New eruption at Kilauea's lower east rift zone in the Leilani Estates subdivision in the lower East Rift Zone of Kīlauea Volcano. White, hot vapor and blue fume emanated from an area of cracking in the eastern part of the subdivision. Spatter began erupting shortly before 5:00 p.m. HST. Lava was confirmed at the surface in the eastern end of the subdivision, in the areas of Mohala and Leilani Streets. According to the Hawai‘i County Civil Defense update at 5:40 p.m., all residents in Leilani Estates and Lanipuna Gardens Subdivsions are required to evacuate.(image: HVO/USGS)

Kilauea (Hawai'i): (4 May) Yesterday's eruption in the Leilani Estates subdivision in the lower East Rift Zone of Kīlauea Volcano only lasted about 2 hours and already ended by about 18:30 local time. Only small amounts of lava were erupted and produced flows that advanced less than 10 m from the fissure.
"At this time, the fissure is not erupting lava and no other fissures have erupted", HVO reports, but this brief episode is likely only the beginning of something else: seismic activity continues to be elevated, indicating that magma is still on the move. As well, the summit caldera continues to deflate, i.e. magma is draining from the summit reservoir into the rift. Therefore, a rather likely scenario is that new and potentially larger eruptions in similar or other areas of the rift zone will occur in a near future.

...4 May:
The expected new rift eruption eruption has begun on Kilauea yesterday afternoon shortly before 17:00 local time (this morning GMT).
Lava emerged from a fissure vent about 150 m long inside a forest in the Leilani Estates subdivision (lower East Rift Zone of Kilauea volcano), in the area where already yesterday new ground cracks had been observed. This means that the magma which had been migrating from underneath Pu'u 'O'o cone (whose floor collapsed as consequence) during the past 3 days since the intrusion had started on 30 April afternoon, has traveled approximately 20 km downrift during 72 hours.

...4 May:
Following a brief pause after the first outbreak reported earlier, at least 3 more eruptive fissures have opened in the same area (Leilani Estates subdivision), apparently over night.
HVO reported this morning (Hawaiian local time) that "at this time, activity consists mostly of vigorous lava spattering. Additional outbreaks in the area are likely. Deflationary tilt at the summit of the volcano continues and the lava lake level continues to drop."
