USGS scientists monitor gases on Kīlauea's lower East Rift Zone
On November 8, 2019, USGS volcano scientists visited Kīlauea's Lower East Rift Zone to measure ambient gases, as well as the soil carbon dioxide (CO2) flux and temperature. This photo, looking in a southeast direction, shows some steaming uprift of the 2018 fissure system. Steaming in this area is the result of continued migration of heat due to movement of subsurface ground water as the area recovers from the 2018 eruption. USGS image by P. Nadeau.
