| Zusammenfassung |
| Along with the rifting event and caldera subsidence in the Bárðarbunga central volcano in
Iceland, an ongoing (as of January 2015) effusive basaltic eruption started in Holuhraun in
the end of August 2014. Associated with the eruption is a plume of juvenile water vapour and
gases, mainly SO2 and CO2. The plume contains very little ash. Due to the effusive nature of
the eruption, the plume is weak and controlled to a large extent by atmospheric conditions,
including winds and stability. We present a time series of the plume height, derived from
various sources, including web cameras, flight and field reports. The maximum plume height
close to the eruption site has mainly been in the range 1-3 km above ground and the middle of
the plume few kilometers from the eruption site often about 1 km above ground.
We show comparison of the plume height time series to atmospheric conditions. |
