New Zealand - Great Alpine Fault Earthquake Talks

Last days we have some stronger seizmic activity in New Zealand, so I will post some info about situation there ..

Think soon in time ahead probably in this years there will come some stronger earthquake of M 7.4 + and much possibility for "The Big One" of M 8.0 + on fault in north-west side of south island probably around Milford Sound area ..

Last EQ of M 8.0+ was in 1717 AD, that's before 296 years ..

The Alpine fault connects two "subduction" margins where the ocean floor descends into the Earth's mantle. At this point the surfaces of the two plates making up the South Islands alpine fault meet.

The Pacific Plate on the easterly area of New Zealand is moving westwards and the Australian Plate, on the western side of New Zealand moves eastwards. They move at a relative rate of about 45mm per year.

As these two plates move against each other enormous pressure builds up which must eventually be released through earth movement. The result is a major earthquake along the Alpine fault. The pressure has been continually building for about 280 years since it was last released by a large earthquake in 1717 AD.

The next earthquake centred on the Alpine Fault should begin in South Westland and will probably have a magnitude of 8+.

The historical patterns of earthquakes and current research on the alpine fault indicate that it is likely to rupture very soon.

8000-year quake record improves understanding of Alpine Fault - 28/06/2012

28/06/2012 12:25 pm

A geological study of the southern section of the Alpine Fault spanning the past 8000 years has given scientists an improved understanding of the behaviour of this major plate boundary fault.

This fault has ruptured four times in the past 900 years, each time producing an earthquake of about magnitude 8. Approximate rupture dates are 1717AD, 1620 AD, 1450 AD, and 1100 AD. Recent research (published in 2012) by GNS Science has extended our knowledge of the Alpine fault earthquake record back through the past 8000 years

The Alpine Fault goes to relatively sparsely populated areas with no tall buildings. Since it's a strike-slip fault, the danger of tsunami is probably very small.

The greater danger comes from the earthquakes it make awakening the Rotorua and Taupo volcanic zones.

You quoting this professor or just typing your own stuff? Reason I ask is that Milford Sound is not in the Northwest of the South Island, it is in the far Southwest.

Probably South island around Milford Sound area to east ..

Last 48 hours of earthquake activity for Wellington, New Zealand

Wellington earthquake: Terrifying tremors not over

www.nzherald.co.nz...

Don't forget the Hope Fault, and the Esk Fault has been reasonably active lately.
Maybe there will be a large earthquake on the Alpine Fault around the Gaunt Creek area, or it could occur further north.
There is a whole lot of ongoing research at the moment and while South Westland is one of the potential areas for rupture, the fault is long....it could be at Inchbonnie, or Springs Junction, or near Murchison.
The best thing is to be prepared with a survival kit including transistor radio, candles, matches, water, food, dynamo flashlight, first aid kit etc etc.
One of the biggest issues post quake in Christchurch was power supply, so being able to make a rudimentary fridge (terra cotta pots, sand) is also a good option.

Yes of course that all sensitive areas are very dangerous for strong earthquake In New Zealand, here on this maps are most dangerous areas ..

Christchurch also like I say in post above new fault creating there ..

I wouldn't call it a new fault, since it has ruptured in the past (c. 16000 years ago). I would be more inclined to call it a previously unknown fault. Yes, it is semantics, but "new" to me implies that it has only just formed, which it hasn't. The Greendale Fault is related, however, to the relative plate motion and the southward migration of the plate boundary and all the associated twisting and buckling that occurs (see also the Waipara anticline as a manifestation of these forces), eventually it is expected that some stepover will occur and the Hope Fault will become the northward extension of the Alpine Fault.

Yes but It still forming ..

How I see things it will be more and more activity there and strong rapture in future at Christchurch area ..
