(Update 10:36 A.M. 2/22/2011: I was curious to know if aliens had taken notice of this event – how could none notice, especially if their is a hidden communications network, like an alien Internet – and after a search saw this link at the bottom of Google: UFO OVER NEW ZEALAND EARTHQUAKE 21 FEB 2011. I segmented the relevant frames below and added some arrows to save people time, and also because the video is annoying and pretentious. The pictures are below. The UFO seems to go down into the column of smoke, perhaps to hide its initial entry, but then goes forward:)

Earthquake of 7.1 magnitude hits New Zealand
9/3/2010 7:42 P.M. EDT by Gyles Beckford WELLINGTON (Reuters) – A major earthquake hit New Zealand’s second biggest city Christchurch early on Saturday, bringing down power lines, ripping up roads and wrecking building facades, but authorities reported no deaths. Authorities declared a formal civil defense state of emergency to coordinate recovery operations in the city, which has a population of about 350,000 people, after facades collapsed into streets, crushing cars and blocking roads. Two men suffered serious injuries and police closed off the central business district. The earthquake had a magnitude of 7.1 and a depth of 10 kms (6 miles), hitting the South Island city and a large surrounding area of farms at around 4.35 a.m. local time (12:35 p.m. EDT Friday). “There’s a lot of damage that I’ve been able to observe in the central city area, mainly of the old brick and masonry buildings, a number of those have got walls that have fallen into the street,” Christchurch mayor Bob Parker told Radio New Zealand. The city’s hospital said two men had been admitted with serious injuries, one hit by a falling chimney and the other cut by glass. It had also treated a few other people with broken bones, cuts and grazes. Police said there were several instances of looting, which had been quickly contained. In the suburbs many houses had broken windows, toppled chimneys, cracked walls and items thrown off shelves. Power was out over a large area of the city and surrounding region as circuit breakers were tripped at substations, but was being progressively restored after safety checks. Water and sewage services were also disrupted, and there were reports of subsidence in some roads. RURAL EPICENTRE Officials were checking how severe the damage was in rural areas, closer to the epicenter, west of the city. Ray O’Donnell, owner of a hotel in Darfield, a small farming community around 20 kms (12 miles) west of Christchurch, said large cracks had appeared in rural roads near the epicenter. GNS Science, the New Zealand government seismological agency, revised its reading of the quake to magnitude 7.1 from an original 7.4. The U.S. Geological Survey initially reported it at 7.4 but later revised its figure to 7.0. The city’s airport was shut as the runway and facilities were checked, and the railway network and bridges throughout the region were also being checked for damage. The quake was felt as a long rolling motion lasting up to 40 seconds. The area was continuing to feel aftershocks as strong as magnitude 5.2. “It was a real rocker, and (we’re) still getting aftershocks. (It) felt like the house was flying on a whirlwind,” Tessa Hay, who lives around 12 km north of the city, told Reuters. Because the quake occurred inland there was no danger of a tsunami. “No destructive widespread tsunami threat exists based on historical earthquake and tsunami data,” the Pacific Tsunami Warning Center said. New Zealand scientists record around 14,000 earthquakes a year, of which around 20 top magnitude 5.0. The last fatal earthquake in the geologically active country, caught between the Pacific and Indo-Australian tectonic plates, was in 1968 when an earthquake measuring 7.1 killed three people on the South Island’s West Coast. – Source [There is a slideshow with this story] Christchurch, New Zealand Closed Off After Massive Earthquake 9/4/2010 by Shar Adams The city centre after a 7.1 magnitude earthquake struck 30km west of Christchurch at 4:35 am this morning September 4, 2010 in Christchurch, New Zealand. (Kurt Langer/Getty Images) Christchurch on New Zealand’s South Island, has been closed to the public after a massive earthquake, 7.1 magnitude, crumpled roads and buildings in the Canterbury area. Central Christchurch has been completely cordoned off to the public such was the damage, New Zealand’s One News reported. Civil Defence Headquarters has called a state of emergency, activating the national crisis centre, as reports surfaced of collapsed buildings, cracks in bridges and roads, crushed cars and disrupted water and sewage pipes. While there have been no deaths reported to date, a number of injured have presented at Christchurch Hospital, Radio New Zealand reported. The quakes epicentre was about 55 km (35 miles) north-west of Christchurch and at a depth of 12k (7.5 miles.) Civil Defence have declared a state of emergency and there has been considerable damage across the city and surrounding areas. Cell phone networks have reportedly gone down and electricity has been cut to around 75 percent of the area. Although Civil Defence is urging people to remain calm and to stay in their homes, people in the towns of New Brighton and Brookland have been warned they may have to evacuate if water and sewage continue to flood the area. Douglas Brown, who lives close to Christchurch, said he could see the effects of the quake right outside his door. “You can put your fist into the cracks in the road,” he [said by phone]. Mr Brown also said there was silt like water bubbling up through the ground. – Source New Zealand earthquake ‘damaged 100,000 homes’ from bbc.co.uk 9/6/2010/07:28 ET A building damaged by Saturday’s earthquake is demolished in Christchurch (6 September 2010) Despite the widespread damage caused by the earthquake, no-one was killed Almost two-thirds of the 160,000 homes in and around Christchurch have been damaged by Saturday’s earthquake, New Zealand’s prime minister has said. John Key said many had been damaged beyond repair, and that it might take some time to discover the damage to the region’s underground infrastructure. A state of emergency in Christchurch has been extended until Wednesday, and the city centre remains cordoned off. Experts have warned a major aftershock could rock the area in the near future. More than 80 aftershocks have been recorded since Saturday’s 7.0-magnitude tremor, the strongest of which had a magnitude of 5.1. “It is still possible that we’ll have a magnitude 6 in the next week, and people ought to be aware of that, particularly if they are around structures which are already damaged,” Ken Gledhill of the Institute of Geological and Nuclear Sciences told the NZPA news agency. “For a shallow earthquake like this, they will go on for weeks,” he added. “And if a building is badly damaged, it won’t take much shaking to push it over.” Despite the widespread damage caused by the strong earthquake, no-one was killed and only two serious injuries were reported. Mr Key, who visited earthquake-stricken parts of the country’s South Island over the weekend, said 430 houses and another 70 buildings had already been earmarked for demolition by assessment teams. About 100,000 of the 160,000 homes in the Christchurch, Selwyn