GEOGRAPHY HOLIDAY HOMEWORK - 1
PROJECT ON DISASTER MANAGEMENT [ FA1 activity]
Submission Day & Date: 1st geography period after your summer vacations
General instructions:
1. The project should be done on the interleaf punch sheets.
2. Supplement the project with the help of pictures, maps, diagrams etc.
3. Be very careful with the clarity, neatness, presentation and completion of your
project work on time, as marks will be given for the same.
The Union home ministry's disaster management experts have warned of a bigger
catastrophe, earthquakes with a magnitude of 8.2 or greater on the Richter scale which
may hit the already ruptured Himalayan region. They say quakes with higher intensity
than the one that struck Manipur are likely to rock the region in future. The tectonic shift
a series of these recent earthquakes have caused in the region -- Manipur 6.7 (Jan 2016),
Nepal 7.3 (May 2015) and Sikkim 6.9 (2011) -- have re-ruptured the plates that had
already developed cracks during previous temblors. This has led to conditions which
might trigger multiple earthquakes which may go up to 8.0 in magnitude. Stress has
increased in the mountains of north-east since the Nepal earthquake and has not been
fully released, it has only become worse. The collision between the Himalayan plate in
the north and the Indo-Burmese plate in the east and the risk created as a result is the
highest at this moment.
After reading this news piece, we can easily make out that this disastrous situation
can occur again at any point of time. Now imagine that you were there in some
school at the time of some devastating earthquake. Keeping the situation in mind,
answer the following questions.
1. If you were in the class what would you’ve done at that particular point of
time?
2. If you manage to save yourself but you find that a friend of yours has got hurt.
What steps are you going to take to help him/her?
3. If you are in a situation where you find that you are unable to find the required
equipment for rescuing people, what would you do?
4. Your school’s first aid kit has got buried in the rubble. How can you give first
aid or medical help to the other students?
5. How would you convert the locally available products to the best possible
use?
6. How can you communicate and appeal for help from outside world?
7. What precautions are you going to take before helping others?
8. How much of your own safety should be compromised in trying to help
others?
