Monitoring lava flows on ground and in sky

This month, our Volcano Watch articles are focusing on how the U.S. Geological Survey Hawaiian Volcano Observatory monitors Kilauea’s June 27 lava flow. Last week, we covered satellite monitoring; this week, we will discuss how HVO scientists track lava flow activity from the air and the ground.

June 27 lava flow shows little sign of advancement

Hawaii County Civil Defense’s assessment of the June 27 lava flow as of 8:15 a.m. Saturday showed the original flow front and south margin breakout remain stalled. The breakout along the north side of the flow continues to be active and widening; however, it has shown little sign of advancement since midweek.

Lava breakout creeps toward Highway 130 in Pahoa

The leading edge of a breakout from the June 27 lava flow advanced about 15 yards between Monday and Tuesday, Hawaii County Civil Defense Administrator Darryl Oliveira said Tuesday. The breakout remains about 0.4 mile upslope of Highway 130, north of Pahoa.
