(BIVN) – Lava from the Kilauea volcano’s episode 61g flow continues to enter the ocean at Kamokuna, scientists say, and intermittent lava flows over the cliff and onto the lava delta, or “lavafalls”, have been reported.
Recent breakouts near the edge of the cliff have been spilling onto the lava delta for the past few weeks, resurfacing almost the entire area of the delta.
From an October 12 USGS Hawaiian Volcano Observatory update:
Today (October 12), the Kamokuna lava delta was measured at roughly 11 acres (4.5 hectares) in size. Over the past two months, several lava tube breakouts on the sea cliff have spilled lava onto the delta. On the delta, ‘A‘ā (darker color) and pāhoehoe (lighter color) flows have resurfaced much of the area in the past few weeks, covering the many surface cracks noted in previous photos. Although the cracks are no longer visible, subsurface cracks still remain, as does the hazard of delta instability. The area directly upslope of the ocean entry is hazardous as well, with ground fracturing and lava tube breakouts occurring over the past few months.
USGS also photographed the lava activity on the upper coastal plain.
The 61g lava flow issues forth from the Puʻu ʻŌʻō vent on the East Rift Zone of the volcano, where low rates of ground deformation and low levels of seismic activity continue.
HVO geologists recently had to relocate a time-lapse camera on the rim of the west pit lava pond in the Pu‘u ‘Ō‘ō crater. Over the past several months, the camera has been slowly tilting downward due to soft, altered ground beneath it, and the general instability of the rim. The new camera location is 20 yards to the south, scientists say, and appears to be more stable and less altered.
These lava flows pose no threat to nearby communities at this time, scientists say.
