If you would like to buy the DVD, just email/ring Trócaire and they'll sell you one for €6. The money's going to charity so it's a good cause as well as a good teaching resource!
The worksheets are available for free here: http://www.trocaire.org/sites/trocaire/files/pdfs/edu/age/talesofdisaster.pdf
It's really well laid out with ideas for extension activities that could be done for different subjects.
They have some free resources that would be useful for geography at http://www.trocaire.org/resources/primary-resources.
