We on this side of the world, well, we can donate to the International Red Cross or Doctors without Borders. Sending "things" is not practical.
I would assume that my government has offered assistance to NZ. They had better!
I saw the photos. It is absolutely shocking. Were those buildings that pancaked designed for earthquake safety? or did they predate that sort of thing? around here, ALL buildings built since about 1995 must be earthquake safe (of course, nothing is totally safe, but design makes a huge differenc.)
Hope that you are ok, and all your loved ones. So sorry for those not so lucky.
