What fault lines exist around Kaikoura?

What fault lines exist around Kaikoura?

The magnitude 7.8 Kaikoura earthquake in 2016 was a complex event, involving movement on at least seven faults – The Humps faults and the Hundalee, Hope, Jordan Thrust, Papatea, Kekerengu and Needles faults.

What tectonic plates caused the Kaikoura earthquake?

The complex earthquake rupture occurred along multiple faults within a triple junction area between the Pacific, Australia, and Tonga–Kermadec plates, located near Kaikoura.

What fault caused the Kaikoura earthquake?

The Papatea Fault has proven interesting to Kiwi and international scientists studying it. When the magnitude-7.8 earthquake struck Kaikōura in 2016, it massively altered the landscape and lives of the locals.

What does it mean when a fault ruptures?

Surface rupture is an offset of the ground surface when fault rupture extends to the Earth’s surface. Any structure built across the fault is at risk of being torn apart as the two sides of the fault slip past each other. Structures that span a surface fault are likely to suffer great damage surface ruptures.

Does Christchurch sit on a fault line?

The Christchurch Fault is an active seismic fault running under the city of Christchurch in the middle of New Zealand’s South Island. The Christchurch fault is believed to have been responsible for a series of earthquakes that rocked the city on Boxing Day of 2010.

Is New Zealand on a fault line?

There are major fault lines running the length of New Zealand. In the South Island, the Marlborough Fault System is another series of major parallel faults. These join together further south to form the Alpine Fault which carries most of the total plate boundary strain.

What are the effects of ground rupture?

Ground rupture and liquefaction can easily rupture natural gas mains and water mains, both contributing to the ignition of fires and hindering the efforts to control them.

Why do some fault called as inactive fault?

Inactive faults are structures that we can identify, but which do no have earthquakes. As you can imagine, because of the complexity of earthquake activity, judging a fault to be inactive can be tricky, but often we can measure the last time substantial offset occurred across a fault.

How big is the Kekerengu Fault in Kaikoura?

The Kekerengu Fault is one of several to have ruptured during the Kaikoura earthquake on the South Island. Scientists estimate the surface rupture to be about 30km (19 miles) long.

Where are the fault lines in New Zealand?

The faults in North Canterbury and Marlborough represent the shearing and breaking of the earth’s crust that happens when tectonic plates change from sliding past each other to colliding head-on.

Where are the Jordan Thrust and Hope Faults?

The Kelly Fault forms a major fork of the Hope Fault from just west of Harper Pass; it forks again to the west into the Newton and Hura faults just before connecting to the Alpine Fault. The Jordan Thrust is a reverse fault that connects the southern end of the Kekerengu Fault to the Seaward Segment of the Hope Fault.

Where was the epicenter of the New Zealand earthquake?

Epic drone footage captures giant cracks left by New Zealand earthquake (VIDEOS) Following the 7.8-magnitude earthquake which struck New Zealand’s South Island last week, scientists sent a drone to examine the damage left in its wake along the Kekerengu and Papatea fault line ruptures.
