A new fissure eruption in September 2011 on the east flank of Pu‘u ‘Ō‘ō on Kīlauea Volcano's east rift zone reminds us of the need to be aware of our ever-changing volcanic environment on Hawai‘i Island. The fissure—the source of the lava flow—is shown in this image. Pu‘u ‘Ō‘ō cone and crater are in the background. Aerial view is to the southwest.

It is very unusual for large (400 ft) vessels to be so close together during normal science operations.  In this case, the skilled ship handling of the Captain from USCGC Healy enabled Healy to back within ~75 ft of Louis to clear ice around the bow of Louis, thereby releasing pressure and allowing her to move again.