and Waimakariri areas had sustained some damage, he added. “I was awe-struck by the power of the earthquake and the damage it has caused in the city,” he told reporters. “It was miraculous that nobody was killed.” Children play in a damaged road in Christchurch (6 September 2010) Schools will remain closed for the next two days to allow safety checks The cost of repairs has been estimated at NZ$2bn ($1.44bn; £930m). Most households and businesses were expected to claim from their insurers and the Earthquake Commission (EQC), officials said. Mr Key said the central government planned to provide at least 90% of the funds needed to rebuild the area’s water, sewerage and road networks, the overall damage to which had yet to be fully assessed. “The above-ground damage is obvious, but it could take some time to understand just how much damage there is to underground infrastructure.” The prime minister said the earthquake would have a short-term negative impact on economic growth, but that the loss “would be more than made up by the stimulus impact that takes place with the rebuilding programme”. Meanwhile, Christchurch mayor Bob Parker extended a state of emergency for another two days as troops were deployed throughout the city to help police secure streets and badly damaged businesses. A second nighttime curfew to protect against looting was lifted on Monday at 0700 (1900 GMT Sunday), while another is planned for Monday night. About 200 people whose homes were damaged spent the night in shelters. Power has been restored to 90% of the city, and the water supply has resumed for all up to 80%. Those with running water have been warned not to drink it because of contamination from broken sewage pipes. “You have to boil your water very carefully,” resident Oriana Toasland told the BBC. “You’re not allowed to flush the toilet because there are problems with the sewers. So we don’t know how long this is going to go on for as well.” Schools will remain closed for the next two days to allow safety checks. Some residents told the BBC that there had been delays in getting officials to assess the damage to their houses, and basic foodstuffs were in short supply. Mr Parker told the BBC that the magnitude of the destruction had only now dawned on the city’s 386,000 residents. “It’s now into the third day since the quake and that initial adrenalin has been replaced by a great deal of tiredness,” he said. “People’s spirits in some ways are starting to just sag a little more as the reality of what’s in front of all of us really comes back. What about the job? What about the business? What about the schools? When is this going to be fixed, when will life get back to normal?” he added. New Zealand lies at the southern end of the so-called Pacific Ring of Fire, and above an area of the Earth’s crust where the Pacific Plate converges with the Indo-Australian Plate. The country experiences more than 14,000 earthquakes a year, of which only about 20 have a magnitude in excess of 5.0. The last fatal earthquake was in 1968, when a 7.1-magnitude tremor killed three people on the South Island’s western coast. – Source Massive earthquake sets back NZ economic recovery 9/6/2010 by Rob Griffith contributions from Ray Lilley from Wellington, NZ CHRISTCHURCH — New Zealand’s prime minister warned Monday that the country’s economic recovery will be hurt by the weekend’s powerful 7.1-magnitude earthquake that smashed buildings and wrecked roads and rail lines in the city of Christchurch. The aftereffects of the temblor are still coming to light. Residents in a new subdivision in a southern suburb were evacuated Monday from their houses, which became mired in deep layers of silt that spewed from the soft ground as it turned to liquid under pressure from the quake. “We thought we were having a tsunami,” said homeowner Lalita Sharma. “We stepped outside into knee-high liquid. We thought the house would sink.” Mounds of sand covered front lawns and driveways, and some houses had been ripped from their foundations. A driveway that had sloped upward from the road was now flat, the rose garden buried in sand. Army troops have taken control of central Christchurch to help police secure streets and badly damaged businesses in the worst-hit center of the city. The area remained cordoned off and under nighttime curfew, with only building and business owners allowed access. “There will be considerable disruption to the (regional) and national economy in the short term,” but activity should pick up as reconstruction gains momentum, Prime Minister John Key said. The country’s economy has now recorded two quarters of minor growth after struggling to escape 18 months of recession. The quake struck at 4:35 a.m. Saturday near the South Island city of 400,000 people, ripping open a new fault line in the earth’s surface, destroying hundreds of buildings and cutting power to the region. No one was killed, and only two serious injuries were reported. Key, who toured the city’s damaged areas over the weekend, said 430 houses and another 70 buildings, many of them older structures, were already earmarked for demolition because of damage caused by the quake. Around 100,000 of the region’s 160,000 homes had sustained some damage, he said. “I was awe-struck by the power of the earthquake and the damage it has caused in the city,” he told reporters. “It was miraculous that nobody was killed.” A quake-damaged building partially collapsed into a suburban street Monday and officials took urgent steps to bulldoze and remove it. There were no injuries reported. “Police had a unit going past just as it happened and they managed to stop and block (off) the road,” Inspector John Price said. Key said the earthquake would have a short-term negative impact on economic growth, but that loss “would be more than made up by the stimulus impact that takes place with the rebuilding program.” The government plans to pay at least 90 percent of the hundreds of millions of dollars needed to rebuild the city’s water, waste water and road infrastructure, Key said. Economists agreed the immediate economic outlook for quake-ravaged Christchurch is bleak, but noted reconstruction would provide a boost to a struggling construction sector next year. “I think people are going to be pretty conservative over the next three months. What we are seeing is … negative growth in the near term,” ANZ Bank chief economist Cameron Bagrie said. More than 80 aftershocks, ranging from magnitude 3.2 to 5.4, have rocked the region since the major quake Saturday. Rain was falling Monday in the nearby Southern Alps and foothills, increasing the risk of flooding. Civil defense officials warned that stop banks, or flood protectors, weakened by the quake may fail to hold rising waters. Engineers were inspecting the banks Monday. Around 150 people have been evacuated from a trailer park near the Waimakariri River as a precaution. New Zealand sits above an area where two tectonic plates collide. The country records more than 14,000 earthquakes a year – but only about 150 are felt by residents. Fewer than 10 a year do any damage. New Zealand’s last major earthquake registered magnitude 7.8 and hit South Island’s Fiordland region on July 16, 2009, moving the southern tip of the country 12 inches (30 centimeters) closer to Australia. – Source

