The satellite shows the “glow” of lava inside an erupting Hawaiian volcano from space.
Kilauea, Hawaii’s youngest and most active volcano, has been erupting since January 5, and scientists have been able to observe the eruption from space, revealing unique details.
January 11, Landsat 8 captured Kilauea volcano, one of the five volcanoes that make up the Hawaiian Islands in the Pacific Ocean, near Mauna Loa volcano, image of the eruption from space, lava and smoke glowing brightly

The Operational Ground Thermal Imager (OLI) aboard the Landsat 8 satellite acquired a natural color blend composite image to better highlight the infrared thermal signature of the lava.
At the time the image was taken, eruptive activity in the Kilauea caldera was concentrated in a large lava lake in the eastern half of the Halema’uma’u crater, as well as a smaller area of lava in the western half of the crater.
According to NASA’s Earth Observatory, volcanic activity is common in Kilauea and a recent eruption created a lava lake that lasted from September 29, 2021 to December 9, 2022.
“Kilawea erupted almost continuously from 1983 to 2018, when the months-long eruption generated slow-moving lava flows that destroyed about 700 homes,” the observatory said in a statement released Tuesday, January 17.
“Since the eruption of the Kilauea volcano in 2018, it has erupted sporadically. These recent eruptions were localized in the Halemaumau crater in the form of lava lakes,” he added.
NASA indicated that pyroclastic eruptions in the Halemaumau crater reached heights of up to 50 meters (164 feet) during the new explosion, especially in the first hours after the January 5 eruption.
