Townsend Fault 5.2

2011-06-05T15:52:00.002+12:00

On 29th April 2011 UTC (Apr 30th 2011 at 7:08 am NZST) a Moderate quake hit the eastern foothills of the Southern Alps north of Oxford, Canterbury.
The quake was felt throughout the central Canterbury region from Hanmer Springs in the north to Timaru in the south, as well as on the West Coast from Westport down to Okarito, and several reports from as far afield as Dunedin and Nelson.
The highest Intensity was MM6, Slightly Damaging, in Fernside, Oxford, Riccarton and Springfield.

After the recent large Canterbury earthquakes of Sept 3rd 2010 at Darfield (7.1) and Feb 22nd 2011 (6.3) one would tend to think this quake at Lees Valley is just another aftershock, but this was in fact a quake on another Faultline altogether, the Townsend Fault.
There is a possibility that the Darfield 7.1 and the Lyttelton 6.3 put stress on the Townsend Fault and caused this failure on April 29th.

Here I have gone back and checked the data for the fault and surrounding area, north and south of Oxford Hill to see what the history of the Fault is.
The Search area is Lat -43.135245 to Lat -43.236639 and Long 171.956520 to 172.171753

The fault to the south of Oxford Hill is called the Coopers Creek Fault.
Both Faults join up to the Glen Tui Fault to the east, the Lees Valley Fault to the northeast and the Porters Pass Fault to the west.

In the 5 days since the 5.178ML quake there have been 8 aftershocks in the immediate area of Black Hill and the Townsend River.

Onepu Fault Swarm Feb 17 2011

2011-02-21T07:01:00.004+13:00

On the 17th February 2011 UTC ( 17-18th NZDT) a small swarm of micro earthquakes occured in the Kawerau Geothermal Feild NW of the Onepu rhyodacite Domes, over a period of 15 hours. The trend of the series of quakes was SW to NE which follows the Onepu Fault. The most intense consentration of quakes was from 2:20 am to 2:40 am NZDT with no quake more than 7 minutes apart, 7 in all.
Of the 17 events in the confined Swarm, 5 were reported as felt by the public
Two of the quakes listed below are outside the main area of the swarm, but may be related due to the volcanic nature of the entire Bay of Plenty region. Note: The Lake Aniwhenua 4.378 quake wll not show on the map without zooming out

Mt. Tihia/Tokaanu Introduction

2010-11-27T17:05:00.000+13:00

The parameters of Latitude and Longitude that have been used in this research/study have been set by the recent earthquake swarm of events in the area starting June 26th. 2009. These events followed on from activity during the previous month to the south at Lakes Rotoaira & Lake Rotopounamu.
They are Northern Latitude –38.945 (-38° 56' 42" S), Southern Latitude -39.015 (-39° 0' 54"), Western Latitude 175.66 (175° 39' 35.9994" E), Eastern Latitude 175.79 (175° 47' 23.9994" E).
The maps below show the search areas as a darker shade.

Geology
The Taupo Volcanic Zone lies above the sub-ducting Pacific Plate and is crossed by NE-NW trending faults of the Taupo Graben
Andesite magma occasionally wells up through some of these faults, resulting in chains of volcanic features parallel to the boundry plate.
An exception to the general trend are three old cones north of Lake Rotoaira; Mt. Pihanga, Mt. Tihia and Mt Kakaramea.
These 3 volcanoes relate to a pre-Taupo Graben plate boundry and associated faults which lay at right angles .( NW-SE)to the current ones (NE-SW)
The north-westerly trending Kakaramea-Tihia Massif and Pihanga form a chain of volcanoes which last erupted more than 20,000 years ago, but from which large mudflows have recurred up to as recently as 1910 A.D.

Of the other cones or domes in the area geologigal studies have shown that Papanetu Tephra was erupted from the site of Kuharua Dome c. 9,785 years ago towards the end of dome formation. Manganamu Dome is younger than 1819 years old.

