Following days of deflationary tilt, Kilauea summit began to show inflation as part of its current DI event on Thursday.
Hawaiian Volcano Observatory reports that along with the change in tilt, the lava lake within the Overlook crater has fluctuated slightly. However, no reports of major lake rise has been reported.
Seismic activity below the summit of Kilauea remains at background levels. HVO has reported several small earthquakes below the summit, in addition to a few across the south flank of Kilauea.
Puʻu ʻŌʻō has not seen any changes in activity as the incandescent outgassing vents within the crater remain. Seismicity has continued at background levels.

HVO conducted an overflight of the June 27, 2014 lava flow on Thursday. During the flight, HVO reports observation of a decrease in activity. It is believed that the decrease could have been in connection with the recent summit deflation. Breakouts were spread out about 2.5 to 5 miles to the northeast of Puʻu ʻŌʻō.
