Kīlauea's ERZ flow field

Small-scale map showing Kīlauea's east rift zone flow field as of July 26, 2013. The active Peace Day flow, which is carrying lava to the ocean, and the inactive Kahauale‘a flow from early 2013, are light reddish orange. The active Kahauale‘a 2 flow north of Pu‘u ‘Ō‘ō, is shown in shades of red, with bright red showing flow expansion since June 11. 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 Peace Day lava tube is shown by the yellow line. The Peace Day tube where it crosses the coastal plain is not obvious and has not been mapped. The contour interval for topographic lines shown on Pu‘u ‘Ō‘ō is 5 m.