Tokaanu–Waihi geothermal field is situated near the southern end of the Taupo Volcanic Zone. Neutral chloride thermal waters discharge at Tokaanu and Waihi in the north of the field on flat land between the andesite volcanoes Tihia and Kakaramea and the shore of Lake Taupo, while steam-heated thermal features occur at Hipaua on the northern flanks of Kakaramea. Electrical resistivity surveys have shown that Tokaanu, Waihi and Hipaua all lie within a continuous region of low apparent resistivity (5–20 Ωm) and are thus part of the same geothermal system. Interpretation of the resistivity and other data suggests that the Tokaanu–Waihi thermal waters rise nearly vertically from a source deep beneath the elevated southwestern part of the field to the water table. These waters then flow north to discharge at the surface near Lake Taupo. Neighbouring geothermal systems, which occur at Tongariro about 18 km south of Tokaanu–Waihi, and at Motuoapa about 10 km to the northeast, are separated from the Tokaanu–Waihi field by high resistivity ground. This suggests that the thermal fluids discharging at the three fields do not have a common source, as has been suggested previously.
The steaming ground area Hipaua is the 3rd largest of its kind in the TVZ and covers approx.1km2 of steep ground along the Waihi Fault.

Event Recording
Early earthquake activity in the southern Taupo Volcanic Zone was recorded with the national seismic network, then more so from 1966 onwards when a seismometer near Mt Ruapehu was incorporated in the network. The detectable number of swarms increased significantly when, in 1985, a sub-network around Lake Taupo was installed - the Taupo Network, which recorded events with a magnitude less than 2 ML. Prior to 1985, only events with ML greater than 3.0 had been recorded.
The Taupo Seismic Network was a network of six telemetred seismographs that operated around Lake Taupo between 1985 September and 1991 July.
The stations were;
KETZ at Ketetahi
RATZ at Rangitukua
HITZ at Hingarae
HATZ at Hinemaiaia
TUTZ at Tuhingamata
HUTZ at Hika Falls
They are now integrated into the WELT Network run by the Institute of Geological and Nuclear Sciences.

Okataina Volcanic Center July 24-31 2010

2010-08-03T07:03:00.004+12:00

A swarm of earthquakes at Okataina Volcanic Center started on the 24th July 2010. The trend of the swarm is in a south west to north east direction between Te Horoa Dome in the south and Rotokohu Dome in the north and generally confined between Lake Okataina in the west and the Tarawera River in the east.
The swarm has seen two sets of multiple events, the first on 24th July of 29 quakes, with the main cluster located between Tuahu and Makatiti Domes, and other individual events running in a line SW to NE.

A moderate 5.318ML earthquake occurred on Saturday, June 12 2010 at 2:20 am NZST 100km to the south and was reported widely felt throughout the lower North Island and upper South Island. It is unclear if this larger event is related to the Cape Egmont swarm as the faults south of the Cape Egmont Fault Zone in the South Taranaki Bight have yet to be determined west of the Manaia Fault.

July 15th 2009 Fiordland 7.3ML

2009-10-04T05:03:00.007+13:00

This Fiordland earthquake caused power outages in several parts of the South Island and only minor damage. Reported damage includes a broken water main at Winton, cracks in exterior walls of buildings at Invercargill and items falling from shelves throughout the Southland region. Several small landslides were also reported.
Measurements indicate a geographic shift to the west towards Australia of 30.5 cm of the southern tip of the South Island. Felt (VI) at Te Anau and Tuatapere; (V) at Arrowtown, Edendale, Lumsden and Winton; (IV) at Bluff, Gore, Invercargill,Outram, Queenstown and Wanaka. It was felt throughout the South Island, and also the lower North Island and as far away as eastern Australia.
A tsunami with wave heights (peak-to-trough) was recorded at the following stations: 100cm at Jackson Bay; 25cm at Charleston; 12cm at Dog Island, New Zealand; 14cm at Port Kembla, Australia and 6cm at Spring Bay, Australia.

The thrust earthquake occurred near the southern tip of South Island in a region known as Fiordland, in a complex area of transition in plate boundary structure from Puysegur subduction to Alpine fault strike-slip motion. The preliminary location, depth, and estimate of fault orientation of this event are consistent with the earthquake having resulted from slip on the subduction thrust interface between the Pacific and Australian plates. The deformed Australian plate beneath Fiordland is highly active both along its’ interface with the Pacific plate and internal to the subducted Australian plate. Over the past two decades, several large earthquakes have occurred in Fiordland, predominantly in a cluster to the northeast of today’s earthquake. Though the faulting mechanisms of those events are similar to the 15th July earthquake, their slip vectors are rotated clockwise with respect to plate motions, and thus may not represent exactly the same style of faulting.
The most recent of these previous large events occurred on August 21st 2003 when a magnitude 7.2 Mw earthquake approximately 100 km to the northwest caused minor damage in Otago and Southland, and numerous landslides across the Fiordland region. A magnitude 6.7 event on August 10, 1993 caused power outages in the Te Anau area and was felt throughout South Island and as far away as Sydney, Australia. A magnitude 6.1 earthquake struck on May 31, 1989 and was felt strongly in the southwestern part of South Island and a magnitude 6.7 quake struck on 3rd June 1988 near Charles Sound.

