Detailed Description

Map showing the Kahauale‘a 2 flow in relation to the eastern part of the Island of Hawai‘i as of April 18, 2014. The most distant active front of the Kahauale‘a 2 flow had retreated slightly, probably in response to a DI event which occurred at Kīlauea's summit over past week, and was 7.5 km (4.7 miles) northeast of Pu‘u ‘Ō‘ō. Most flows were within the interior part of the flow, but a few fingers were advancing very slowly into thick forest. The area of the Kahauale‘a 2 flow as of April 7 is shown in pink, while widening of the flow since then is 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 (dashed where its position is poorly known).
