  • + 6 Natural Hazards  Definition  Naturally occurring event that threatens human lives and causes damage to property  Tectonic Natural Hazard  Caused by plate movements when continental crusts and ocean floors move  Eg. Earthquakes, volcanic eruptions and tsunamis  Climate Related Natural Hazard  Caused by severe and extreme weather and climate conditions  Eg. Drought, tropical cyclones and floodsarmanalluwie.blogspot.com

  • + 8 Recall: Natural Hazards  Definition?  Naturally occurring event that threatens human lives and causes damage to property  Tectonic Natural Hazard  Eg. Earthquakes, volcanic eruptions and tsunamis  Climate Related Natural Hazard  Eg. Drought, tropical cyclones and floods Distribute Handout 2armanalluwie.blogspot.com
  • + 9 Let’s test it out  Classify the following hazards into climate or tectonic hazard  Describe the impact of each hazard Distribute Handout 2armanalluwie.blogspot.com
  • + 10 Gas Emissions at Volcan Copahue http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=80095armanalluwie.blogspot.com
  • + 11 Gas Emissions at Volcan Copahue The Chilean National Service of Geology and Mining, reported that the eruption was likely caused by water vaporizing as it interacted with magma rising inside the volcano. Since then, intermittent steam and gas plumes, accompanied by continuing earthquakes was observed. The earthquakes suggest that magma is fracturing rock as it rises from beneath the volcano. Volcán Copahue is a composite volcano located in the Andes, on the border of Chile and Argentina. This natural-color satellite image shows a blue-tinted gas plume streaming toward the east. The nearest settlement is Caviahue, an Argentinian ski resort.armanalluwie.blogspot.com
  • + 12 Tropical Cyclone Dumile http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=80074armanalluwie.blogspot.com
  • + 13 Tropical Cyclone Dumile Tropical Storm Dumile formed at the beginning of 2013 in the Indian Ocean, east of Madagascar. The storm moved southward as it strengthened into a tropical cyclone. On January 3, 2013, the U.S. Navy’s Joint Typhoon Warning Center (JTWC) reported that Dumile had maximum sustained winds of 120 kilometers per hour and gusts up to 150 kilometers per hour. Dumile’s clouds extended over the islands of Réunion and Mauritius but stopped short of Madagascar’s capital city of Antananarivo.armanalluwie.blogspot.com
  • + 14 Wildfires in Tasmaniaarmanalluwie.blogspot.com
  • + 15 Wildfires in Tasmania In January 2013, intense bushfires blazed in Tasmania, an island south of Australia. NASA’s Terra satellite captured this image showing numbers of fires burning across the island on January 7, 2013. Red outlines indicate hot spots where satellites detected unusually warm surface temperatures associated with fires. Extreme heat and strong winds fueled the fires. Temperatures in Hobart, the capital of Tasmania, soared to a record high of 41.8°Celsius (107.2°Fahrenheit) on January 4. The blazes destroyed more than 100 homes, including many in the small community of Dunalley. More than 100 people were missing after fire tore through the town.armanalluwie.blogspot.com
  • + 16 Storm turns the Taklimakan Desert white http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=80058armanalluwie.blogspot.com
  • + 17 Storm turns the Taklimakan Desert white Snow-covered deserts are rare, but that’s exactly what NASA’s Aqua satellite observed as it passed over the Taklimakan Desert in western China on January 2, 2013. Snow has covered much of the desert since a storm blew through the area on December 26. The Taklimakan is one of the world’s largest—and hottest— sandy deserts. Water flowing into the Tarim Basin has no outlet, so over the years, sediments have steadily accumulated. In parts of the desert, sand can pile up to 300 meters (roughly 1,000 feet) high. The mountains that enclose the sea of sand— the Tien Shan in the north and the Kunlun Shan in the south— were also covered with what appeared to be a significantly thicker layer of snow in January 2013.armanalluwie.blogspot.com
