock except by gravity and the : binding of the concrete to the rock. This : monument is therefore likely to be less stable : in the event of an earthquake than later : monument installations in New Zealand. In the : absence of strong ground shaking there is no : concern about monument stability. : Marker description: 5/8 inch thread in centre : of 150 mm diameter stainless steel plate set : horizontally in top of approx. 400 mm diameter : concrete pillar. 2.
