Sw3 week12 2

  1. 1. Earthquake in NewZealand and Tsunami warning SW3
  2. 2. Geography of New Zealand The area of New Zealand is 268,680 square kilometers. In New Zealand, there are main two islands of North island and South island and alot of small islands. There is capital Wellington in North island. Moreover, Auckland that is the maximum city in this country is commerce and an economic heartland. The precipitation day is 100 days or more a year, and moist towns. North island doesnt have a mountain range as steep as South island.
  3. 3. However, the volcanic activity is active. The highest peak in North island is Mount Ruapehu of 2,797 m. South island is the big island of the land area. Inthe central city, there is Christchurch. The South Alps mountain range that is called "Alps mountain range in the southern hemisphere" soars at the center of the island. The highest peak is Mt. Cook of 3,754m. Mine of 3,000m or more is additionally and there are 18. Rich nature like other Tasman Glacier, theSouthern Alps, Mt. Cook, and the Milford sounds, etc. is famous. Queenstown is famous sightseeing and a resort district in worldwide. The hot spring is scattered in various places, too.
  4. 4. Earthquake in New Zealand Earthquake happened in New Zealand. An earthquake measuring 7.6 on the Richter scale jolted the KermadecIslands region of New Zealand at 1903 GMT on Wednesday,the U.S. Geological Survey said. The quake was centered 161 km east of Raoul Island of the Kermadec Islands, which is some 920 km south of Tonga. The epicenter was at a depth of 20 km.  No damages have been reported so far. The U.S. Pacific Tsunami Warning Center has issued a non- expanding regional tsunami warning for the Kermadec Islands, New Zealand and the Pacific nation of Tonga.
  5. 5. New Zealands Civil Defense has issued a tsunamiwarning for New Zealands Northland, Bay of Plenty, East Coast and Hawkes Bay. The National Crisis Management Center has been activated and Civil Defense said the first wave to arrive will reach NewZealand at 8.52 a.m. on Thursday. Civil Defense saidpeople in coastal areas should stay off the beaches,stay out of the water and not go sightseeing. A waveof between 60 cm and 1 meter have been detected atRaoul Island. Civil Defense said it is not expecting awall of water but is concerned about strong currents in coastal areas.
  6. 6. Tsunami warning In this case, Tsunami was happened by earth quake. And then, Tsunami warning systemfunctioned. A Tsunami warning system is a system to detect tsunamis and issue warnings to prevent lossof life and property, whose roots extend back into the 1920s. It consists of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely alarms to permit evacuation of coastal areas.
  7. 7. There are two distinct types of tsunami warning systems:international and regional. In the correct operational paradigm, the seismic alerts are used to send out the watches and warnings. Then, data from observed sea level height are used to verify the existence of a tsunami. Other systems have been proposed to augment the warning paradigm. Forexample, it has been suggested that the duration andfrequency content of t-wave energy is indicative of an earthquakes tsunami potential.
