(BIVN) – Volcanic activity on Kilauea volcano’s East Rift Zone continues, and scientists with the USGS Hawaiian Volcano Observatory are documenting it.
On February 10 at 8:21 in the morning, a large portion of the northeastern rim of the west pit in Pu’u O’o collapsed. Prior to and during the rim collapse, the adjacent ground also subsided.
(USGS) On the south rim of Pu‘u ‘Ō‘ō, on Kīlauea’s East Rift Zone, an HVO geologist surrounded by thick steam and gas performs regular upkeep to the west pit time-lapse camera. This camera was relocated again at the end of January due to continued subsidence and instability in its previous location.
There have been several active breakouts and lava channels on the Pulama pali over the past few days.
No lava is flowing into the ocean, and the ongoing flows do not pose any threat to nearby communities at this time.
USGS also produced a new map of the flow field:
(USGS MAP) This map shows recent changes to Kīlauea’s East Rift Zone lava flow field. The area of the active flow field as of January 30, 2018 is shown in pink, while widening and advancement of the active flow as of February 20, 2018 is shown in red. Older Puʻu ʻŌʻō lava flows (1983–2016) are shown in gray. The yellow line is the trace of the active lava tubes.
