The main lava flow had only advanced a small distance during 6-7 December, at a rate of about 6 m per hour, possibly due to a significant breakout that had occurred about 4.5 km upslope of the flow front. Lava erupting from Fissure 3 was greatly reduced by the morning of 8 December.

Lava flows continue to spill out from Fissure 3 on the northern slope, currently (as of 12:00 PM local time today) about 2.15 mi (3.5 km) from the Daniel K. Inouye Highway (Saddle Road). The lava is still traveling on relatively flatter ground, forming small overflows from main channels. It slowed down significantly over the past few days as expected to an average rate of 20 feet per hour (6 meters per hour).
The advancing rate may be highly variable as the lava is flowing on flat ground for now, which makes it difficult to estimate an arrival time to reach Saddle Road. On the flat ground between Mauna Loa and Mauna Kea, lava flows a…Open article
