Neither introduction nor motivation are required for this special section of The Leading Edge dedicated to the SEG Foundation's program Geoscientists Without Borders (GWB). Natural disasters such as earthquakes, tsunamis, volcanic eruptions, killer storms, landslides, and other natural disasters occur all too frequently. People across the planet struggle to provide themselves the basic necessities of life such as water, food, and energy. While we, as geophysicists, cannot control nature or eliminate the human condition, it is possible for us to play a role in mitigating these problems and improving human lives. We can all contribute as individuals, but the goal of GWB is larger: to effect long-term and sustainable aid to people in need through technology transfer and training involving the next generation of geoscientists.
