Older construction, not necessarily. Effects and responses of earthquakes Effects. Thanks for the insights on the ChCh NZ building situation. Earthquakes and volcanoes occur in the same places because they both happen along the Ring of Fire. The most intense earthquake activity is where subduction is taking place, but there is some earthquake activity along the mid-ocean ridges and above mantle ‘hot-spots’ 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. Dams Projects Reports. 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. Note that the relative movement of the plates, indicated by the arrow, is as described, with one plate grinding past the other. The energy spreads outward in waves, which shake the Earth. These earthquakes are usually too weak to be felt but can be detected and recorded by sensitive instruments. … This pattern is part of the ‘Ring of Fire’, the almost continuous belt of volcanoes and earthquakes rimming the Pacific Ocean. Volcano. New Zealands volcanoes are located on North Island mostly within the Taupo Volcanic Zone. This type of volcano is called a cone volcano. There was quite a lot of chatter after the last Chch quake about them, and how many lives they had probably saved. -Johannes Kepler They can destroy buildings and infrastructure, with devastating and deadly effects. During this time, what was to become New Zealand separated from what is now Australia. Read this ScienceStruck article to learn more about the relationship between these two natural processes. On the upper right is the California coast. Gauges Historical Events. Wouldn't you?? That island state consists of a series of volcanoes coming up from the middle of a plate, but not on a continental mass. Thick lava flows down the sides of the mountain and builds up steep sides. The most powerful event registered as … 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 Pacific Ring of Fire is aptly named. As the brittle crust gives way under the pressure, a fault ruptures and an earthquake is unleashed. Most events occur along the main ranges running from Fiordland in the southwest to East Cape in the northeast. 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.. Earthquakes and volcanoes occur in New Zealand because it lies on a tectonic plate boundary between the Pacific Plate and the Indo Australian Plate as is shown in Figure 1. Tsunami. Maybe it is time to rename the town to Nochurch. Well, both. Auckland, New Zealand, is home to around 50 dormant volcanoes. 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. 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. Their GeoNet Project uses special equipment to observe and monitor the land. DD. Then the magma squirts into the crack and starts building pressure again. The energy is released. In New Zealand, volcanoes and earthquakes are related in that they are both caused by the tectonic plates our country sits on. To the lower left, also circled in green, is New Zealand. Volcano Level Volcanic Activity Ruapehu 2 Moderate to heightened volcanic unrest. Earthquakes 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. 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. Privacy statement. “When these super volcanoes erupted, they caused earthquakes, tsunamis, blew away mountains and covered continents in hot lava. Every time the rock cracks it makes a small earthquake. According to the GeoNet archives New Zealand has experienced 296 earthquakes of 3.0 magnitude or greater over the last 30 days. We live in a very exciting country. On the TV this morning, the mayor of Christchurch told his story: Having just left a series of meetings, he was sitting on a balcony outside the city offices in a tall building with his executive assistant planning their next activities when the quake struck. (Synopsis), The Nanostructure of Noms: Why Edible Fats Are So Tasty, 5 Vital Lessons Scientists Learn That Can Better Everyone's Life (Synopsis). White Island is our most continually active volcano. The occasional GNS scientists who are making statements on local TV are also pointing out that soil-surface acceleration in this quake was approximately twice as high as in the 7.1 quake in September. This recent activity is primarily due to the country's position on the boundary between the … Sometimes the pressure of magma forcing its way through to the Earth’s surface will trigger earthquake activity. Why Haven't Crocodiles Evolved Much Since The Age Of The Dinosaurs? It says a lot in an image. Other 'supervolcanoes' would likely include the large caldera volcanoes of Japan, Indonesia, Alaska (e.g. In the future I will be blogging at Greg Laden's blog, located at its original home at gregladen.com. 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. 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. But this complexity can be characterized in a rather simple way that probably describes the geology of New Zealand quite accurately: Modern New Zealand is the froth that forms on the surface of the earth over a subduction zone, where one continental plate is diving under another. Yet going back even…, X-ray diffraction patterns reveal the orientation of fat crystals. When the powerful earthquake stopped, he picked himself up off the floor of the balcony and gazed across his city to see absolute devastation including numerous collapsed buildings and destroyed infrastructure. Cayhina232000, Hope friends or family in Christchurch are all right. We are part of Science 2.0, a science education nonprofit operating under Section 501(c)(3) of the Internal Revenue Code. Ðnly amphibious military hovercraft can travel on the destroyed roads and deliver food and medicines and to evacuate large groups of people. I may be repeating, but there are several things to remember: - Christchurch (abbreviated Chch by locals) has had several quakes over the past 6 months, including 7.1 (Sep 4) and 5.1 (Boxing Day, close to city and shallow) among others. They look like an upside down ice cream cone with smoke coming from the peak. GNS scientists gather this information to learn about our shaky country so they can warn us and try and reduce the risk of harm. The plates slowly move and push against each other. During the same period, an equivalent size area that includes one of the more earthquake prone states in the US, California, had 22 magnitude 3.0 or higher events (Data from the USGS).
