اقتصاد اليابان تساعد تايوان على بناء محطة في البحر لرصد الزلازل GMT الأحد 15 نوفمبر 2009 17:52 آخر تحديث : GMT الأحد 15 نوفمبر 2009 17:57 د. ب. أ. قراؤنا من مستخدمي تويتر يمكنكم الآن متابعة آخر الأخبار مجاناً من خلال حسابنا على تويترإضغط هنا للإشتراك تايبيه: تعتزم شركة يابانية مساعدة تايوان في بناء أول محطة لرصد الزلازل في أعماق البحر في الجزيرة. ونقلت وكالة الأنباء المركزية التايوانية "سي.إن.إيه" اليوم الأحد عن شين تزاي تشين، مدير المكتب المركزي للطقس في تايوان، أن شركة "إن.إي.سي" اليابانية فازت بعقد بناء المحطة قبالة الساحل الشمالي الشرقي لتايوان، وسيمكنها أن تقلل وقت رصد الزلزال بعشرة ثواني.
وستشيد المحطة shy; التي تبلغ تكلفتها 400 مليون دولار تايواني (12 مليون دولار أميركي) shy; على بعد 45 كيلومتراً قبالة مدينة توتشينج، وعلى عمق 2000 إلى 3000 متر تحت مستوى سطح البحر.
وتقع تايوان على حزام النار في المحيط الهادي، وتتعرض لحوالي 18500 زلزال سنوياً، من بينهم حوالي 1000 زلزال فقط يمكن الشعور بها.
وتقع معظم الزلازل في تايوان قبالة الساحل الشرقي، وتنتج عن الاحتكاك بين الصفيحة الفلبينية والصفيحة الأوروآسيوية. وكان آخر زلزال كبير قد هز إقليم تايتشونج وسط تايوان في 21 أيلول/سبتمبر عام 1999.
وتسبب هذا الزلزال، الذي بلغت شدته 7.3 درجة بمقياس ريختر في مقتل 2400 شخص، وإصابة ما يزيد على 10 آلاف شخص.
ويعتمد المركز التايواني لرصد الزلازل حالياً على مراكز الرصد الموجودة فوق سطح الأرض للحصول على معلومات فورية عن الزلازل.
ولا يمكن للمركز قياس شدة الزلازل قبل 18 ثانية من بدء الهزة. ويستغرق قياس شدة الزلزال وإرسال التحذير 30 ثانية على الأقل.
