الكوارث الطبيعية

تعريف الكوارث الطبيعية
يمكن تعريف الكوارث الطبيعية بأنّها مجموعة من الأنشطة الطبيعية العنيفة المتطرفة التي تحدث بشكل مباغت ومفاجئ لا يسمح للإنسان باتخاذ التدابير الاحتياطية اللازمة للتخفيف من أثارها التدميرية، علاوة على ذلك فهذه الأنشطة تصيب أماكن مأهولة بالسكان مسببة خسائر بشرية فادحة، ولا يمكن إعفاء الإنسان من المسؤولية، فالأعمال البشرية الجائرة بيئياً لها أحياناً دور كبير في حدوث مثل هذه الكوارث.

أسباب حدوث الكوارث الطبيعية
هنالك سببان رئيسيان لوقوع الكوارث الطبيعية هما:
الظواهر الطبيعية: يعزي السبب وراء هذه الظواهر إلى إطلاق الأرض جزءاً من طاقتها الهائلة ليصل تأثيرها إلى سطح الأرض، ومن الأمثلة على هذه الظواهر: الزلازل، والبراكين، والأعاصير.
الأنشطة البشرية: يقوم الإنسان بالعديد من الأنشطة الغير مسؤولة؛ كالاختيار الخاطئ لمواقع مساكنه ومنشآته، وإهمال اتخاد التدابير اللازمة للحماية من مخاطر الظواهر الطبيعية.

أمثلة على الكوارث الطبيعية
هناك العديد من الأمثلة على الكوارث الطبيعية، منها ما يلي:
الزلازل: تسبب حركة الصخور في جوف الأرض ارتجاجات سريعة مفاجئة تدعى الزلازل، وهذه الزلازل تتفاوت في شدتها وخطورتها من منطقة لأخرى، فمثلاً تصنف ألاسكا وكاليفورنيا من المناطق النشطة زلزالياً.

ثوران البراكين: تطلق البراكين مجموعة من الاندفاعات كالحمم البركانية التي تعتبر أكثرها خطورة لدرجة حرارتها العالية وقدرتها على تدمير كل ما يعترض طرقها، كما أن ثوران البراكين قد يتسبب بحدوث كوارث طبيعية أخرى؛ كأمواج تسونامي، والزلازل.

Introduce Yourself (Example Post)

This is an example post, originally published as part of Blogging University. Enroll in one of our ten programs, and start your blog right.

You’re going to publish a post today. Don’t worry about how your blog looks. Don’t worry if you haven’t given it a name yet, or you’re feeling overwhelmed. Just click the “New Post” button, and tell us why you’re here.

Why do this?

  • Because it gives new readers context. What are you about? Why should they read your blog?
  • Because it will help you focus your own ideas about your blog and what you’d like to do with it.

The post can be short or long, a personal intro to your life or a bloggy mission statement, a manifesto for the future or a simple outline of your the types of things you hope to publish.

To help you get started, here are a few questions:

  • Why are you blogging publicly, rather than keeping a personal journal?
  • What topics do you think you’ll write about?
  • Who would you love to connect with via your blog?
  • If you blog successfully throughout the next year, what would you hope to have accomplished?

You’re not locked into any of this; one of the wonderful things about blogs is how they constantly evolve as we learn, grow, and interact with one another — but it’s good to know where and why you started, and articulating your goals may just give you a few other post ideas.

Can’t think how to get started? Just write the first thing that pops into your head. Anne Lamott, author of a book on writing we love, says that you need to give yourself permission to write a “crappy first draft”. Anne makes a great point — just start writing, and worry about editing it later.

When you’re ready to publish, give your post three to five tags that describe your blog’s focus — writing, photography, fiction, parenting, food, cars, movies, sports, whatever. These tags will help others who care about your topics find you in the Reader. Make sure one of the tags is “zerotohero,” so other new bloggers can find you, too.
