suggest why both volcanoes and earthquakes occur in new zealand

Both New Zealand and California sit on the edge of the Pacific Plate, but in very different places and on very different types of plate boundaries. If you brace your shoulder against someone else’s shoulder and push, the energy is stored up until one of you is pushed aside. Dams Projects Reports. Like earthquake activity, volcanoes in New Zealand usually occur along the plate boundary. Earthquakes tend to be concentrated at the edges of tectonic plates, as these areas build up energy as plates move in relation to each other. (Not an expert, just what I've picked up; it's the second time around on this for Chch. New evidence of a 19th century earthquake on New Zealand's Alpine fault suggests that in at least one portion of the fault, smaller earthquakes may occur in between such large rupture events. Q.E.D. Volcano. You'd have to see to get what I mean. Volcanoes and earthquakes typically occur where plates meet. As others have said, the building standards in NZ are very high with specific earthquake-related elements. 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. quibblista: Interesting. The good news is that we get to enjoy rugged mountains for skiing and tramping and thermal spots for warm swims. The exact magnitude, epicenter, and depth of the quake might be revised within the next few … But scientists say a volcano is an opening in the Earth’s crust in which lava, steam, gases or ash is ejected. This type of volcano is called a cone volcano. New Zealand records 14,000–15,000 earthquakes every year. and discussion of seismic lensing off the basalt of the Port Hills here: http://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=10708579, Hello from the States. It's a string of volcanoes in the Pacific Ocean, and the region is prone to earthquakes. If you think we are the only one in this big space of the galaxy or universe your just stupid and you have a shallow mind. William Wehrum is a lawyer and once, apparently, worked for the EPA. New Zealand has so many earthquakes and volcanoes because it is in the wrong place (at the juncture of two tectonic plates) at the wrong time (while one plate is diving beneath the other). But what is New Zealand? I often wonder over the millenia how many Islands that at one time were huge and habitable are now hidden under the waves somewhere. Pretty much everything stayed standing during that one and there was no loss of life, but I think the buildings were just too weak to survive another large earthquake so close to the surface. This is a reasonably important job that concerns many aspects of the environment. https://www.sciencelearn.org.nz/resources/930-earthquakes-and-volcanoes Read on to find out how New Zealand deals with earthquake hazards and the problems that being a shaky nation brings. Our extremes are due to where our country sits. I getting the impression the liquefaction occurred in areas it didn't before (?). New Zealand was once dubbed The Shaky Isles due to it being one of the most seismically active countries in the world. In San Francisco, many important buildings have been retrofit to meet current earthquake codes (among them Brooks Hall in the Civic Center, which ironically was the venue for meetings of the world's foremost association of earthquake experts, the American Geophysical Union, in the years prior to its temporary closure for such a retrofit). Read on to find out how New Zealand deals with earthquake hazards and the problems that being a shaky nation brings. That island state consists of a series of volcanoes coming up from the middle of a plate, but not on a continental mass. re: the ring of fire, what I meant is that their (USGS) maps of all the (larger) quakes mapped onto the Pacific region is quite impressive. The telecomm people then try to bring in generators to cover them until the power is back up. Is it a thrust fault? The effects of an earthquake can vary depending on: Fortunately, it mostly releases gases and steam. Contributions are fully tax-deductible. The energy spreads outward in waves, which shake the Earth. Maybe it is time to rename the town to Nochurch. Please make a tax-deductible donation if you value independent science communication, collaboration, participation, and open access. Invoking the Racketeer Influenced and Corrupt Organizations Act, or RICO, a federal conspiracy law devised to ensnare mobsters, the suit accuses the organizations, as well as several green campaigners…. Note here that the pacific plate is moving northwest, and the Australian plate is moving (actually, spreading) southeast, the two plates slamming into each other. Earthquakes represent the release of that energy. 