New Zealand’s mysterious ‘silent earthquake’ could help predict future tsunamis | Instant News

What is slow slip? Video / GNS Science

An earthquake that occurs slowly and quietly deep beneath the North Island can be the key to predicting future earthquakes and tsunamis generated by our biggest fault.

A million dollar, three-year project will increase scientists’ understanding of
Earthquakes “slow” along the Hikurangi Subduction Zone.

Scientists believe the subduction zone, which runs along the east coast of the North Island, could produce “megathrust” earthquakes larger than the scale of 8, such as the one that created the tsunamis that devastated Indonesia in 2004 and Japan in 2011.

The worst case scenario of a major Hikurangi event could include thousands of deaths and injuries, and billions of dollars worth of property losses.

But slow-slip earthquakes – where plate boundary faults release slowly buried tension over days to months instead of seconds in a typical earthquake – can help us better gauge threats.

Their discovery 20 years ago has revolutionized seismology and our understanding of fault mechanics.

Even though it happens off the east coast every few years, no one feels it when it happens – and the driving force remains unclear.

The new project, led by GNS Science, is designed to detect subtle physical changes in a fault before a slow-slip earthquake occurs, to uncover the mechanisms that regulate its timing.

“It will clarify if there is an observable physical change in the fault that could allow the development of a more accurate estimate of when the fault might fail, either in a slow earthquake or, possibly, a fast earthquake,” said project leader Dr Laura Wallace.

Tantalizing evidence has emerged in recent years that increased water pressure near the fault exerts great control over New Zealand’s slow-slip earthquakes.

GNS seismologist Dr Emily Warren-Smith said if this build-up affects slip times, then monitoring water accumulation in the fault could allow better forecasts for slow and possibly fast earthquakes in the future.

But it is possible that the change in fluid pressure within the fault may be a symptom of a slow earthquake rather than a direct cause, said Wallace.

Alternatively, there may be other processes such as a steady increase in stress from tectonic plate motion that controls the tempo of a slow slip earthquake.

The project aims to resolve this dichotomy by installing large-scale submarine and land monitoring instruments in the southern Hawke’s Bay and Wairarapa.

It will monitor changes before, during and after the regularly expected recurring slow slip events offshore in this region in the next two years.

Wallace said the project would establish new ground in seabed geodesy and help put New Zealand at the forefront of global efforts to monitor offshore faults that can produce large earthquakes and tsunamis.

The team departed this weekend aboard the Niwa research vessel Tangaroa to carry out the first set of seabed sensor deployments.

“This project will generate new evidence-based information that will aid significantly in planning and preparedness and make New Zealand safer and more capable of recovering from a major earthquake.”

A separate voyage to the Hikurangi subduction zone – where the Pacific Plate is plunging downward, or “plunging” below the North Island’s east coast – has just finished.

US scientists recently dropped their own specialized equipment onto the ocean floor to visualize subsurface structures, and investigated how fluid is distributed within the sediments.

Program leader Dr Jess Hillman, from GNS Science, said this will allow scientists to better understand how fluid movement is related to activity in our largest offshore faults and the generation of gases beneath the ocean floor.

Shipping specialist Dr Peter Kannberg, from the Scripps Institution of Oceanography in the US, said earthquakes, the stability of the seabed slopes and the release of seabed gases were all regulated in part by the presence of fluids.

“Our instrumentation can detect where this fluid is on Earth, enabling us to better understand the role of fluids in regulating these natural hazards.”

The new three-year project is supported by a $ 960,000 grant from the Marsden Fund.

New Zealand Weather: Summer is spring for some, before the rains and rains arrive | Instant News

New Zealand

MetService national weather: November 13-15

Spring has turned into a countrywide summer this weekend, thanks to a high-pressure system in the north and warm westerly winds blowing in the south.

Auckland residents came out enjoying the sunshine yesterday after avoiding a possible lockdown with the latest Covid case genomically linked to a Defense Force cluster.

It was as if summer had arrived in Mission Bay with kids going in and out of the water – and the sand.

The summer mood continues into the day as temperatures in most major centers will hit 20 ° C, with Christchurch, Blenheim and Timaru expecting summer temperatures of 25 ° C and Tauranga 24 ° C.

Upper North Island centers can expect highest temperatures in the lowest 20s – Auckland and Hamilton should hit 22C, Rotorua 21C and Napier 23C.

Temperatures on the North Island are nearly normal for the time of year, but above average for parts of the South Island thanks to nor’westers, says MetService meteorologist Kyle Lee.

“In the east we’re talking 4C to 7C above average.”

Cooler days in the western and southern parts of the North Island – Wellington would be fine but with temperatures of 18C and New Plymouth, also good, 19C.

Most of the place will be dry, with the exception of a few parts further south, Lee said.

“The weather today is quite good. There is a bit of high pressure that keeps most of the country fine.”

Heavy rain could ruin parties in Otago, Southland and parts of Westland and a heavy rain warning has been issued for Fiordland – rain is expected to fall as high as 150mm before 9pm tonight.

Meanwhile, Sunday sunshine in most parts of the country will make way for some to kick off a humid work week.

North Islanders can expect heavy rains to spread over much of the island, from Northland to Wellington, and from Taranaki to the east.

It will be warm in Auckland, with temperatures as high as 22 ° C, but it will rain from late afternoon, with a similar story in Hamilton.

A brief afternoon of rain is expected in Wellington tomorrow, with temperatures as high as 18C.

On the South Island, rain and rain are expected to occur in many places during the day, before it clears up at night.

Six regional teams prepare for final matches | Sports | Instant News

It’s not a normal football season… to say the least.

