Minute by minute, many of the effects of the earthquake and tsunami the other day are still precarious. Thankfully, Japan is not a nation unprepared for those types of natural disasters, but its always good to give if you can to relief efforts. For simplicity's sake I donated to the Japan effort by the Red Cross, but there are many different groups raising money by now. Just remember to check that its reliable, of course.
Luckily everyone I know and their family in Japan were uninjured.
