Sarah Jaye Oliva, right, a Tulane University PhD student, works with Amani Laizer, a University of Dar-es-Salaam student, to make soil gas measurements in Tanzania in 2018. CO2 gas is flowing from a fissure where molten rock moved up a crack in the Earth’s crust after a Magnitude 5.9 earthquake and the Oldoinyo Lengai volcano erupted in 2007. Maasai pastoralists (middle ground) also observe.
