Peace Day and Kahauale‘a flow fields

Detailed Description

The active Peace Day flow as of March 15, 2013, is shown in light reddish orange, and the active Kahauale‘a flow north of Pu‘u ‘Ō‘ō is shown in pink. Widening of both flow fields between February 25 and March 15—subdivided because they are fed from separate sources—is shown in bright red. Changes to both flow fields above the pali are approximate. Older lava flows are labeled with the years in which they were active. Episodes 1-48b (1983-1986) are shown in gray; episodes 48c-49 (1986-1992) are pale yellow; episodes 50-55 (1992-2007) are tan; and episodes 58-60 (2007-2011) are pale orange. The contour interval for topographic lines shown on Pu‘u ‘Ō‘ō is 5 m.
