Huge Earthquake on New Zealand Islands


A destructive earthquake that struck New Zealand two years ago has left its two main islands edging towards each other, and one city sinking, according to scientists.

But the margins are minimal with the gap between the North and South islands narrowing a mere 35 centimetres (13 and a half inches), while Nelson at the top of the South Island has sunk by up to 20 millimetres.

The magnitude 7.8 earthquake on November 14 initially pushed the two islands several metres closer and the unsettled fault lines have since nudged the southern landmass further north.

However, the gap from Cape Campbell, where the main rupture ended in the South Island, and the New Zealand capital Wellington at the bottom of the North Island is still more than 50 kilometres.

At least 25 fault lines ruptured in the 2016 quake, which earthquake geologist Rob Langridge from the government’s geoscience research organisation GNS Science said made it one of the most complex earthquakes observed anywhere in the world.

Fellow GNS scientist Sigrun Hreinsdottir told the Stuff website on Friday that the sheer number of faults made it difficult to distinguish which was responsible for the post-quake creep.

“In reality we are having all this creeping going on and the question is, which (fault) is the dominant factor?” Nelson, at the top of the South Island had fractionally slumped.

“The whole area is going down maybe 10 to 20 millimetres. It’s not a huge amount but it is observable at our sites,” she said.

GNS principal scientist, Kevin Berryman, said all earthquakes of 7.5 and above are very complex but it was “certainly unusual” for 25 faults to rupture simultaneously.

The Kaikoura earthquake struck just after midnight and raced north from the middle of the South Island towards Cook Strait covering 170 kilometres in about 74 seconds.

New Zealand lies in the collision zone between the Indo-Australian and Pacific tectonic plates, part of the Pacific Basin Ring of Fire, and experiences more than 15,000 earthquakes a year although only 100-150 are strong enough to be felt.

7 Cleaning Tips for Sewer and Drain

There’s nothing more messy and problematic than a clogged drain. Not only troublesome, it also causes hygiene issues and deteriorate the maintenance of the house.

Water all around, bad smell, and dirty home…a hassle we all try to avoid as much as possible.

But how does a sewer drain get clogged?

Each drain in our homes flows down to a larger drain branching together into the main drain or sewer line. Large pipes from homes are connected to the main sewer lines and this is how they get you rid from the dirt water and other waste matter.

There are some vent pipes also that are integrated into the main system along with the branch drains. These vent pipes don’t allow vacuum to be created.

Clogging occurs if somehow vacuum is created in the vent pipes. The vacuum doesn’t let the water flow down and causes clogging and allow the sewer gas to spread inside the home. This results into water puddled under the sink, toilets, laundry lines and kitchen area and causes obnoxious smell.

How to Get Rid of Clogged Sewer and Drain?

A clogged drain must be unclogged to let the dirty water flow out of your home. Although they pose big cleaning and maintenance challenges to the home owners, but they are not always that difficult to be cleaned.

The following are some tips to help you identify easy tricks to unclog the sewer and drains.

  1. Rely on Home Remedies

A drain is not clogged just over night. A slight negligence during regular use is usually the main reason for sewer and drain clogging.

But it is not necessary that every time you need to call for professional plumbers to resolve the issue. Some simple home remedies can be very useful in this regard.

Boil a kettle of water and gradually pour this boiling hot water into the clogged lines in two to three stages. This simplest solution does wonders.

Another home ready is to use vinegar and baking soda. Take 1/3 cup of each ingredient, mix them and immediately pour into the drain. It will result into fizzing that removes the blockage inside the drain. This must be left overnight for best results. Flush with hot water the next morning.

  1. Use Enzyme Cleaners

Enzyme cleaners are very effective in keeping the sewers and drains clean. Using them at least once every month is advisable.

There are various chemical based cleaners available in the market. These enzyme cleaners are safe to be used for drains as they don’t damage the pipes, environment and health of the residents. The commonly available chemical cleaners are hard in nature and may damage the pipes. They also cause corrosion, which is again undesirable.

Hence enzyme cleaners are better option to keep the drain clean.

  1. Get rid of Unwanted Stuff in the Drain

Hairs, plant roots and other such unwanted stuff enter into the drains and block them. This is the most common household reason for the sewer lines and drains to be blocked.

Getting rid of them is essential and easy too.

A mesh strainer drain trap is the right call in this case. Placing this drain trap can be very helpful in catching any sort of debris going directly into the drain. The mesh strainer drain trap can be placed in kitchen, bathrooms and laundry drains.

Another way is to perform Rooter cleaning once a year. This detailed cleaning helps you avoid chances of serious clogs in the future.

  1. Watch out for your Flushes

Careless draining is another reason for some serious troubles in the drainage system. While flushing out, it is important to ensure that the waste matter is soluble.

Usually people flush away wipes into the drain without realizing that these wipes may develop a blockage later on. Only toilet paper and waste should be flushed away.

Sanitary napkins must not be flushed out this way. Otherwise they will clog the lines causing huge plumbing issues that can only be solved using professional help.

A slight care while flushing out can be a big savor!

  1. Repair Leaked Pipes

Never ignore if any of the pipe in your home is leaking. Sometimes the leakage is because of any damage to the pipe. It might be corrosion too that is damaging the pipe.

Whatever is the reason, the drain pipes must be repaired immediately. A slight leakage may result into uncontrollable damage to the home plumbing system. The leakage can be identified through water puddle around kitchen sink, lose tiles next to the tub, mold spots on the wall and peeling paint.

Should you notice any of such signs, it is suggested to figure out whether there’s a leakage from any of the pipes. When a leakage in pipe is caught, call your trusted plumber for quick repair.

  1. Insulation of Pipes

Winters are a challenging season for the drains too. Water expands due to a drop in temperature, causing the lines to clog sometimes.

Though occurs rarely, especially in extremely cold weather, but when happens bring a lot of inconvenience to the house owners.

Poor pipe installation and lack of insulation are the common causes for frozen pipes. Rather than ignoring the issue, it is suggested to wrap the outside of the pipes with proper insulation to prevent the hassle. A thicker insulation is the best, but even household insulation will be sufficient.

Pipe insulation is usually made of polyethylene or fiberglass. Tubular insulation is another of the trick proved to be effective in some cases.

  1. Get rid of Oil and Grease

The kitchen sinks are more prone to the clogging caused by oil and grease. Try as much as possible to keep the oily stuff away from the drains. Though take longer in building up, but oil and grease are the toughest to get rid of in the long run.

Getting rid of these nasty stuff is frustrating. Mixing hot water with soap sometimes help in washing out grease. But this trick is not helpful always.

N case of tough clog, a caustic cleaner is much helpful. Pour the cleaner into the drain with standing water and leave it for an hour or more. Using compressed air is also found to be helpful for troublesome grease.

Last Word

Sewer and drain lines must be prevented from any sort of clogging which occurs as a result of daily use and regular wear and tear. The tips discussed here can be very handy and useful in doing this job with ease.

Try them out and get rid of clogged drains.

How to break out of your decorating rut

How to break out of your decorating rut

You might like to see your home as your castle, but even medieval knights didn’t take their castles for granted. Indeed, like they knew that enemy armies could breach their castle if they didn’t regularly bolster its defences, your home could look tired if you resist ever tweaking its style.

Perhaps it isn’t a moat you have fallen into, but instead a comfort zone that stops you ever changing the seating, art or other decoration. Here are tips for reinvigorating the residence.

Peruse social media pages

There’s a regularly updated treasure trove of information on social media – including exciting ideas for making the inside of a home look nicer.

You might actually have a favourite designer or design guru whose interior style you especially like. If so, you could not only follow their accounts on sites like Instagram and Pinterest but also check out who they follow, as D’Marge recommends.

Take inspiration from the movies

Yes, that’s right – your decorating rut could be broken if you head to the cinema or re-watch those film DVDs or Blu-ray discs you’ve got at home. You might not usually be in the habit of closely looking at the interiors in films, but now could be a good time to change that.

This can be wise because films are, of course, intended to look good – and, if you do see a particularly alluring room, you might later find an interview with the set designer for more insight.

Add some new and interesting accessories

If you want to give your home a major visual overhaul, you don’t strictly need to make large, sweeping changes to bring about that effect. What do we mean?

Basically, that you could make your home look a lot different just by swapping, adding or removing accessories. You could purchase some new blankets, rugs and window treatments; it can all add up to a pleasingly inexpensive way of giving a home a makeover.

Be inspired by art and nature

Artists obviously know what looks beautiful; therefore, simply looking around a local art gallery or checking out some street art could give you some intriguing new ideas. You might even spot some eye-catching artwork that is on sale and would look just right on a particular wall of your house…

However, don’t overlook the artistic abilities of Mother Nature, either! While out and about, drop by a garden centre and see if it stocks some plants that could also visually complement your home.

Put a familiar space in your home to a new use

One of the reasons for your rut might be that you have long neglected rooms which have much more potential – and quirky potential – than you have realised.

Maybe you have a garage, but not a car inside it. Perhaps there’s also a conservatory, but it lacks adequate insulation to be usable all year round. It might be possible for either space to be improved by a company offering services like roofing in Newcastle upon Tyne and other settings.
