Some of the volcanoes of the more recent but also extinct Pleistocene South Auckland volcanic field and the currently dormant late Pleistocene and Holocene Auckland volcanic field are within 500 m (1,600 ft) of known fault lines. In the South Auckland volcanic field, the Drury Fault is in close alignment with the vents at Peach Hill, Bombay ...
Map of active faults (red #ff0000), and known (dark grey #000000 with opacity 0.5) or partially characterised inactive faults (grey #444444) in the Auckland region
The structure of the Auckland regional faults and the resulting fault blocks is complex but like the volcanic field their locations can be postulated to be related to gravitational variations and where the Stokes Magnetic Anomaly passes through this section of the North Island. [7] [8] A north south line of central volcanoes is orientated along ...
The Auckland region lies within the Australian Plate, about 400 kilometres (250 mi) west of its plate boundary with the Pacific Plate. [18] The volcanoes are located south of a geological region called the Northland Allochthon, and with the northern volcanoes located over early Miocene sedimentary deposits of the Waitematā Group of rocks and the southern volcanoes over post Miocene sediments ...
To map the subduction zone, researchers at sea performed active source seismic imaging, a technique that sends sound to the ocean floor and then processes the echoes that return. The method is ...
Satellite images reveal fault line through city near epicentre of Turkey’s deadly earthquake. Emily Atkinson. February 10, 2023 at 8:54 AM.
The Wairoa North Fault has had some notable seismic events in the past: 1835 Auckland Earthquake: A magnitude 6.5 earthquake struck Clevedon, New Zealand, with its epicenter located on the Waikopua segment of the Wairoa North Fault, and with a depth of 25 km. [5] [6] The shaking of the quake was felt strongly throughout the Auckland region, potentially causing damage to buildings and ...