All of the challenges caused by the COVID-19 prompting the start of the fall sports season have been well documented to date. Nothing has changed there.

And we’ve learned about the extreme actions football coaches – especially the seven head coaches of public schools – have to do just to get their team out.

The added weight of face masks, health protocols and social distancing is only the surface scratches of the difficulties that have been added to the chance they all do what they love – coaching football.

And it will end as soon as it starts.

After this weekend’s games, Washington County schools will “pause” their school years. All activities on campus will be suspended for at least three weeks, starting Monday.

That could very well end the 2020 football season, reaching the halfway point of a six-game season that started late.

Only North Hagerstown, South Hagerstown and Smithsburg can play for three weeks. Williamsport, Boonsboro and Hancock will only play twice, while Clear Spring will play its only game on Friday night.

It is almost right that a season that started late had to end early.

South Hagerstown (1-1) in Williamsport (1-0)

Series record: South Hagerstown, 32-16

Last meeting: 2019 – South Hagerstown 48, Williamsport 6

This could be a matter of patience vs. excitement.

The South continues to search for its identity. The rebels – usually the big boys on the block – needed a big second half to beat Smithsburg after losing their opener to North Hagerstown in extra time.

The Rebels continue the “run till you stop us” mentality as new midfielder Lance Ford continues to develop.

The Southern Defense was solid, but struggled at times.

Williamsport caused quite a stir in last week’s win over North.

Quarterback Jared Snow got the foul with five running backs and three main receivers, keeping Hub behind them. Snow’s ability to run and escape pressure is added to the package.

Wildcats are very physical and able to control top North players in defense.

Players to watch: South Hagerstown – RB Ron Blocker; Williamsport – QB Jared Snow.

Forecast: Williamsport 30, South Hagerstown 21

Boonsboro (1-0) in North Hagerstown (1-1)

Series record: Tied up, 22-22

Last meeting: 2019 – North Hagerstown 48, Boonsboro 47

For the last 24 years, this battle has been fierce.

The Warriors took a seven-game winning streak starting in 1996, followed by two for Hubs (2003-04), three for Boonsboro (2005-07), four for North (2010-13) and another five for the Warriors (2014-18).

North, with a great late night, got the win last year.

But this year, Hubs is struggling with a pass, despite fast forward Devon Napier. The violations continued with running by AJ Cook and Bray Alexander. The defense is prone to short pass play.

Boonsboro appeared efficient in their opening win over Smithsburg two weeks ago, but sat through last week’s unscheduled bye.

The Warriors’ faces have changed – including in coaching, when Pete Yurish replaces Clayton Anders, who retired after last season – but Boonsboro continues to use his trademark offense. Quarterback Brady Ingram seems comfortable and running back Brayden Ord and Ty Unger receivers have some experience.

By the way, Yurish was the North’s defense coordinator before taking over the Boonsboro job.

Players to watch: Boonsboro – WR Ty Unger; North Hagerstown – LB Keith Johnson.

Forecast: Boonsboro 28, North Hagerstown 14

Smithsburg (0-2) in Clear Spring (0-0)

Series record: Smithsburg leads, 15-1

Last meeting: 2019 – Finish Spring 24, Smithsburg 22

This one is anyone’s guess.

Smithsburg continued to thrive under coach Vince Ahearn’s new system, but only had 13 points from the first two games.

Clear Spring is the least known after spending the first two weeks of the season in quarantine. The Blazers did not resume training until Tuesday.

Clear Spring will lean on field play behind Xavier Blair and Jayden Washington, and have quarterback experience with Eric Bender. They also play in defense.

Players to watch: Smithsburg – LB Josh Black; Clear Spring – RB Xavier Blair.

Forecast: Complete Spring 20, Smithsburg 19

New Zealand Weather: Wet for the most part, chilly in the south | Instant News

New Zealand

MetService National weather: 6-8 November.

Erratic spring weather continues across the country today, thanks to the lowness of the Tasman Sea across the North Island and cold winds moving towards the South Island.

Slow-moving low waves arrived overnight, bringing rain and torrential rains to much of the North Island and the summit of the South Island, with heavy rain guarding some parts of the two islands today, said MetService forecaster Cameron Coutts.

It is the Kaikōura and northern Canterbury ranges, Nelson ranges west of Motueka, Mount Taranaki, the central mountains of the North Island and east of the Bay of Plenty, and west of Gisborne.

There is also a risk of thunderstorms over the upper North Island, particularly in the Coromandel, Bay of Plenty and Taihape, this day and night, Coutts said.

Temperatures will be cool in the north – Auckland is expected to be 21C, Hamilton 20C and Tauranga 23C, while Wellington will be 16C.

At the same time, cold weather comes to the South Island, bringing rain, heavy rain and – in some places above 600 meters – snow.

Road snowfall warnings have been in place for some of the South Island’s alpine trails, with rain expected to turn to snow this morning on the Crown Range, Lindis, Arthur’s and Porters’ pass, and during this morning on the Lewis Pass.

The front subsided during the day before moving east of the island, Coutts said.

It will be a cold day in late spring – forecast for 14C in Christchurch and 13C in Dunedin.

Conditions will be similar tomorrow and Tuesday, with heavy rains likely to the east of the North Island and a hurricane south in the south of the island due to the strong southeastern flow across central New Zealand.

The South Island will be fine in the west and south, with clouds and possibly heavy rain to the east and north, he said.

The low temperatures will drift away in the middle of the week, bringing relief to those tired of the sometimes harsh weather of the north.

“[There’ll be] southwest stream, so it will be cooler and drier across the country. “
