First time ever: Live monitoring of flood basalts regarding sulphur

For over three months now the Holuhraun fissure eruption has been ongoing.

This is the first time in the modern age we have the opportunity to study the environmental impact of a flood basalt as it happens. Now Dr Evgenia Ilyinskaya, from the BGS Volcanology team, has led and won her first ever NERC research grant to allow a multidisciplinary team to continue this cutting edge research. Here she explains more about the work and why it's so important.

The project will contribute to two broad issues with sulphur:

  • The magmatic controls on the sulphur content of flood basalt eruptions. There is evidence to suggest we may have underestimated the sulphur output from older eruptions by several orders of magnitude.

  • The lifetime of sulphur in the atmosphere which is critical for both the magnitude and scale of the environmental perturbation.
