Breakouts have been active recently in several locations on the coastal plain. The sluggish flows in this photo were about 1.6 km (1 mile) out from the base of the pali, with a more active patch of breakouts mauka of this location. In addition, several areas of breakouts were active very close to the shoreline and ocean entry. In this photo, one of the last remaining sections of uncovered roadway in Royal Gardens subdivision is visible in the brown patch (near the white fume) in the upper right portion of the image. This is Ali`i Avenue, on a steep section of the pali. Photo courtesy of USGS/HVO

The ocean entry near Kupapa`u Point remains active, with no major changes in appearance over the past few weeks. In this view, the two main entry points are visible, with a smaller third entry point (out of view) just beyond these. Photo courtesy of USGS/HVO

A lava lake within the Halema`uma`u Overlook vent produced nighttime glow that was visible from the Jaggar Museum overlook and via HVO’s Webcam during the past week. The lake level fluctuated in response to summit deflation–inflation cycles, ranging between about 25 and 60 m (80–200 ft) below the floor of Halema`uma`u.

On Kilauea’s east rift zone, breakouts from the Peace Day tube remain active above and at the base of the pali and on the coastal plain. Small ocean entries are active on both sides of the Hawai`i Volcanoes National Park boundary. In addition, the Kahauale`a flow, fed directly from a spatter cone on the northeastern edge of Pu`u `O`o’s crater floor, continues to advance slowly toward the northeast across a plain of 1980s-era `a`a flows.

There were no felt earthquakes in the past week on the Island of Hawai`i.
