Detailed Description

Map showing the Kahauale‘a 2 flow in relation to the eastern part of the Big Island as of February 20, 2014. The front of the Kahauale‘a 2 flow was 7.8 km (4.8 miles) northeast of Pu‘u ‘Ō‘ō about one month ago. These forked fingers stalled during a prolonged deflation-inflation cycle (DI event) at Kīlauea's summit around January 23. Lava flows have since resumed and are approaching the stalled flow front with a new narrow lobe (red), with the farthest active flow on February 20 at about 7.4 km (4.6 miles) from the vent. The area of the Kahauale‘a 2 flow as of February 7 is shown in pink, while small areas of flow widening as of February 20 are shown in red. Older lava flows are distinguished by color: episodes 1-48b flows (1983-1986) are shown in gray; episodes 48c-49 flows (1986-1992) are pale yellow; episodes 50-55 flows (1992-2007) are tan; episodes 58-60 flows (2007-2011) are pale orange, and episode 61 flows (2011-2013) are reddish orange. The active lava tube is shown with a yellow line.
