The new eruption started in Holuhraun, north of the Dyngjujökull Glacier along the same volcanic fissure that appeared on Friday morning, says accuweather.com.
A very calm but continuous lava eruption is under way, according to the Met Office.
However, bad weather due to the remains of former Hurricane Cristobal have prevented flyovers, limiting direct observation of the eruption.
Additionally, even though earthquake activity continues, the same bad weather has made the detection of smaller earthquakes challenging.
