New Breakout of Lava Mapped

This map shows recent changes to Kīlauea’s East Rift Zone lava flow field. The area of the active flow field as of January 12 is shown in pink, while widening and advancement of the active flow as of February 16 is shown in red. Older Puʻu ʻŌʻō lava flows (1983–2016) are shown in gray. The yellow line marks the trace of the active lava tube (dashed where uncertain).

At Puʻu ʻŌʻō, surface flows are occurring within about 2.4 km (1.5 mi) of the 61g vent and on the coastal plain. These flows pose no threat to nearby communities at this time.

The blue lines over the Puʻu ʻŌʻō flow field are steepest-descent paths calculated from a 2013 digital elevation model (DEM), while the blue lines on the rest of the map are steepest-descent paths calculated from a 1983 DEM (for calculation details, see http://pubs.usgs.gov/of/2007/1264/). Steepest-descent path analysis is based on the assumption that the DEM perfectly represents the earth’s surface. DEMs, however, are not perfect, so the blue lines on this map can be used to infer only approximate flow paths. The base map is a partly transparent 1:24,000-scale USGS digital topographic map draped over the 1983 10-m digital elevation model (DEM).

This small-scale map shows Kīlauea’s active East Rift Zone lava flow field in relation to the southeastern part of the Island of Hawaiʻi. The area of the active flow field as of January 12 is shown in pink, while widening and advancement of the active flow as of February 16 is shown in red. Older Puʻu ʻŌʻō lava flows (1983–2016) are shown in gray.

Update Map of Lava Flow Field

This map shows recent changes to Kīlauea’s East Rift Zone lava flow field. The area of the active flow field as of December 14 is shown in pink, while widening and advancement of the active flow as of January 12 is shown in red. Older Puʻu ʻŌʻō lava flows (1983–2016) are shown in gray. Surface flows are focused on a branch of the flow east of Puʻu ʻŌʻō that has been active since late last year. The front of that flow branch has stalled, but there are weak scattered breakouts upslope along its length.

Disregard the area around the Kamokuna ocean entry, where the Kamokuna lava delta collapsed on New Year’s Eve. The lava flow polygons in these maps are layered to show additions to flow. As such, they do not show where material has been removed, such as by lava delta collapse.

The blue lines over the Puʻu ʻŌʻō flow field are steepest-descent paths calculated from a 2013 digital elevation model (DEM), while the blue lines on the rest of the map are steepest-descent paths calculated from a 1983 DEM (for calculation details, see http://pubs.usgs.gov/of/2007/1264/).

New Lava Flow Map Shows Vicinity of Ocean Entries

This map shows recent changes to Kīlauea’s East Rift Zone lava flow field at the coast. The area of the active flow field as of August 2 is shown in pink, while widening and advancement of the active flow as mapped on August 12 is shown in red.
