| Zusammenfassung |
| Indonesia hosts 79 active volcanoes, representing 14% of all active
volcanoes worldwide. However, little is known about their SO2
contribution into the atmosphere, due to isolation and access difficulties.
Existing SO2 emission budgets for the Indonesian archipelago are based
on extrapolations and inferences as there is a considerable lack of field
assessments of degassing. Here, we present the first SO2 flux
measurements using differential optical absorption spectroscopy (DOAS) for Papandayan and Bromo, two of the most active
volcanoes in Indonesia. Results indicate mean SO2 emission rates of
1.4 t d−1 from the fumarolic activity of Papandayan and more than
22–32 t d−1 of SO2 released by Bromo during a declining eruptive
phase. These DOAS results are very encouraging and pave the way for a better
evaluation of Indonesian volcanic emissions. |