2009 June -July Mt. Tihia Tokaanu swarm

2009-07-07T17:25:00.003+12:00

The Mt. Tihia/Tokaanu Swarm of June/July 2009 was basically broken into 2 separate sequences north and south of the summit of Mt. Tihia.
The first swarm started on 11th June with 2 micro quakes and another on the 12th, but on the 14th the area really started to show evidence of activity in the southern flanks of the mountain. There were no quakes in the area on the 21st June, so I took the last quake on the 20th June at 14:18:23.8 as the break point before the 2nd sequence started on the 22nd more towards the northern base of the volcano and Tokaanu.
The 2nd sequence ran through to July 10th when activity petered off.
There were no quakes on the 4th, 6th and 7th July, but it would be hard to deny that this is one big swarm, broken down into 3 sequences or bunches, even with those gaps.

If you take in the earlier events of late May further south near Lake Rotoaira, from May 30th to June 8th at the northern end of Lake Rotoaira, which had 105 events and add them to the 2 other sequences ( based on date and location) that brings the total to 849 events between May 30th and 10th July in the area.
The map below shows all the events May 30th and 10th July using a combination of breaks in the dates (when there were no quakes) and also as the majority of the events moved as a group, to separate it down to 3 main bunches or sequences.

Data for the first swarm can be viewed in detail on the page. Rotoaira/Rotopounamu swarm

The second part of the overall swarm (or the first part of the Mt.Tihia /Tokaanu part) started on 11th June and ran through to 20th June, the map below shows all the events of this period.
First map shows location and magnitude and the second map breaks the swarm down on a daily basis ( magnitudes are not shown)

The following map and data on a swarm in 1987 is taken from a paper presented by Steven Sherburn and published in the New Zealand Journal of Geology and Geophysics 1993 Vol 36:61-68, entitled “The 1987 January Tokaanu earthquake sequence, New Zealand”.

"The 1987 Tokaanu earthquake sequence started at 1987 Jan 27 1923 UTC, and continued until Jan 28 0215 UTC, a duration of almost 7 hours. The largest earthquake in the sequence was 3.6ML Sixty-four earthquakes were recorded on the nearest seismograph during the sequence, and 26 of these were located (shown on maps below). The epicentres were centred 1-2 km northwest of the Tokaanu Power Station, at the northeastern foot of Kakaramea, and about 1-2 km east of the Waihi Fault "

The digital data used in this study come from the Taupo Seismic Network. The nearest seismograph was 12 km away from the centre of the sequence.
Details of the 28 earthquakes from the Tokaanu sequence for which digital waveform data were available.
Earthquakes numbered 4 and 9 were not located.
Those marked with an asterisk are a close match to those on the NZ Catalogue based on the size and approx. time, although the exact depth and location are slightly different.

There are no co-ordinates for the epicenters of the quakes available, so the map and co-ordinates have been created by hand from a sketch map within the above report and match to the original map as close as possible. The epicenters were computed using the iterative Geiger method and the original digital data recorded by the Taupo Seismic Network., a network of six telemetred seismographs that operated around Lake Taupo between 1985 September and 1991 July.

All epicentres are located inside the low resistivity structure which outlines hot and thermally altered rocks in the upper 0.5 km of the Tokaanu-Waihi geothermal reservoir.
There is no data available on the magnitudes save for the maximum size in each swarm.
The April 20th-21st swarm had a sequence of 20 events. The maximum magnitude of 16 events on the 20th was 3.1 and the sequence lasted 1 hour. The later part of the swarm on the 21st had 4 events over a period of 6.5 hours.
The 3 events of the small July 23rd swarm occurred close to the thermally active Hipaua area, the 3 events occurred over a period of 1.5 hrs and the largest event was 2.6ML.
The 18th December swarm of 5 events was over a period of 10 hours and the largest quake was a 2.1ML.

The locations are marked on the map below, the dates shown by colour.

