This is a wonderfully free country to live in. Around 100 to 150 are big enough for us to feel. Clearly, earthquakes require the existence of a higher being as explanation, so if New Zealand has a lot of them, they obviously pray to the wrong god. Earthquakes and volcanoes are natural phenomena resulting from the plate tectonics. What do you think? Home; Earthquake. Also shown are active volcanoes. It's a case of the data presented one way telling it's own story. The not so good news is that we also get shaky ground in the form of earthquakes and, less often, volcanic eruptions. I too am an atheist. We know of super volcano eruptions that blew so much ash and gasses into the atmosphere, that global climate changed dramatically. Greg, You should be able to locate an USGS Pacific map featuring the "ring of fire" as it's nicknamed showing the earthquakes. The same thing happens with the tectonic plates. Based on what I see in your blog, similar problems are occurring as happened in New York on 9/11 with cell phones and such. New Zealand sits on the edges of two tectonic plates – the Australian and the Pacific plates.

Thick lava flows down the sides of the mountain and builds up steep sides. Some older buildings (from some time ago) were pulled down as the cost of strengthening didn't figure well with the cost of replacing -at least this is my understanding. The only effective way of detecting people under the rubble - it's infrared camera of a military helicopter. The map below shows the main plates. Earthquakes represent the release of that energy. The plate on top of this unholy geological intercourse is forced upwards, forming mountains, and the whole process is highly energetic and causes frequent earthquakes, which can be quite severe. Well, the "ring of fire" is more or less the edge of the huge Pacific plate (made up of smaller plates), plus/minus, as shown in the diagram above. Q.E.D. It has a long (half a billion years) geological history consisting of volcanism, uplift, subduction (the opposite of uplift) followed by the formation of sediments, more uplift, and so on. Maybe it is time to rename the town to Nochurch. But scientists say a volcano is an opening in the Earth’s crust in which lava, steam, gases or ash is ejected. The Sep 4th event was a good 30-40 km outside the centre; this is only 10 km from the centre and shallower, centred in/near Lyttelton, the port village south of the town. Read on to find out how New Zealand deals with earthquake hazards and the problems that being a shaky nation brings. But it is a little more complicated than that. The following drawing represents a schematic east-west cross section through New Zealand: The green curve on the right is the sea floor of the Pacific Plate diving beneath the part of the Australian plate that carries much of New Zealand. Note that the relative movement of the plates, indicated by the arrow, is as described, with one plate grinding past the other. That island state consists of a series of volcanoes coming up from the middle of a plate, but not on a continental mass. They are found both on land and sea. I don't believe in god but there is a hire power but it not from this earth. The distribution and directionality of these crystal nanostructures (parallel to the shear field in C, randomly arranged in D) affects the flavor and texture of foods.

William Wehrum is a lawyer and once, apparently, worked for the EPA. Very interesting post, you just taught me quite a lot about a country I've lived in all my life! Trump is trying to appoint him to be assistant administrator for air and radiation.

Their GeoNet Project uses special equipment to observe and monitor the land. - The recent event is much closer and shallower. But after Monday's fatal eruption, some question whether they should have been there at all. Volcanoes and earthquakes are often found in the same place, but are they related? New Zealand has different types of volcanoes. But not always - a new study suggests that many of these tremors aren't warnings, but aftershocks. It's a string of volcanoes in the Pacific Ocean, and the region is prone to earthquakes. The telecomm people then try to bring in generators to cover them until the power is back up. We think about a lone genius, working outside the constraints of mainstream academia or mainstream thinking, working on something no one else works on. New Zealand's Earthquake Commission and Geological Survey (GeoNet) reported a magnitude 4.2 quake in New Zealand near Upper Hutt, Upper Hutt City, Wellington, only 5 minutes ago. (Hawaii) It is still an Island !! I don't care how large an island seems to be when you are standing in the middle of it..ex. They push or scrape against each other until something has to give – and boom! The volcanism of New Zealand has been responsible for many of the country's geographical features, especially in the North Island and the country's outlying islands. Italy truly deserves to be called "the Cradle of Volcanology" - not only because it hosts virtually all existing types of volcanoes and volcanic rock compositions, and seven of its volcanoes…, Mid-continent earthquakes are often aftershocks of centuries-old tremors, A volcanic cruise through the Mariana Islands: Part 1, Etna Week (Part 1) - Brief Anatomy of an Exceptional Volcano, http://all-geo.org/highlyallochthonous/2011/02/magnitude-6-3-earthquake…, http://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=10708582.

Watch: While the land's volcanism dates back to before the Zealandia microcontinent rifted away from Gondwana 60–130 million years ago, activity continues today with minor eruptions occurring every few years. I'm not a geologist, but you'd think that all other thing being equal the force would dissipate with the inverse square of the distance from the focal point, so the location & distance would matter. The most powerful event registered as … Much of the rock that makes up New Zealand is from the edge of that ancient continent, and uplift and subduction occurred several times because of the relative movement of the plates.
