Today is the 8th anniversary of the 2011 Christchurch Earthquake. Ken Gledhill was the Director of GeoNet at the time and shares some memories from the time and reflects on how GeoNet has been shaped by the quake.
GeoNet has registered 39 earthquakes clustered in an area of the Hauraki Gulf to the east of Whangarei since December 26, 2018. The largest of these quakes was a M4.1 on February 10, 2019.
Landslides are one of the geohazards that GeoNet monitors and last week our landslide team responded to a cliff collapse event at Cape Kidnappers that injured two people.
After last night's quake we thought we'd answer some of your questions about what happened and give an explanation for the multiple reported quakes.
GNS Science has opened the National Geohazards Monitoring Centre – powered by GeoNet.
The water level in the crater lake at Whakaari/White Island has risen around 10 metres so far in 2018. If it continues to rise at the same rate it will start to overflow around mid-2019.
In the days following the Kaikōura quake our field technicians installed over 20 new instruments in the upper South Island to help us better locate the many aftershocks and see how the land was moving. What have we done since then?
It was New Zealand’s most complex earthquake ever recorded, with more than 20 faults rupturing. Our seismologists have prepared aftershock forecasts for the region since the quake. So, two years on, how are they stacking up?
It was a scary time, and many New Zealanders rushed to update their emergency preparedness plans. But how can we make sure people stay prepared?
Hazards from landslides triggered by the M7.8 Kaikōura quake will continue to pose a threat for many years as loose sediment remains in the hills and valleys. Two years on, our scientists are still studying the effects of this huge quake.
