(BIVN) – Scientists have confirmed another delta collapse has occurred at the Kamokuna lava ocean entry along the cliffs of Hawaii Volcanoes National Park.
“On May 3, the front section of the Kamokuna lava delta collapsed into the sea,” the USGS Hawaiian Volcano Observatory wrote today, saying it is “a reminder that new land created by ocean entries is highly unstable and prone to collapse without warning.”
One of the first to report the delta collapse was Captain Shane Turpin aboard the Lava Ocean Tours boat. Turpin shared some before and after video, as well as some photos of the lava flow taken just before the collapse (see image above).
By land, John Tarson of Epic Lava Tours also reported seeing changes on the delta during recent trips to the ocean entry.
HVO scientists were out on the flow field today to observe the changes firsthand. UPDATE: USGS uploaded these photos captured by a time-lapse camera. The sequence of events was recorded in five-minute intervals.
The episode 61g flow is still active, USGS says. The lava is entering the ocean, and was slowly building a lava delta at Kamokuna. The flows pose no threat to nearby communities at this time.
On May 3, the USGS produced this new map showing recent activity on the flow field.
