Episode 57: Building canals - how science and friendship changed a town

On this episode of Seismic Soundoff, we start a journey with a team of scientists partnering with a former Inca city in Perú. This small, rural village of 4,000 people will welcome a Geoscientists Without Borders team to help build a reservoir and irrigation canal network that will benefit 120 farmers. But their work seeks to not only directly impact these families, but support each generation of Zuritaneos that come after and contribute to the scientific understanding that will benefit the world.