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. That’s just a blink of an eye in geologic terms. As the geologists investigate the earthquake details are emerging for why it has been so devastating. But that is nothing compared to what happens to New Zealand as well as Japan and several other places. The facts and evidence from the natural enviroment on why the earth behaves as it does (eg earthquakes, volcanoes and other geological and meteorological activity) and the animals (of which we are selves are) and plants are the way they are, is far more interesting and wholely believable; than saying it is a punishment from some mythological being that does not exist. In the area of voting, the main problem seems to be the expenditure of great amounts of outrage and…, ... which I've posted on before ... there are new developments, summarized at Inside Climate News: Mount Etna - Brief Anatomy of an Exceptional Volcano Earthquakes in New Zealand occur because we are located on the boundary of two of the world’s major tectonic plates – the Pacific Plate and the Australian Plate. We know of super volcano eruptions that blew so much ash and gasses into the atmosphere, that global climate changed dramatically. The plates are also responsible for the thousands of earthquakes we have every year. Then, starting about 24 million years ago, the Australian plate (still spreading) and the Pacific plate started to interact more energetically, both moving towards each other and rinding past each other, causing the formation of the massive mountain ridges seen today in New Zealand, as well as a great deal of volcanic activity. I have relatives in Seattle, which is susceptible to similar earthquakes (the Juan de Fuca plate is diving under the North American plate along the Cascadian coast, hence the earthquakes and volcanoes in the region)--older parts of the city were built before the extent of vulnerability to earthquakes was known. New Zealand is a new island nation. As subduction happens, interesting things happen that cause the formation of lava (in red) along the margins of the plates, which moves upwards pushing through and expanding the cracks that inevitably form when continents are mushing together, often forming pools of lava much nearer the surface as well. FAQ Glossary How Videos. The magma exerts pressure on the rocks until it cracks the rock. What do you think? Wikipedia is fake and elora needs to realise that!!!!!!!!!!!!!!!! Ed was in the Coast…, Etna Week Part 1 In New Zealand, volcanoes and earthquakes are related in that they are both caused by the tectonic plates our country sits on. I too am an atheist. Re: cell phones. GeoNet is New Zealand’s official source of earthquakes and volcanic alerts. I have a feeling that Scienceblogs will not last long without me. Its land isn’t even 10,000 years old yet! Before discussing the relationship between earthquakes and volcanoes, let’s take a brief look at each of them individually. They are found both on land and sea. Whakaari/White Island 1 Minor volcanic unrest. As explained on CNN International this morning, Christ Church is especially vulnerable to quake damage because it is built on top of mostly sand. Earthquakes and volcanoes are natural phenomena resulting from the plate tectonics. The Christchurch quake, scientists say, was meanwhile part of the same spate that had seen thousands of quakes triggered by the 7.1 earthquake which … But it is a little more complicated than that. I'm sure Pat Robertson will set us straight on why these earthquakes happened. https://twitter.com/SenJeffMerkley/status/…, “Light thinks it travels faster than anything but it is wrong.

As is my husband, and a large number of my friends. The earthquake hit early morning on Saturday 2 January 2021 at 4:57 am local time at a shallow depth of 24 km. © 2006-2020 Science 2.0. New Zealand is Middle Earth, and Sauron is on the move. Is it an oceanic island? When that occurs there are two major effects that may occur: One of the plates dives under the other (subduction) and the other buckles, forming mountains. Eric, the older buildings would have been strengthened (or should have) - it's a requirement. This is pretty energetic and can create substantial movements of earth, very large and complex fault systems, and plenty of earthquakes. On the upper right is the California coast. It would be nice to that relected in the Census figures and the local skeptics have been pusing the 'if you don't beleive, don't tick the box' message. “When these super volcanoes erupted, they caused earthquakes, tsunamis, blew away mountains and covered continents in hot lava. If you want, you can imagine back in the Universe to a time before it looked anything like ours did. Note that the relative movement of the plates, indicated by the arrow, is as described, with one plate grinding past the other. This creates a zone of subduction where the plate melts. New Zealand has so many earthquakes and volcanoes because it is in the wrong place (at the juncture of two tectonic plates) at the wrong time (while one plate is diving beneath the other). Volcano Level Volcanic Activity Ruapehu 2 Moderate to heightened volcanic unrest. These pools ... those at the subduction juncture itself and those formed secondarily higher up ... are the source of lava for numerous volcanoes. Though in saying that, and despite the fact I am an atheist myself, if believing in a mythical being or beings brings people comfort and hope in a time of disaster such as the aftermath of an earthquake, than they should be free to have the belief and no one should tell them it is wrong. For example, when Tarawera erupted in 1886, more than 30 earthquakes were felt in the Rotorua region just before the eruption. This is a wonderfully free country to live in.
