Episodes 1–48b (1983–1986) are shown in dark gray; episodes 48c–49 (1986–1992) are pale yellow; episodes 50–53 and 55 (1992–2007) are tan; episode 54 (1997) is yellow; episode 58 (2007–2011) is pale orange; the episode 59 Kamoamoa eruption (March 2011) is at left in light reddish orange; and the episode 60 Pu‘u ‘Ō‘ō overflows and flank breakout (Mar–August 2011) is orange. The currently active flow (episode 61) is shown as the two shades of red—pink is the extent of the flow from September 21, 2011, to April 5, 2012, and bright red marks flow expansion from April 5 to 11. The April 11 field mapping only covered flows on the coastal plain, where most activity is currently focused; additional minor expansion between April 5 and 11 may have occurred farther upslope which is not shown here. The active lava tube is delineated by the yellow line within the active flow field. The contour interval on Pu‘u ‘Ō‘ō is 5 m
