By Hawaiian Volcano Observatory September 20, 2024

The middle East Rift Zone eruption of Kīlauea volcano, in a remote area of Hawai’i Volcanoes National Park near Nāpau Crater, paused the morning of September 20, 2024. 

USGS Hawaiian Volcano Observatory field monitoring crews reported minor spattering and small fountains at one end of the vent as of 8:30 a.m. HST on September 20, 2024. By 10 a.m. HST, eruptive activity had paused but the eruptive vents continued to emit volcanic gas and steam. The eruption, which began on the night of September 15, occurred within a closed and remote area of Hawaiʻi Volcanoes National Park.

USGS Hawaiian Volcano Observatory field monitoring crews captured these videos during their visit to Kīlauea middle East Rift Zone eruption site the morning of September 20, 2024. They reported minor spattering and small fountains at one end of the vent at 8:30 a.m. HST. By 10 a.m. HST, eruptive activity had paused but the eruptive vents continued to emit volcanic gas and steam. The eruption, which began on the night of September 15, occurred within a closed and remote area of Hawaiʻi Volcanoes National Park. USGS video by M. Patrick.

Pāhoehoe lava flows paved the floor of Nāpau Crater during the recent eruption on Kīlauea middle East Rift Zone. Pāhoehoe is characterized by smooth, billowy, and ropy surface textures. Recent lava flowed over tephra that previously coated this area of the crater floor. Tephra is a word for cinders and other volcanic products that travel through the air before being deposited on the ground surface. The vegetated areas outside of the crater, above the crater walls, are visible in the background of the photo. USGS photo by M. Patrick.

From the floor of Nāpau Crater, USGS Hawaiian Volcano Observatory geologists observed where recent lava flows covered the trail in the crater. The trail is visible in the lower center portion of the photograph, as a track in tephra deposited during previous eruptions in the area. USGS photo by M. Patrick.

During the September 20 monitoring overflight, USGS Hawaiin Volcano Observatory geologists observed the fissure west of Nāpau Crater reactivate briefly between 8–9:30 a.m. HST, with minor fissure fountaining and lava flows. View is looking southeast. USGS photo by H. Winslow.

A helicopter overflight on September 20, 2024, allowed for aerial visual and thermal imagery to be collected at the middle East Rift Zone eruption site on Kīlauea.  This thermal map shows that the eruption at Nāpau Crater had paused this morning, with no fountaining or active lava on the surface. Shortly after these morning thermal images were collected, a small portion of the fissure system briefly reactivated, but soon died out again. As of this afternoon, the eruption was again in a pause. The scale of the thermal map ranges from blue to red, with blue colors indicative of cooler temperatures and red colors indicative of warmer temperatures.
