(BIVN) – Changes at Pu‘u ‘Ō‘ō on the East Rift Zone of Kīlauea Volcano were recently documented by the USGS Hawaiian Volcano Observatory.

Although there are no significant changes in the summit or East Rift Zone eruptions, scientists charted some minor alterations to the 61g lava flow during a November 22 overflight.

There was no lava entering the ocean, nor breakouts on the delta. The USGS reported that the tiny tube breakout that started over the weekend, approximately half a mile from the emergency road, was weakly active Tuesday.

Closer to the base of the pali, scientists say there were more active surface flows, as well as on and above the pali.

No significant changes were noted today at Puʻu ʻŌʻō. Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from a small lava pond on the west side of the crater, USGS said on Friday. Low rates of seismic activity and ground surface deformations are noted. The sulfur dioxide emission rate from the East Rift Zone vents has been steady over the past several months and remains significantly lower than the summit emission rate.

Two new maps were posted to the USGS HVO website on Friday, encapsulating the widening of the lava flow at its borders. A thermal map shows were the breakouts are on top the 61g flow field.
