Kīlauea's ERZ flow field

Small-scale map showing Kīlauea's east rift zone flow field as of November 16, 2013. The Kahauale‘a 2 flow continues to advance slowly toward the northeast from Pu‘u ‘Ō‘ō. Its area as of November 7 is shown in pink, while advancement of the flow as of November 16 is shown in red. Older lava flows are labeled with the years in which they were active: 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; and episodes 58-60 flows (2007-2011) are pale orange. The active lava tube is shown with a yellow line. Late on November 15, a small flow broke out from the Peace Day tube east of Pu‘u ‘Ō‘ō. The Peace Day flow (light orange) has been inactive since November 7. This tiny breakout suggests the tube was briefly re-occupied, or, alternatively, the tube had been receiving a trickle of lava all along, slowing filling it until the pressure had risen sufficiently to break through the tube roof.
