After devastating natural disasters, mobile phone networks, satellites and other computer software are often used to help to pinpoint where help is needed the most.  They are crucial for the creation of crisis maps.

The power of the mobile phone and other social media became clear in the aftermath of the tsunami and earthquake in Japan.  Just hours after disaster struck, Japanese volunteers used social media information  to create a crisis map.  The map indicated hazardous areas and emergency services.  Hundreds of people each day posted updates to the map on the Internet, including information from radio stations.

Crisis maps also helped with relief efforts in Haiti. Thousands of text messages provided information to international aid organizations about shelter, food supplies and sanitation.  A mapping team helped pinpoint search and rescue requests for people trapped in the rubble.

Sheldon Himelfarb is the director of peacebuilding at the U.S. Institute of Peace in Washington. "The word went out that if you texted a certain short code number with your call for help, it would be captured, mapped and it would enable responders to help… We saw very quickly how the emergency responders of all sorts, from the Red Cross to the military to the NGOs started to rely on this map," Himelfarb said.
