Seismic Night, Holey Night….

December 25, 2011

“You could see the panic on people’s faces. That’s the end of Christmas – it’s so unfair,” Sue Joy, florist  23 Dec 2011 

On the eve of Christmas Eve, just when things seemed to be all calm and all bright, the serious jolting started again.  Not only shepherds  were once again quaking at the sight of the quakes. No seismic Christmas truce here in Christchurch in the demolition  trenches  but lots of new sink holes- and a sinking feeling. 

As I write this, at 8am on Christmas Eve, GeoNet has reported 63 earthquakes around the wider Canterbury region over the last 24 hours.* This ended six months of relative calm for the city and will further set back  recovery as insurance companies re-start their risk raters. 

Christchurch residents hoping Christmas celebrations would be a brighter end to a bleak year are instead dealing with more seismic damage to homes, infrastructure and businesses through shaking damage and liquefaction.

Two large magnitude earthquakes on Friday heralded the new activity – a Richter 5.8 and a 6.0, the latter being the 4th largest magnitude since the seismic season started here in September 2010. 

I was upstairs at home for the first 15-20 seconds roller and was out in the garden for the second shorter, but more feisty shock, talking to our Student Job Search gardener who was just describing how he’s seen our whole house jiggle at the earlier quake when we had an even jigglier encore.

Our post World War II rough hewn rimu house is obviously very elastic and goes with the flow. It probably also helps that it is sitting on a foundation of crusher dust from the old Halswell Quarry across the road which acts like base isolation. The grandfather clock downstairs and the cuckoo clock upstairs kept going through the first but were stopped dead, but ever to go again, by the second. 

Once again we were fortunate but a lot of people, especially on the east side of town, were not with power cuts and liquefaction silting up  parts of the eastern suburbs for the fifth time in 15 months.* Not the Xmas present they were expecting. There appears to have been a Mercalli migration further east. Most of the recent quakes were centred in faults below Pegasus Bay, off the coast of Christchurch, within 8-21 kilometres of the city centre, and many were less than 10km deep. 

Whatever the new physical damage from these earthquakes-and there were scores of minor injuries-  they have further set back the recovery of the city. Retailers who have struggled to survive were dealt a major blow as stores packed with Christmas shoppers were evacuated. Some face being shut on the busiest trading days of Christmas Eve and Boxing Day. 

 Essential tremor 

“Essential tremor” is an involuntary trembling that affects millions of people. In October 2008 Eddie Adcock, 70, a bluegrass maestro whose career was being hampered by a hand tremor was asked to pluck his banjo during brain surgery, so surgeons could pinpoint the right part of the brain to work on. During the procedure surgeons prodded and inserted electrodes into his brain to suppress the nerve cells causing his tremors. When the surgeons found the right part of the brain, the plucky Adcock instantly regained his ability and was able to play at full speed once again*. 

The Canterbury land mass above and below the waterline seems to have developed a chronic case of the sesmic ETs. In this case the geotechnical explorations and explanations can’t by their nature be as precise as Adcock’s half hour. Nor can they give the same instant feedback in any predictive sense, let alone bring about a cure.

For that reason the latest tremors have literally sent shock waves through the psyches of people here who were just starting to relax into the Christmas spirit and contemplate a happier and more stable New Year. For some it was the last straw:
“Had enough now   #52   17 min ago   Thats it. We cant do this any longer, the kids are upset, wife and I cant sleep, the best of the city is gone, we are going too. Sorry to those we are leaving behind to rebuild and tough it out. Family and prospects in Melbourne.*” 

But most, not so badly affected, will stay and hopefully display the spirit and dogged determination needed by new pioneers. Before this latest blitz about half the commercial buildings in the central city have either already been demolished or are about to be, including our former offices. There could well be some new candidates.

This Yuletide in this part of the world it’s just got that much harder to sleep in heavenly peace. But many of us still have a lot to celebrate so best wishes for the festive season, no matter how restive.

Heartfelt Lake Taupo Cycle Challenge

December 7, 2011

Finished!

