Geoscientists Without Borders® (GWB) has been supporting the humanitarian application of geosciences around the world for the last 10 years. GWB was formed after the 2004 Indian Ocean earthquake and tsunami that killed more than 225,000 people and caused massive destruction in Sumatra, Indonesia. Craig Beasley, then SEG president, called on members to use their geoscience skills and knowledge to help prevent catastrophic disaster in the future. It took four years to raise funds and put the structure in place to form GWB. The first projects were approved for funding in 2008. Since its establishment, GWB has awarded more than US$2.75 million to 36 projects in 27 countries. Projects have focused on water management, habitat management, pollution mitigation, archaeology, and earthquake, landslide, tsunami, and volcano hazard preparedness.
