It is the worst catastrophe in Haiti's history: on January 12, a devastating earthquake struck near the capital, Port-au-Prince, killing thousands of people.
The International Red Cross  has said that 3 million people--nearly a third of Haiti's population--will need food, water and shelter for months to come.
The earthquake, which measured 7.0 on the Richter scale, destroyed or seriously damaged houses, schools, and many of the city's major buildings including the National Palace, the Parliament, the Cathedral, the Ministries of Economy and Finance and Public Works, the Tax Office, the United Nations Stabilization Mission headquarters, and the World Bank’s office.
The international community is rallying efforts to help the country deal with the aftermath of the earthquake. Here are a few places where you can learn more about the ongoing efforts, and how you can help:
