Dyngjuhals fissure system has not yet been properly researched, but is
considered to be about 10 km wide and 25-50 km long comprising the
shield volcano Trolladyngja and even extending to the Dyngjufjoll
It continues to the south under the western part of the
Dyngjujokull glacier tongue in the direction of the ice covered
Bardarbunga central volcano.
to eight volcanic fissures, 5-10 km long, with SW-NE directions are
side-by-side on the Dyngjuhals Ridge, each dotted with rows of scoria
craters of different sizes.
Those fissure eruptions have created lava fields along the
southern part of River Skjalfandafljot.
The limited research of the area suggests volcanic activity
during Holocene and historical times.
The Kattarbudir Crater on the picture above
was erased during a recent advance of the glacier snout Dyngjujokull and does not exist any
