Eruption - Day 12
- Eruption continues
- Increased measurements of gas
The eruptive activity at Holuhraun continues at similar intensity. Lava flows at similar rates as yesterday. The lava is flowing towards East but widens slightly towards North. The main flow follows the river bed of Jökulsá á Fjöllum. No explosive activity due to the lava and river water interaction has been observed, but steam rises from the lava. Earthquake activity in the caldera of Bárðarbunga remains similar to that of the last days. GPS observations show insignificant crustal movements supporting the assumption that the amount of magma flowing into the dyke continues to be similar to the magma erupted to the surface.
Forecasts indicate that high concentrations of sulphuric gases may be expected in the northern part of the Eastern fjords, Fljótsdalur, Hérað, Jökuldalur, and Vopnafjörður. High concentrations could occur in other areas as well. People who feel discomfort are advised to stay indoors, close the windows and turn off air conditioning. Measurements of air quality can be found on the webpage loftgaedi.is. The Meteorological Office issues warnings if conditions change to the worse. Instructions from the office of the Chief Epidemiologist and The Environmental Agency can be found on their web-sites.
