Ocean Entry & Coastal Plain Breakouts Remain Active

December 15, 2012

Kilauea Volcano: A small collapse of the spatter cone that had built up around the northeast lava pond in Puʻu ʻŌʻō resulted in a brief gush of lava onto the crater floor. (USGS)

This thermal image shows the scattered breakouts on the coastal plain and the ocean entry near Kupapa`u. In addition to these coastal plain flows, several breakouts were active near the top of the pali, around the northern boundary of Royal Gardens subdivision. (USGS)

The ocean entry (at center of image) near Kupapa`u remains active, with a weak and wispy plume. The light colored area on the coastal plain shows the recently active flows. (USGS)

Map showing the extent of lava flows erupted during Kīlauea’s ongoing east rift zone eruption and 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 Puʻu ʻŌʻō overflows and flank breakout (Mar–August 2011) are orange. 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 November 30, 2012, and bright red marks the mapped flow expansion from November 30 to December 14. There may have been minor flow margin changes upslope, in and above the upper part of Royal Gardens, which have not been mapped and are not shown on this map. The active lava tube is delineated by the yellow line within the active flow field. Incipient tubes extend onto the coastal plain to feed the currently active flows, but these have not been mapped. The contour interval for topographic lines shown on Puʻu ʻŌʻō is 5 m. (USGS)
