M5.1 quake occurs at northern rim of  Bardarbunga caldera: IMO

Centered at 64.675°N, 17.415°W, about 6.6km NE of Bardarbunga, the quake occurred at a depth of 5.2 km [USGS/EHP: 64.723°N 17.390°W depth=7.5km] on Sunday at 12:01:45GMT, said Iceland Met Office (IMO).

The quake was the largest to strike Bardarbunga volcanic system since a magnitude 5.4 shock on Saturday.

Meantime, a large fissure eruption continues in Holuhraun lava field, north of Vatnajokull [Glacier of Lakes.]

“A lava eruption started in Holuhraun shortly after 04 AM, on the same volcanic fissure, which erupted earlier this week. The fissure is estimated to be 1.5 km long.”

The lava extruding from the fissure was estimated at 1 km wide, 3 km long and several meters deep, oozing down in a northeasterly direction. The flow rate was about 1,000 m³ per second, said IMO.

The Aviation Color Code for Bárðarbunga has been downgraded from “red” to “orange” [because no ash has been detected] and the alert level for Askja to “yellow,” said IMO.
