Hawaiian Volcano Observatory is reporting normal activity from vents within Puʻu ʻŌʻō crater Monday.
No activity has been noted since a small overflow from a vent in the southeast portion of Puʻu ʻŌʻō crater took place at 9 a.m. Sunday. The flow reportedly lasted about an hour before stopping. This is the second period of unusual activity for Puʻu ʻŌʻō in the past several days.
On Thursday morning, lava erupted from a vent on the northeast side of the crater floor. Lava spread within the crater throughout the day before stopping around midnight Friday.
At the summit of Kilauea, activity continues as tiltmeters recorded inflation beginning Sunday afternoon. As of 8 a.m. Monday, HVO noted that tiltmeters were showing no significant change.
Measurements on Sunday morning showed the lava lake within the Overlook crater to be about 187 feet below the floor of Halema’uma’u.

Observation of the June 27 lava flow via webcam overnight showed activity on the flow field to the northeast of Puʻu ʻŌʻō. These breakouts are currently limited to about 5 miles of Puʻu ʻŌʻō.

Aug. 28: USGS scientists make observations from the edge of Puʻu ʻŌʻō’s current crater. Puʻu ʻŌʻō’s high point – the northwestern remnant of the original cone that formed in the 1980’s – is in the background. This higher ground provides a good perch for some of HVO’s webcams, located near the upper right. USGS/HVO photo.

Aug. 28: Lava flows in Puʻu ʻŌʻō erupted from a vent at the northeast edge of the crater and added a new layer to the crater floor on Aug. 27. This photograph looks northeast across the relatively smooth crater floor toward the vent that erupted, which is a spatter cone that appears as a faintly visible mound in the fume in the background.

Aug. 28: View of Puʻu ʻŌʻō from the south side, looking north. The current crater in Puʻu ʻŌʻō is only about half the diameter of Puʻu ʻŌʻō’s previous crater, which is defined by the rim of the tephra cone remnants in the foreground and background. That older crater’s western edge extended to about the left edge of the photograph. The current crater is 25–30 m (~80–100 ft) deep. USGS/HVO photo.
