Final estimates of the emissions from the Holuhraun eruption based on ground-based measurements - 22.1.2018

A new paper published last week in Geosciences reports that the Holuhraun eruption released the most SO2 (sulfur dioxide) of any effusive (non-explosive) eruption in the world on an annual basis since 1978, the advent of satellite monitoring of volcanic eruption clouds. The Holuhraun eruption released 16 times more SO2 (sulfur dioxide, 9.6 Mt) and almost twice as much CO2 (carbon dioxide, 5.1 Mt) as one year´s worth of anthropogenic emissions within Iceland (0.06 Mt SO2 and 3 Mt CO2 in 2015).  Read more
