Over the past two weeks, many DI pressure cycles have dominated the style of eruptive activity on Kīlauea volcano, influencing the location of coastal lava flows to be closer to the ocean or to the hillside with more and less pressure respectively. Active lava flows have been accessible over private land every day except one since our last update, and during higher pressure stands the activity has often put lava just inside the National Park boundary close to the ocean. During higher pressure days, lava flows often also break out on the lower part of the hillside and can be seen from a great distance from specific points within the National Park.

Despite smaller-scale pressure cycles on Kīlauea volcano, recorded as a series of 1-2 microradian deflation-inflation events at the summit, lava levels have remained high with lots of activity for visitors to experience up close or from a distance! Glow visible from the Jaggar Overlook of the newest summit crater, the Overlook Vent, continues to be spectacularly bright during the evening hours, and lava flows continue to be active on the coast and are even visible from a distance on clear nights, better from the National Park side (as shown by the USGS Hōlei Pali Mobile Cam 4).
