Kilauea volcano update: Lava threat to homes lessens, for now
Tuesday Sep 09, 2014 03:17 AM | VON: PO
The latest updates from authorities show no significant change in the path of the lava flow, only advancement through the jungle away from houses, for now.
September 8, 2014 eruption map by USGS-HVO.
The flow has advanced relatively quickly covering roughly 1/2 mile (3/4 km) in the past 2 days, but typically that rate is hard to sustain for long. Between the six days of Aug 6-12, the map shows the flow made about 1 mi forward progress, but during the next six days the flow advanced only half that distance, totaling 1.5 mi (2 km) in 12 days.
If the flow follows the easiest downhill path (marked by the blue line crossing the red flow tip on the map), it has more or less 4.5 mi (6 km) to cover until it would reach Highway 130, fortunately with no houses on the way. If it follows a similar rate of advance as Aug 6-18, we can expect that will take about 1 month to threaten the closest infrastructure, or by early to middle of October.
The big "if" remains that nothing changes with the lava pipeline upstream. The presence of big ground cracks in the area would seem to make such changes more likely and there's a chance this flow never reaches the highway, but we remain vigilant and respectful of the volcano's power.

Lava flows continue to advance downhill through the jungle on a path that will miss Kaohe Homesteads, having first entered and overtopped several large ground cracks on Kilauea volcano's east rift zone. The farthest lava front is now 13.3 km (8.3 miles) from the vent and 1.2 km (0.7 miles) from the east boundary of the Wao Kele o Puna Forest Reserve, and moving northeast parallel to the boundary. ...

According to officials, the June 27th lava flow has reemerged for the second time from a huge ground crack along Kilauea's east rift zone, this time approximately 13.2 km (8.2 miles) from the vent and 1.3 km (0.8 miles) from the eastern boundary of the Wao Kele o Puna Forest Reserve, but still continues moving through the ground crack to within 1.1 km (0.7 miles) from the boundary. ...

The June 27 lava flow remains active and is now only approx. 2 km from the nearest inhabited area. Its farthest front had been spreading in the forest over the past few days and was seen to be spilling into yet another ground crack about 12.6 km (~7.8 miles) from the vent and about 1.9 km (~1.2 miles) from the eastern boundary of the Wao Kele o Puna Forest Reserve.

The lava flow branch that entered and followed a deep ground crack on Kīlauea's East Rift Zone last week has resurfaced and is now forming a small lava island inside the forest. Its farthest point is 11.4 km (7.1 miles) from the the vent on Puʻu ʻŌʻō, and 3.1 km (1.9 miles) from the eastern boundary of the Wao Kele o Puna forest reserve. [mehr]

A piece of the crater walls of the Halema'uma'u lava lake collapsed on 23 July and triggered a small explosive eruption. Liquid spatter was ejected to the outer perimeter of the pit crater (including webcam position and the closed observation area) and an ash plume was generated. ... [mehr]
