Landsat satellites capture images of the Earth’s surface. While the sensors aboard Landsat capture a wide range of scientifically useful wavelengths, this collection reveals natural color imagery in the red, green and blue parts of the visible spectrum, as if viewed by the naked eye from 438 miles above the surface.

On September 19, 2024, USGS-Hawaiian Volcano Observatory geologists landed near the Kīlauea middle East Rift Zone eruption site, where they viewed lava flowing through a channel more than 50 meters (about 164 feet) wide. 

On the night of September 15, USGS Hawaiian Volcano Observatory geophysical data indicated that an eruption could be occurring a remote area of Kīlauea’s middle East Rift Zone, within 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.

USGS Hawaiian Volcano Observatory geologists conducted a reconnaissance overflight of the eruption near Nāpau Crater on the middle East Rift Zone of Kīlauea. They observed lava cascading over the rim of the crater from a channel more than 50 meters (about 164 feet) wide.

On September 19, USGS Hawaiian Volcano Observatory geologists were able to capture this video of the fissure vent eruption west of Nāpau Crater on the middle East Rift Zone of Kīlauea. They observed a 150-m-long (nearly 500 feet) fissure west of the crater erupting lava in a curtain of lava 10-20 meters (33-66 feet) high. 

Kīlauea volcano is erupting in Hawai’i Volcanoes National Park from a new fissure vent that opened within Nāpau Crater this morning, September 17, between 4:00 and 5:00 AM HST.  The eruption is occurring within a closed and remote area of Hawaiʻi Volcanoes National Park.

USGS Hawaiian Volcano Observatory geologists collected a sample of the middle East Rift Zone Kīlauea eruption in Nāpau Crater, within a closed area Hawaiʻi Volcanoes National Park. Geologists put molten lava into a metal bucket and rapidly quench it with water.

A brief, small eruption occurred on the middle East Rift Zone of Kīlauea late on September 15. The eruption produced two small pads of lava just west of Nāpau Crater, which is west (uprift) of the former Pu‘u‘ō‘ō eruption site. 

This video, taken during a Hawaiian Volcano Observatory morning overflight of Kīlaueaʻs middle East Rift Zone on September 16, 2024, shows new lava flows erupted over about an hour during the evening on September 15, 2024.

During a USGS Hawaiian Volcano Observatory overflight at approximately 10:30 a.m. HST on September 16, geologists observed freshly erupted lava west of Nāpau Crater on the remote middle East Rift Zone of Kīlauea, within Hawaiʻi Volcanoes National Park. This eruption likely occurred between approximately 9–10 p.m. HST on September 15.
