Episode 61 (Peace Day) flow field...

Detailed Description

The currently active Peace Day flow (episode 61) is shown as the two shades of red—light red is the extent of the flow from September 21, 2011, to January 4, 2013, and bright red marks the mapped flow expansion from January 4 to January 30. While there have been small changes near the coast, most of the change is related to lava flows that have spilled from the Pu‘u ‘Ō‘ō crater over the past few weeks. 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 50-53 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) are orange. The contour interval for topographic lines shown on Pu‘u ‘Ō‘ō is 5 m.