New Zealand earthquake: Christchurch hit by aftershocks
9/7/2010/11:57 P.M. BST
Christchurch was hit on Wednesday by the most damaging aftershock since a devastating 7.0 quake, forcing evacuations and cracking a major road tunnel in the New Zealand city. The 5.0-magnitude aftershock struck at 7:49 am sending residents rushing into the streets, cutting already fragile power supplies and bringing down loose material from already damaged buildings. The aftershock, the latest in a series, was a shallow six kilometres deep and much closer to the city centre than Saturday’s quake, which caused billions of dollars of damage, seismologists said. “It was a devastatingly, vicious sharp blow to the city,” Bob Parker, the mayor of Christchurch said. “This was a terrifying moment. We have just had to evacuate our civil defence headquarters.” A 1.9-kilometre (1.2-mile) tunnel linking Christchurch to the nearby port of Lyttleton was closed after cracking appeared, the New Zealand Transport Authority (NZTA) said. “There is some cracking that’s apparent on the surface and there’s apparently some damage to the canopy as well,” NZTA spokesman Andy Knackstedt told national radio. “We don’t know what the extent of that is. They’re in there right now making an assessment.” Mr Parker said the force of the latest convulsion meant there would “inevitably” be more damage to already weakened buildings, adding that the ongoing aftershocks were taking their toll on the city’s residents. “We have got staff in tears, we have got fire engines going through the middle of the city, power is out and a lot of people are very, very churned up by that.” More than 100 aftershocks have rocked the area since Saturday. Officials estimate up to 100,000 homes were damaged in Saturday’s quake, which caused damage estimated at NZ$2 billion (£930 million) but killed no one. – Source

NZ quake caused by unknown faultline
Scientists say that the largest earthquake to hit New Zealand in 80 years was “very unusual” and caused by a newly identified faultline.
by Julian Swallow 9/6/2010

[SOME!] NEW ZEALAND AUTHORITIES BELIEVE the 7.1 magnitude earthquake that struck the South Island city of Christchurch early Saturday was most likely caused by a previously unidentified faultline.

The quake – which was slightly larger than the devastating quake which struck Haiti in January killing over 200,000 people – caused the ground to lift by one to two metres in places, damaging buildings and infrastructure, but only hurting two people.

“In Haiti, the earthquake occurred closer to the populated area and there was a much larger number of people affected. But the most important thing is that New Zealand has a very good building code that they apply very strictly,” says Kevin McCue, director of the Australian Seismological Centre in Canberra. “I attribute [the small amount of damage] to their strong engineering.” – More here
