New USGS Data Release - Sulfur dioxide emission rates from Kīlauea Volcano, Hawaii, 2008-2013
The USGS has recently published a data release that completes the 1979–2018 sulfur dioxide emission rate record for Kīlauea Volcano, Hawaii. Kīlauea Volcano on the Island of Hawai‘i, has one of the longest running volcanic sulfur dioxide gas (SO2) emission rate records in the world.
The volcano was in a state of nearly continuous eruption from 1983–2018, emitting large amounts of gas from the volcano's East Rift Zone (ERZ) during the entire eruptive period, and from the Overlook vent at the summit from 2008–2018. This data release presents our best estimates for ground-based SO2 emission rates from the two gas emission sources for the period 2008–2013. It provides revised data for previously published 2008–2010 emission rates and fills in the existing 2011–2013 data gap.
