Tsunamis, earthquakes, disaster relief... Just Give?
Three Japanese scientists have done lab or field research with me over the years. All survived the earthquake and tsunami, although they may have lost friends or relatives. I don't know anyone in Haiti, but they may need help even more than Japan does. We can't prevent earthquakes or other natural disasters -- reducing production of greenhouse gases, not building on floodplains, and protecting mangroves might reduce hurricane and flooding risks somewhat -- but investing more in disaster recovery could reduce death and disruption. The US military has made some positive contributions in this area and we might find that having them do more disaster relief would reduce the number of people who want to attack us more efficiently than trying to kill them all has.
Meanwhile, we can support Red Cross/Crescent, Doctors Without Borders, etc. Recently, I've been donating through JustGive.org. They will pass your donation to the groups you select, minus a small fee, and can withhold your address or other contact information. That way, I can support the groups I like, without getting monthly letters asking for more money, from every group they to which sell my address.
