Kilauea Summit Update – 5/6/15

Posted May 6, 2015, 08:35 AM HST

Over the past week, the summit lava lake in the Overlook crater rose and spilled out onto the floor of Halemaʻumaʻu Crater, creating the dark flows in the south part of Halemaʻumaʻu, which can be seen on the left side of crater in the photo. USGS/HVO photo.

Kilauea’s summit has remain relatively steady since Tuesday morning. According to Hawaiian Volcano Observatory, the area saw no significant change in tilt at the summit and the lava lake has either been at or near the Overlook crater rim.

No overflows onto the Halema’uma’u Crater floor were reported by HVO during the past day. HVO officials say that the area in which the overflows during the past week spilled over onto the Halema’uma’u Crater floor is about 28 acres.

Beneath Kilauea’s summit and the upper East and Southwest Rift Zones, seismicity continues to be high.

At Puʻu ʻŌʻō, the tiltmeter along the north flank recorded deflationary tilt. In addition, HVO scientists say a small lava flow began to speak on the Puʻu ʻŌʻō crater floor early Wednesday morning.


June 27 lava flow activity is still going, according to HVO observations. Tthe most distant breakout is still about 5 miles northeast of the Puʻu ʻŌʻō crater. Additional surface flows, which experts say are being fed from the breakout that began on Feb. 21, are located about 2 miles from the northeast area of Puʻu ʻŌʻō.
