Kīlauea continues to erupt at its summit and East Rift Zone. During the past week, the summit lava lake level varied between about 30 m and 35 m (98–115 ft) below the vent rim within Halema‘uma‘u Crater. On the East Rift Zone, the June 27th lava flow is inactive.

The eastern Pu‘u ‘Ō‘ō breakout remained active, producing a lava flow (informally called the “61g flow”) that continued to advance to the southeast. The flow is 5.1 km (3.2 miles) long, and the flow front was about 100 m (330 ft) from the northern boundary of the abandoned Royal Gardens subdivision. Over the past week the flow front has advanced at a rate of roughly 100 m per day (330 ft per day). Bright incandescence is visible in the overnight webcam views of the active lava flow field, marking lava tube skylights and scattered breakouts near the flow front. No lava flows were threatening nearby communities.

Mauna Loa is not erupting. Seismicity rates have decreased since the earthquake activity recorded in late May, but remain above background levels. Deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone continues, with inflation recently occurring mainly in the southwestern part of Mauna Loa’s magma storage complex.

No earthquakes were reported felt on the Island of Hawaiʻi this past week.

Time-lapse movie from a camera positioned on the southeast flank of Puʻu ʻŌʻō, looking toward the active flow advancing to the southeast. The breakout point is at the left edge of the image, and the mid-field skyline at the right is roughly coincident with the top of the pali. June 16-23, 2016. Images courtesy of USGS/HVO

Time-lapse movie from images gathered from a temporary thermal camera looking into Pu’u ‘O’o Crater. The temperature scale is in degrees Celsius up to a maximum of 500 Celsius (932 Fahrenheit) for this camera model, and scales based on the maximum and minimum temperatures within the frame. Thick fume, image pixel size and other factors often result in image temperatures being lower than actual surface temperatures. June 16-23, 2016. Images courtesy of USGS/HVO

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 on June 16 is shown in pink, while widening and advancement of the active flow field as mapped on June 23 is shown in red. The area covered by the inactive June 27th flow is shown in orange. The Puʻu ʻŌʻō lava flows erupted prior to June 27, 2014, are shown in gray. 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 a 1983 10-m digital elevation model (DEM).
