Detailed Description

Scientists collect volcanic gas data using a Fourier Transform Infrared spectrometer (FTIR). During the Kamoamoa eruption, sulfur dioxide emission rates from Kīlauea’s East Rift Zone reached the highest levels since the episodes of high-fountaining at Pu‘u‘ō‘ō (1983–1986) with an average rate of 8,500 tonnes per day and a peak value of 11,000 tonnes per day.
