Activity at Pu‘u ‘Ō‘ō and on the 61g flow...

Detailed Description

The lava pond in the west pit of Pu‘u ‘Ō‘ō remains active. While at Pu‘u ‘Ō‘ō making observations, HVO geologists witnessed a small rockfall from the western wall (center right of photo where spattering is occurring). The rockfall briefly disturbed the pond surface and produced spattering for several minutes. Rockfalls into the lava pond are fairly common because the unstable west pit rim and walls have many loose altered rocks, overhung ledges, and cracks (example at left center).
