New Zealand's GeoNet has revised their initial magnitude of the November 13, 2016 Kaikoura earthquake from M7.5 to M7.8. Our landslide and paleoseismology teams quickly took to the skies to spot landslides in the Kaikouras and Southern Alps. Ruptures occurred on multiple faults and the earthquake has been described as the "most complex earthquake ever studied". The effects can be seen all over Kaikoura, with some areas rising a metre above the ground, and stretching several metres down the coast. The 2016 Kaikoura earthquake plus two years of creeping movement has left the North and South Islands 14 inches closer than they were before. It straddled two distinct active fault domains, rupturing faults in both the North Canterbury Fault zone and the Marlborough Fault system. The Kaikoura earthquake rupture began in North Canterbury and propagated northward for more than 170 km (106 miles) along both well-known and previously unknown faults. After the January update, more geodetic data became available which enabled LINZ to improve the modelling of this earthquake. The 2016 Kaikoura earthquake resulted in significant land movements across much of New Zealand.
The Kaikoura earthquake struck just after midnight on November 14, devastating Kaikoura and causing major problems in Wellington. Previously unknown faultlines have been discovered by geologists surveying which fault lines ruptured in Monday's devastating Kaikoura earthquake. The 2016 Kaikoura earthquake was a magnitude 7.8 (M w) earthquake in the South Island of New Zealand that occurred two minutes after midnight on 14 November 2016 NZDT (11:02 on 13 November UTC). GPS allowed rapid detection of land movements due to M7.8 earthquake Within a couple of hours of the M7.8 earthquake, GeoNet was able to use the GPS data to estimate the initial displacements of… Apply the adjustment using ogr2ogr ; January 2018 NZGD2000 coordinate update ; Land movement maps ; Order in Council under the Hurunui/Kaikōura Earthquakes Recovery Act 2016 ; Post-earthquake co-ordinates ; Surveys for post-earthquake geodetic control But with the M7.8 Kaikoura Earthquake, landslides and land deformation have been at the forefront of risk to communities living in North Canterbury and Marlborough.
Back to Landing page Kaikoura earthquakes; Kaikoura earthquake coordinate update . Geonet have been busy measuring how much the ground moved in this week's earthquakes (it is still moving in some parts). Satellite photographs captured by NASA's Earth Observatory reveal new land along the Kaikoura coastline pushed up from under the sea by the 7.8 magnitude earthquake that hit New Zealand. Co-seismic movement occurs when earthquake waves arrive all at the same time, releasing great amounts of energy along a fault line. The movement is … The majority of this movement was accounted for in a January 2018 update to Landonline and the Geodetic Database. 12.11am EST 00:11 'One of the most complex earthquakes ever recorded on land' 11.54pm EST 23:54 600 people evacuated from Kaikoura … The agency added that early indications show this was one of the most complex earthquakes ever recorded on land.
