Australian Disasters There have been many natural and man-made disasters in Australia. This country of contrasts regularly suffers floods, cyclones, bush fires, drought, earthquakes, earth tremors and landslides. Major disasters have included: Cyclone Tracy - which devastated Darwin on the night of Christmas Eve 1974. Ash Wednesday Bush Fires - when around 180 bushfires broke out on 16 February 1983, devastating the Adelaide hills. Newcastle Earthquake - 28th December, 1989. The Newcastle earthquake, the first fatal one in Australia, claimed 13 lives. The devastation to buildings and other structures was extensive. Shipwrecks: 1999 Pandora Chronicle - the Port of Townsville expedition to the wreck of the infamous Pandora Hurricane Elena Photo from the NASA Photo Gallery Natural Disasters Natural disasters can arise from: Weather patterns eg storms, cyclones, hurricanes, floods, tornadoes Other climatic conditions eg droughts, bush fires, avalanches Changes in the earth's crust eg volcanoes, earthquakes, tsunami or tidal waves Follow the links below to find out more.

Link to Teacher Page by Maria Gomez Introduction Task Resources Process ... Conclusion Introduction Have you ever seen a volcano erupt? Do you know the location of any volcanoes? Do you know how to make a volcano? Join me for a fun volcanic experience!! The Task Can you answer the following questions?: What is a volcano? When and how do they erupt? Where are the active and inactive volcanoes located? How do I build a model volcano? Resources Volcano World Volcanology Projects Kids Door The Process Find a partner to work with. Print out or obtain a sheet of the questions from your teacher or print them from this page. Explore the sites under resources and search for the answers. When you have completed researching all 4 questions, pick one volcano and report to the class your findings. As a final project you and your partner will click on projects and choose one of the volcanoes to build. Evaluation When you have completed all research, your report, and the final project, your peers will complete a rubric on your findings. Conclusion Although volcanoes are commonly considered natural disasters, they are bearers of new life. It is important to understand that we may not be able to prevent volcanic eruptions, we can study and learn from them in order to detect any future eruptions.

Earth's Untamed Energy: Earthquakes and Volcanoes In this lecture, we learn: What is the difference between the intensity and the magnitude of an earthquake? What are seismic waves and what information do they give us about earthquakes when they have been recorded by a seismograph? How does temperature change with increasing depth in the Earth? What are the mechanisms by which magma is formed? What types of material are ejected by volcanoes? Jump to: [ Earthquakes Intensity Earthquake Location and Magnitude Energy ... Format for printing Natural Hazards It hardly needs to be said that natural hazards have devastating effects on society. The death and destruction associated with earthquakes, volcanoes, tsunamis (tidal waves), hurricanes and other natural phenomena is unbelievably large. Beside the tragedy of loss of human life, natural hazards increasingly take their toll on the economies of nations. Take the US, for example, where one or more natural phenomena always threaten. Life in California occurs in the shadow of major earthquake threats. Activity along the San Andreas Fault, which passes through several major cosmopolitan areas, is a classic example. Elsewhere along the Pacific coast of the US, volcanic activity is an additional threat. The eruption of Mt. St Helen's in Washington State occurred in an isolated area, with relatively minor loss of human life. An eruption of Mt Rainier, on the other hand, poses a major threat. Along the East coast, the on-land arrival of hurricanes devastates coastal areas, including cities. Even the relatively quiescent interior regions of the US have their share of problems. Tornadoes appear unexpectedly and work their terror quickly, while flooding of major river systems occurs on a regular basis. A nice website by

29. Disasters And Hazard Mitigation - Hot Heads Hot Heads. Volcanoes are close cousins of earthquakes, arising as theydo from the same powerful motions of the planet s tectonic plates. http://www.nsf.gov/od/lpa/news/publicat/nsf0050/mitigation/hotheads.htm

Hot Heads Volcanoes are close cousins of earthquakes, arising as they do from the same powerful motions of the planet's tectonic plates. Despite their fiery reputation for chaos and destruction, however, only about sixty volcanoes erupt each year. What's more, most volcanoes are on the ocean floor where plate boundaries are converging or spreading over "hot spots"—large subterranean pools of magma. This is not to say that volcanoes pose no peril. Over the last 300 years more than 260,000 people have died from volcanic activity. The 1991 eruption of the Philippines' Mount Pinatubo killed more than 300 people and devastated the area's economy. When Mount St. Helen's blew its stack in the State of Washington in 1980, 57 people died, nearly 7,000 big game animals were killed, more than 12 million salmon perished, forests were devastated, and the economy took a nearly $1 billion hit. All of this reinforces the need for better ways to model and predict volcanic activity. One way to both study and monitor a volcano is to place a gas sensing device called COSPEC along the volcano's flanks. COSPEC (for "correlation spectrometer") measures how much sulfur dioxide gas is escaping from the volcano's interior. A jump in the amount of sulfur dioxide suggests an imminent eruption. Still, a few hours' or, at most, a few days' warning is the best that scientists can manage with current knowledge and technology. And sometimes, of course, there is no discernible warning at all.

NEW HIGH SCHOOL IN THE CITY OF ORTING? This example lesson is made with use of http://cotf.edu/ETE/scen/volcanoes/vmodulep1.html Goal: (note: text from the external link mentioned above, with some modifications) The students have to make a decision based on several sorts of information: geographic, personal, social, pictures, etc. The students have to work together and make a decision together; they should work collaborative. Introduction: As an introduction, you can ask the students if they want to live somewhere where the chance on an earthquake or a volcano-eruption is high. You'll probably get a discussion on that (maybe you live in such a risk area?). Confront the students with the problem of Orting. Let them work through the information in pairs or groups. The Problem: Business and community leaders in the city of Orting in Pierce County, Washington State, wish to build a new high school to accommodate and encourage the local explosion of suburban population. However, Pierce County officials have refused permission to build the high school on county lands because they feel the location is hazardous. Geological surveys show that both Orting and the proposed high school site are on top of solidified mud flows that originated on the slopes of nearby Mount Rainier. Based on the location of older flows around Mount Rainier and on experience gained from observing mud flows during the 1980 eruption of Mount St. Helens, county officials argue that any new mud flow coming down the valley could easily destroy the high school and anybody that happened to be in it. The city has tried three times to pass a bond issue enabling the high school to be built on city lands, but so far without success.

Homepage Swiss Projects Echanges Universitaires News ... Links Programme de bourses "Echanges Universitaires" Natural disasters in Cameroon Volcanoes In the night of August 21, 1986 1746 people and a large number of animals died of suffocation from CO rich gases emitted from a volcanic maar, lake Nyos in NW-Cameroon (Figures 1 to 3). The gas burst occurred asymmetrically, uprooting the trees at the southern end of the lake approx. 30 m above water level. Animal cadavers were found to an elevation of 150 m above the lake. Volcanic eruptions bring gas up from the interior of the earth crust and from the upper mantle. Primitive, alkaline magmas of basanitic, ankaramitic and basaltic composition are often accompanied by large amounts of volatiles, particularly of CO , H and CH . The origin of CO in the magma reservoirs and in the hydrothermal systems is rather complex. We favour the hypothesis of mantle origin by the reaction: CH + 2 H O = 2 CO + 4 H O. The production of CO runs parallel with the generation of primitive alkaline melts by partial melting from a lherzolitic mantle source. In Lake Nyos, the sediments together with a fault system at the southern end of the lake as well as the water itself seem to have acted as a gas trap. A minor earthquake, internal CO
