24. NZMIA > Resources For Schools > Volcanoes > Volcanoes In NZ Provides information on the volcanoes in New Zealand that have erupted in the last few thousand years with information on each. http://www.minerals.co.nz/html/main_topics/resources_for_schools/volcanoes/volca

Volcanoes Over 75 million years ago the New Zealand landmass split away from Australia. Over millions of years the land has been twisted, folded, faulted and shaped. It has been split open by volcanoes, covered under thick layers of ash, and layered with ocean sediment as the sea has alternately risen and fallen. The results of these ancient forces can be seen all around us. The City of Dunedin is built on an ancient volcano that has been extinct for about 10 million years. The hills of Port Chalmers are formed from a long extinct volcano. Auckland city is built on and around a series of volcanic cones. This section covers New Zealand volcanoes which have erupted in the last few thousand years. If you think that just means White Island and Ruapehu you are in for a surprise. Most of the world's volcanoes are located near the boundaries of crustal plates. In New Zealand from White Island to Mount Ruapehu a group of active volcanoes across the North Island marks the zone where the Pacific plate descends into the mantle. The Australian and Pacific plates are constantly moving towards each other at between 40mm to 60mm a year. As surface rocks are carried deeper, they melt in the subsurface heat, forming pockets of molten magma which rise towards the surface. If the magma is rich in silica it is thick and viscous, and the volcanoes it produces are often highly explosive. Violent volcanic eruptions may create huge craters and produce massive flows of incandescent dust and gases which solidify to form ignimbrite. Such rocks cover much of the central North Island. Some explosive volcanoes have blasted out enough volcanic dust to coat the entire country, even as far away as the Chatham Islands.

United States Search and Rescue Task Force Volcanoes Volcanic eruptions are among the Earth's most powerful and destructive forces. Imagine hearing a volcano erupt thousands of miles away. Imagine looking through binoculars and seeing the top of a mountain collapse. Imagine discovering an ancient Roman city that had been buried in volcanic ash. Volcanoes are also creative forces. The Earth's first oceans and atmosphere formed from the gases given off by volcanoes. In turn, oceans and an atmosphere created the environment that made life possible on our planet. Volcanoes have also shaped the Earth's landscape. Many of our mountains, islands, and plains have been built by volcanic eruptions. Why Do Volcanoes Erupt? Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma . Because it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually some of the magma pushes through vents and fissures in the Earth's surface. A volcanic eruption occurs! Magma that has erupted is called lava Some volcanic eruptions are explosive and others are not. How explosive an eruption is depends on how runny or sticky the magma is. If magma is thin and runny, gases can escape easily from it. When this type of magma erupts, it flows out of the volcano. Lava flows rarely kill people, because they move slowly enough for people to get out of their way. Lava flows, however, can cause considerable destruction to buildings in their path.

When pressure from the molten rock beneath the earth's surface becomes too great, the rock, usually accompanied by lava or gases, escapes through a fissure or vent in the crust of the earth. "Volcano" is the term given to both the vent and the conical mountain left by the overflow of the erupted lava, rock and ash. More than 80% of the earth's surface comes from volcanoes. Innumerable volcanic eruptions formed the sea floor and some mountains; gaseous emissions from volcanoes formed the earth's atmosphere. The name "volcano" is said to have come from Vulcano , a volcanic island in the Aeolian Islands of Italy. The name Vulcano originates from Vulcan , a god of fire in Roman mythology. The study of volcanoes is called volcanology (sometimes spelled vulcanology).

Travel agencies This article is a travel topic Volcanoes come in all sorts of shapes and sizes. Although the name evokes images of the conical mountain spewing ash and lava, such events are rare though often newsworthy, and are probably best seen on the TV news rather than witnessed up close and in person. However, many volcanoes around the world are tourist attractions in their own right and are worth a visit, so one can appreciate the awesome power of nature in person. Mts. Bromo and Semeru in action, Java, Indonesia edit Understand Some of the largest volcanoes on earth are not recognisable as such. For example, Yellowstone in the United States Toba in Indonesia , and Taupo in New Zealand are known as super-volcanoes . They are generally in the form of large calderas , which are giant volcanic depressions formed either by large explosive eruptions or quiet long-term drainage of magma, and they often have associated lava flows or domes. Most supervolcanoes are explosive in origin and have undergone unimaginably huge eruptions in the geologic past. However, it is important to note that such volcanoes have erupted violently very infrequently, usually only once every 100,000-800,000 years. Hence, there is no reason to worry that Yellowstone, for example, will explode within your lifetime! Many are so big that, for many years, geologists did not appreciate that these features were volcanoes in their own rights. Compared to these, the currently active volcanoes on earth are relatively quite small!

Volcanoes vary quite a bit in their structure - some are cracks in the earth's crust where lava erupts, and some are domes, shields, or mountain-like structures with a crater at the summit. Magma is molten rock within the Earth's crust. When magma erupts through the earth's surface it is called lava . Lava can be thick and slow-moving or thin and fast-moving.

VOLCANOES Mayon Volcano, a beautifully symmetrical but dangerous composite volcano on Luzon Island, Philippines. A volcano is a mound, hill or mountain constructed by solid fragments, lava flows, and or dome-like extrusions deposited around a vent from which the material is extruded. The vent is a conduit that extends from the earth's upper mantle or lithosphere to the surface. Most of the material is deposited close to the vent, but some is carried high into the atmosphere to be spread by winds hundreds or thousands of kilometers from the source. Types of Volcanoes The form, or shape, of a volcano is governed by the composition of erupting magma and type of erupted products (volcaniclastic products of various kinds such as pyroclastic and autoclastic fragments; or effusive lava). Their shapes are determined in large part by the explosivity of eruptions, and volume of water that interacts with magma. Shield Volcanoes View northward toward Mauna Loa volcano from Pohue Bay, south coast of Hawaii. The broad curving horizon line is the summit of Mauna Loa that stands over 14,000 feet above sea level and 30,000 feet above the sea floor. It is the highest mountain on earth. Shield volcanoes are large volcanoes with broad summit areas and low-sloping sides (shield shape) because the extruded products are mainly low viscosity basaltic lava flows. A good example of a shield volcano is the Island of Hawaii (the "Big Island"). The Big Island is formed of five coalesced volcanoes of successively younger ages, the older ones apparently extinct. Mauna Loa, one of the main volcanoes, has a higher elevation than any mountain on earth 9090 meters (30,000 feet) from the floor of the ocean to its highest peak.

Volcanoes and Society Sarah Getsinger and Erin Nalepa INTRODUCTION Volcanoes are explosive things of beauty that can tell us much about our past, and that have an impact on our futures. Like humans, sometimes they are passive and unnoticeable, appreciated for their history and geological importance, sometimes aggressive, angry, and very active. By exploring the science behind the formation and activity of volcanoes, and discussing the impact volcanoes have on today's society, we can value their importance at a higher level. A volcanic event occurs when there is a sudden or continuing release of energy caused by near surface, or surface magma movement. The energy release can occur in the form of earthquakes, gas-emission at the surface, release of heat, explosive release of gases, and the non-explosive extrusion of magma. An event could be destructive without the release of solids or magmatic fluid, or be destructive with voluminous lava flows or explosive activity. WHY? WHAT? figure 2 Shield volcanoes have broad summit areas because of these flows, and are some of the largest volcanoes.
