This is a strange eruption, there are early indications that the lava from this eruption is very deep, and could mean a long eruption as it's not from a shallow lava lake below, if this is the case this eruption would be very unique and rare.

An examination of its volcanic products suggests that the magma flows from a depth of 17-20 km (10-12 mi), and is of a more primitive sort than we’ve seen before.
Lava flow from shield volcanoes is generally slow, but it can continue for a long time - possibly years. Such a scenario cannot be ruled out with regard to the current eruption in Geldingadalur, Fagradalsfjall mountain, states geologist Magnús Á. Sigurgeirsson. The magma flows at a volume of 5-10 m3/second.
Among well-known shield volcanoes on the Reykjanes peninsula is Þráinsskjöldur, formed about 14,100 years ago. Another shield volcano, better known, is Skjaldbreiður, northeast of Þingvellir National Park, created 9,000 years ago.