“Swaying pine trees, brutal wind gusts… put 9000 cyclists to the test in the annual Lake Taupo Cycle Challenge event…. Strong wind gusts made riding treacherous for road and mountainbike riders in the 35th annual 160-kilometre lake circuit on Saturday. Large pine trees swayed precariously in 85kmh wind gusts. Cyclists, pedalling into energy-sapping headwinds, negotiated scattered branches and debris…”  Dom.Post 28/11/11* 

This time last week I was a tortoise on two wheels- definitely not a hare- in the 35th Lake Taupo Cycle Challenge. At least I didn’t turn turtle in the blustery conditions. Quite a few entrants didn’t even start.

After a 6am start in the slow pack, my time of 9 hrs 46:57 in the 60-69 years solo 160 k division (I just qualified-it was the day before my 70th birthday) put me 328th in the division but, apart from the timing equipment, who’s counting? It was great just to finish again in the conditions, described as “one of the more difficult rides on record”, in reasonable condition. Three months after my last Taupo outing in 2008, I had two stents inserted after a coronary.  

 New Gear

My previous three Taupo rides since 2006, once in the 40K relay and twice in the 160k solo ride, were on my old second hand road touring bike which I bought off a departing Swedish cycle tourist who wasn’t murdered in 1991. It came complete with four panier bags for camping gear.

For three years I was the only Taupo entrant with paniers and a rear vision mirror. Bikes are built either for speed or for comfort and mine was in the latter category, unlike the emasculatory razor seated road bikes that are de rigueur.

This year was different. My Canadian mate Gord Miller, doing the Solo Challenge at Taupo for the second time, has tried for years  to convince me to get a more suitable steed for the event. It was my daughter Sandra who applied the killer psychology. She has an Events and PR company and does the public relations for the Pure Black Cycling Team*

First she got me some sporty PB riding gear. Then she persuaded me to get a sleek carbon fibre Cadent* bike from Avanti, Pure Black sponsor, to match the outfit. It’s  a speedy machine with a slightly ‘softer’ attitude for riders who want something a little more relaxed. It made all the difference, especially with the wind, and the Geltech cover over the original seat was almost comfortable.

I did also add a snappy Vaude clip on under the seat detachable carry bag. I like to be self sufficient and carry more food and water, extra clothes and tools than most, despite the support stations en route, though stories about an on board kitchen sink are calumnies.

Pure Black riders were 1st and 2nd over the line. I was 4236th  overall so they were probably pleased I wore a high viz. vest over my sporty PB  racing shirt. 

I was also helped this year on the nutrition front by Shane Miller, Gord’s son, a gym instructor and high performance coach from Ottawa. Last time I cramped up 10 times on Hatepe Hill at the 132 k mark. This time nary a twinge after a good balance of protein and pasta and several magic potions during the ride. None would have got Lance Armstrong into trouble.

My father Gordon Lukey was a well known long distance cyclist and endurance record holder and all round iron man in the days of gravel roads and no gears. He would have been amused at the hi tech nature of cycle riding today and the fancy fashion and food but he would have applauded the numbers participating.

Life cycle

The biblical age is a bit hard to come to grips with, though these days maybe it’s only mature middle age, at least for the fortunate survivors thus far. The big 70 is inevitably accompanied by a bit of philosophical introspection.

The old black joke is ”A fatal coronary is nature’s way of saying ‘slow down’. Sadly, just a few weeks ago the old friend I usually stay with when doing Taupo died suddenly while still in top gear in a top corporate job with lots of demanding overseas travel. Earlier in the year he put off accompanying his sister on a cycle tour of France because of the demands of the business.

Only three weeks ago, on a Rotary cricket tour of NSW- (geriatrics in pursuit of hattricks-or even a single wicket) – the player in our opponents’ team in the third game, who had just received Man of the Match award, collapsed and died. Sad, but what a way to go.

It’s important to keep doing things you like to do or that provide new challenges while you can. Always at my back I hear times winged chariot…
