Something about this week

I play as a reporter in a TV show and I talked took about natural disasters in the world, especially the last tsunami in Indonesia.  (Note "to play" a role, without "as", although you do use it in "I act as the manager while our manager is on sick leave", etc.  Note "especially".  "Tsunami" isn't capitalized.)

I was shocked when I saw that news.  Fortunately here in Mexico we never have had an earthquake of with that magnitude but anybody is immune from of any kind of natural disaster.  (Note "news" = noticias.  Note "an earthquake of that magnitude".  Did you mean "Nobody is completely immune from all natural disasters", i.e., you can't assume you'll always be safe from such events?)

I don't know how many people were injured but I hope they are be in safe.  (We don't exactly have the subjunctive in English, but you'd just use the present tense in this case, compared with "espero que estén a salvo" or similar.

Oh! I'm sad now for that.  (I'd say "Now I'm sad about that.")
