Location Taken: Kīlauea Volcano, HI, US


Good morning the update for Kīlauea Volcano today is that activity continues at both the summit and the lower east rift zone. The lower east rift zone lave flows are issuing from six fissures.  The fissures have generally moved from the east back to the west.  They’re now in the western edge of the Leilani Estates subdivision and the lava flows are moving very vigorously to the south to produce an ocean entry. The ocean entry is making its way toward the west and there is still a laze plume at the ocean entry that will exist as long as there is an ocean entry.  The laze plume is something that was there even when Puʻu ʻŌʻō was producing lava flows in tube systems of lava that went into the ocean.


Moving towards the summit the activity is producing explosions that happen about two times a day that produce ash up to between 8,000 and 10,000 feet above sea level and there are several minor explosions that occur intermixed with those larger explosions during the day.  The larger explosions are going to produce ash fall that goes downwind so people in communities down wind of the summit will still be seeing ashfall and there’s also still continued deflation and high seismicity in the summit area.  That’s the update for today.
