Kilauea Volcano’s Kahaualea 2 flow is continued it erratic progress this week with Hawaiian Volcano Observatory cameras detecting smoke plumes and glowing areas at its farthest point.

Geologists mapped the most distant active extent of the flow at just over five miles northeast of the Puu Oo cone; the tip of the flow extends another 430 yards but has not moved since last mapped on May 14, according to the observatory.

The flow has been disrupted by deflation-inflation events that cause the lava supply to periodically dip. The front flow has advanced only 1.1 mile since it first stalled in November.

Rises and falls in the lava lake level are also common, episodic events at the volcano. The lake lies within a nearly cylindrical vent cavity within the east wall and floor of Halemaumau Crater. On Saturday, the lava lake level was measured at between 213 and 220 feet below the floor of Halemaumau crater.

Twenty-one earthquakes were strong enough to be located beneath the volcano from Friday to Saturday.

Gas emissions continued to be elevated.
