HAWAII VOLCANOES NATIONAL PARK, Hawaii – The selection of images above shows activity at the northeast spatter cone in Puʻu ʻŌʻō over the past two weeks.
An inexpensive time-lapse camera (whose plastic housing was warped by the extreme heat) captured the sequence of images.
According to the USGS Hawaiian Volcano Observatory, the lava pond was undergoing gas pistoning, a gradual buildup and release of gas in the lava pond that is often associated with spattering and lava level changes.
For scale, the lava pond is about 30 feet across.
