Bardarbunga (Central Iceland): The eruption continues with little variation. The Nornahraun lava field is now almost 80 square km in size. An extensive lava tube system has formed inside it, bringing supply of lava to the outer areas.
Earthquake activity remains significant under the caldera, which continues to subside. Occasional quakes reach magnitudes above 5.
Kilauea (Hawai’i): The June 27th lava flow continues to advance slowly, at a rate of approx. 100 m per day. The active northern flow front was approx. 800 m from the west edge of the Pahoa Marketplace and about 1 km from Highway 130, measured in a straight line.
The lava flow is now less than 1 km (0.7 mi) from the Pahoa marketplace. During yesterday’s overflight, it was seen that had advanced about 340 m during the previous 24 hours.
Its front has split into two branches, one following the steepest descent path in the area and another following a “tributary” path to the north that intersects the main descent path a few hundred meters.
Several breakouts were also scattered along the edges and interior of the flow 2 to 3.7 km (1.2 to 2.3 mi) upslope of the flow front, similar to activity of the past several days.
