Great weather conditions allowed us to fly over Pu‘u ‘O‘o crater, getting good peek at the boiling lake of lava within. Bubbling occurred along its perimeter as thick clouds of sulfur dioxide rose around it. Numerous little nosebleed breakouts were observed on the upper flow field within a mile of the vent, while a few more were seen above Pulama Pali, but the most vigorous surface activity was seen on the coastal plain near the base of Pulama Pali. The distal tip also continues to advance, albeit slowly, and has covered approximately 1/3 of the distance to the emergency access road. Lastly, lava continues to pour into the sea at Kamokuna, adding area to the growing delta of land. A few of the stress fractures have been covered by surface activity, but the exposed ones continue to grow in width.