1967 Mt. Tihia/Tokaanu quakes

2009-06-09T13:02:00.003+12:00

1967 was the first year when swarms were recorded in the Mt. Tihia/ Tokaanu area. There were essentially two sequences during 1967, the 1st with 6 events on April 20th under the NE base of Mt.Tihia south of Tokaanu, and one event centred under the summit of Mt.Tihia. The 2nd sequence of 3 events was on July 11th with 2 events located SW of Mt. Kuharua and 1 event in Waihi Bay, Lake Taupo off Waihi Village.
The other quake of 1967 was located under the lower NE slopes of Mt. Pihanga

Rotoaira/Rotopounamu Introduction

2009-06-07T08:52:00.015+12:00

The parameters of Latitude and Longitude that have been used in this research/study have been set by the earthquake swarm events of 30 May to 2nd June 2009. They are Northern Latitude -39.015 (39° 0' 54" S), Southern Latitude -39.06 (-39° 3' 36" S), Western Latitude 175.66 (175° 39' 35.9994" E), Eastern Latitude 175.79 (175° 47' 23.9994" E).
Whilst there were earthquakes outside this study area during the same periods of time, I have kept to the perameters which cover the Western and Upper reaches of Lake Rotoaira, across the Ponanga Saddle between Lake Rotopounamu and Mt Tihia, to Mt Pihanga in the east for clarity.
The maps below show the search areas as a darker shade.

Geography.
The Tongariro Volcanic Centre occupies the southern 65km of the Taupo Volcanic Zone and comprises three main volcanic complexes. In the north, the large cones of Pihanga (1,304m), Kakaramea (1,280m) and Tihia (1,147m) and smaller cones Puketopo (930m) and Pukemohono (795m) within what is known as the Rotopounamu Graben, all are extinct and are aligned NW-SE for about 10km.
The Rotopounamu Graben was formed approx. 2000 years ago after major eruptive acticity on the Tongariro Massif ceased. There are two un-named fault lines of uncertain age that run NNE-SSW on the east and west sides of Lake Rotopounamu. The lake may be consequent on ponding of drainage and so post date the faulting or it may have been an explosion crater.
Lake Rotopounamu is approx 1m2 in area and with a maximum depth of 7.5m.
South of Lake Rotopounamu are two un-named cones known as Onepoto Craters, a minimum age of 20,000 years is suggested for all cones and domes in the Rotopounamu Graben area.

Deformation of the southern part of the Taupo Volcanic Zone in repect to the Kaimanawa Range to the east is estimated at an average rate of 2.1metres per thousand years.
Recent scientific work indicates that the earth's crust below the Taupo Volcanic Zone may be as little as 16 kilometres thick. A film of Magma 50 kilometres (30 mi) wide and 160 kilometres (100 mi) long lies 10 kilometres under the surface.
Local deformation within the Rotoaira/Rotopounamu Graben is known in historic times. Hochstetter’s 1864 sketch map of Lake Rotoaira shows two peninsulas extending into the lake, one at the southestern end and another at the northwestern end connecting with Motuopuhi Island.
In 1933 Grange and Williamson published a map of the area and the southeastern peninsula had disappeared but the northwestern peninsula persisted.
Since 1973 the end of the northwestern peninsula has become separated to form Motuopuhi Island. The area of Lake Rotoaira is therefore gradually extending as this part of the graben becomes further depressed.

1975-1985 Southeastern Lake Taupo quakes

2009-05-13T13:03:00.003+12:00

There were no earthquakes recorded in the Rotoaira/Rotpounamu area covered by this category/search area. Technology at the time was limited to recording quakes above 2.5ML, and judging by the patterened locations of magnitude 3+ events the location co-ordinates were not pinpointed all that accurately anyway.
I have created this map which shows the events larger than 4.0 ML magnitude for the period just outside Rotoaira/Rotopounamu, in a radius approx. 15km from the summit of Mt Tihia.
Only the 5+ quakes are listed.

1973 Sth Lake Taupo/Tongariro quakes

2009-05-12T15:13:00.001+12:00

In 1973 there were no earthquakes recorded in the Rotoaira/Rotpounamu area covered by this category/search area. The map below shows the events larger than 3.0 ML magnitude for the year just outside Rotoaira/Rotopounamu, in a radius approx. 20km from the summit of Mt Tihia.
One interesting event was the 3.744ML on Nov. 21st, located between Red Crater and Blue Lake on Mt. Tongariro, at 119km deep.
In January 1973, Ngauruhoe ( which is south of here and is the largest and youngest of the Tongariro cones) discharged red-hot blocks of lava, and periodic activity continued throughout the year. In 1974 and 1975 there were explosive eruptions of ash, and blocks of lava were thrown as far as 3 km away. During the last violent eruption, gases streamed from the crater for several hours, producing a churning plume of ash that towered up to 13 km above the crater. This column then collapsed and formed ash and scoria avalanches that swept down the sides of Ngauruhoe, leaving trails of rubble in their wake.
