PLANETARY TREMORS: - 6.3 MAGNITUDE EARTHQUAKE SHAKES TOKOROA, NEW ZEALAND!
December 07, 2012 - TOKOROA, NEW ZEALAND -
As if the world has not shaken enough. New Zealand falls victim to Friday’s onslaught of earthquakes throughout the globe. A strong Magnitude 6.3 earthquake jolts residents of Tokoroa, New Zealand. The quake hit 19km SE of Tokoroa.
On December 22nd of last year a series of strong earthquakes struck the New Zealand city of Christchurch. It too was on a Friday although it is Saturday presently in that country. Last years quake rattled buildings, sending goods tumbling from shelves and prompting terrified holiday shoppers to flee into the streets. There was no tsunami alert issued and the city appeared to have been spared major damage.
Again speaking of last year’s tremor, the first 5.8-magnitude quake struck on a Friday afternoon, 16 miles (26 kilometers) north of Christchurch and 2.5 miles (4 kilometers) deep, the U.S. Geological Survey said. Minutes later, a 5.3-magnitude aftershock hit. About an hour after that, the city was shaken by another 5.8-magnitude temblor, the U.S.G.S. said, though New Zealand’s geological agency GNS Science recorded that aftershock as a magnitude-6.0. Both aftershocks were less than 3 miles (5 kilometers) deep. New Zealand is part of the Pacific Ring of Fire, which is geologically active. No damage has been reported as the seismic event just occurred 10 minutes ago. As soon as we have word of news from that area in the world we will provide an immediate report. - The Guardian Express.
Seismotectonics of the Eastern Margin of the Australia Plate.
The eastern margin of the Australia plate is one of the most sesimically active areas of the world due to high rates of convergence between the Australia and Pacific plates. In the region of New Zealand, the 3000 km long Australia-Pacific plate boundary extends from south of Macquarie Island to the southern Kermadec Island chain. It includes an oceanic transform (the Macquarie Ridge), two oppositely verging subduction zones (Puysegur and Hikurangi), and a transpressive continental transform, the Alpine Fault through South Island, New Zealand. Since 1900 there have been 15 M7.5+ earthquakes recorded near New Zealand. Nine of these, and the four largest, occurred along or near the Macquarie Ridge, including the 1989 M8.2 event on the ridge itself, and the 2004 M8.1 event 200 km to the west of the plate boundary, reflecting intraplate deformation. The largest recorded earthquake in New Zealand itself was the 1931 M7.8 Hawke's Bay earthquake, which killed 256 people. The last M7.5+ earthquake along the Alpine Fault was 170 years ago; studies of the faults' strain accumulation suggest that similar events are likely to occur again.

According to the U.S. Geological Survey (USGS) there are literally thousands of earthquake events around the world in any given year. Most of these quakes are minor tremors that are seemingly insignificant and pose no danger to life or property. Although these events are monitored and tracked as potential warning signs of much larger quakes, they are not prominently displayed on the USGS website.
The USGS website does however keep a running list of what they consider “Significant Earthquake”. This list is made up of quake activity that measures 3.0 or higher on the Richter magnitude scale. After an evaluation of these earthquake statistics, the results are somewhat startling.
In the year 2008, there were 58 significant earthquake events around the world. Conservatively considering that a 7.0 magnitude or higher quake could dramatically effect human life, 12 of the 2008 events were at or above 7.0.
In 2009, there were 72 quakes classified as significant with 17 measuring 7.0 or higher.
Although the number of significant earthquake events decreased to 68 in 2010, the number of 7.0 or higher magnitude quakes increased to 22.
Less then three months into the year 2011, we have already seen 18 significant earthquake events. Of that 18 and including the recent earthquake in Japan, 6 have been classified as 7.0 or higher.
Although there has been an obvious increase in the number of 7.0+ magnitude earthquakes over the last three years, the steady increase in the intensity of 8.0 or higher quakes and the effects they are having on the earth is even more frightening.
In September 2009 there was an 8.1 magnitude earthquake in the Samoa Islands. In February 2010 Chile experienced an 8.8, and the March 2011 earthquake in Japan had a magnitude of 8.9 which was determined to be the largest quake in Japan’s recorded history, and the 7th largest in recorded world history.
The dramatic increase in intensity of these last three 8.0+ quakes has not only proven to be the most devastating in terms of loss in life and property, but has literally shifted the earth’s axis. If statistics are any indication, we can be assured that the next 9.0 or higher earthquake is just around the corner, and all signs point to the United States as the next target.
It’s not a matter of “if” anymore, it’s now a matter of “when”.
