Kilauea volcano update: East Rift Zone eruption update: fissure eruption sustains lava flows and ocean entries
Eruption of lava continues in the area of Leilani Estates and Lanipuna Gardens, at the lower part of Kilauea’s East Rift Zone. On Saturday morning 26 May (local time) HVO/USGS report that fissure 22 continues to erupt lava that is flowing southeast to the coast and which feeds the first lava ocean entry. Fountains at fissures 6 and 13 also continue to feed lava into a channel that reaches the coast which formed a second ocean entry a few days ago.
Meanwhile fissures 7 and 21 are feeding a perched lava pond and pāhoehoe flow that has advanced north-eastward covering most of the area between Kaupili and Mohala Streets. The flow front has become an 'A'ā flow and is advancing slowly toward Pahoa Pohoiki Road.
Volcanic gas emissions remain very high from the fissure eruptions as magma continues to be supplied to the lower East Rift Zone. Earthquake activity continues, but earthquake locations have not moved farther down rift in the past few days and the number of located earthquakes remains low.
Kilauea’s summit caldera area was the scene of larger ash explosions and increased seismic activity. Multiple small explosions occurred throughout Friday 25 May which ejected ash plumes to under 3050 m (10,000 ft) above sea level. A larger explosion occurred at 4h17 pm local time which produced and ash plume as high as 3660 m (12,000 ft) above sea level. There were many earthquakes in the summit area during Friday 25 May, with 8 earthquakes greater than M3. The largest of which was M3.99 and located just north of Halema`uma`u crater. Many more small quakes occurred between the larger events. Both earthquakes and ash explosions are occurring as the summit area subsides and adjusts to the withdrawal of magma
