The farthest east fissure is near the margin of downdropped block that formed during the 2018 summit collapse.

A NEW SUMMIT ERUPTION at Kīlauea, with a Warning Alert Level issued by USGS and new vog coming from the Volcano, began on Sunday afternoon, Sept. 10 at about 3:15 p.m. The main fountain, which HVO geologists estimated at approximately 50 meters tall, was on the eastern margin of Halemaʻumaʻu crater. As of approximately 4:30 p.m. HST, the fissures extended
approximately 1350 meters to the northeast, onto the downdropped block that formed during the 2018 summit collapse.
The eruption also carried with it an increase in sulfur gas emissions, which built slowly after 6 p.m. on Sunday to reach a level at 10 p.m. in Pāhala, measured by the state Department of Health, to be Unhealthy for Sensitive People.
Hawai‘i Volcanoes National Park posted: "Kīlauea began erupting this afternoon, serving as a solemn reminder of the sacredness ingrained in this landscape, symbolizing the presence of the akua, the spiritual forces of Hawaiʻi.

The privilege to witness the creative forces of a new eruption comes with a responsibility to approach this place with reverence.
"We implore all visitors heading to the area to exercise the highest level of respect. While eruptions can spark excitement, it is imperative that observation occurs in silence, allowing the eruption's voice to reach you. Native Hawaiian cultural practitioners, who honor the legacy of this land, deserve unreserved respect for their customs."
The last eruption ended in June without damage to life or property. The 2018 eruption saw lava destroying more than 700 homes in Puna and sending ash fall and poor air quality in all directions.
With the new eruption, an increase in sulphur in the air began again this Sunday. At 9:15 p.m. Sunday, the Hawai‘i Volcanoes National Park air quality map showed good air quality at all of its monitors with the emissions going downslope from Halema‘uma‘u, south to the ocean, away from populated areas. However, the vog built up in Pāhala and by 10 p.m. was Unhealthy for Sensitive People. In the coming days, winds are expected to continue to push the vog southwest into Kaʻū.

Dr. Steven Hess will explain that the terrestrial biota of the Central Pacific is primarily defined by its degree of isolation. "At the center are the Hawaiian Islands, almost 4,000 km (2,480 miles) from the closest continental land mass. Millions of years of evolutionary isolation created beautiful and unique native ecosystems," says the invitation to the event. "However, the Central Pacific islands were suddenly besieged by alien rodents, carnivores, ungulates, reptiles and diseases."
