Vigorous degassing of sulfur dioxide, nighttime glow and intermittent lava spattering in the north vent indicate that magma is close to the surface of Kīlauea.

Health officials encourage the public to keep a close eye on Hawaiʻi air quality data as volcanic gas emissions remain elevated. Air quality can change quickly, depending on the amount of gas being released from the Big Island volcano, wind direction and other weather conditions.

Newest eruptive activity of ongoing eruption of Big Island volcano began just before 6:30 p.m. Tuesday, with lava fountaining to more than 200 feet about 30 minutes later.

The latest eruptive activity started at 8:22 p.m. Feb. 19 and ended at 9:18 a.m. Feb. 20. Lava flows from this episode covered 73% of the Halemaʻumaʻu Crater floor in the southern part of Kaluapele, the volcano’s caldera.

Hawaiian Volcano Observatory reports that at about 3 p.m. today, tilt at the summit stopped showing deflation and seismic tremor began decreasing. By 3:30 p.m., lava fountains were barely visible, and by 4 p.m. fountaining had stopped and seismic tremor was close to background levels. Visible volcanic gas emissions also decreased significantly.

The eruption of Kīlauea near Nāpau Crater in Hawaiʻi Volcanoes National Park continues, with lava currently cascading into Nāpau Crater on the northwest rim, according to the Hawaiian Volcano Observatory. Webcam and GOES satellite thermal imagery show that eruptive activity within Nāpau Crater, which had been waning throughout the day, has likely ceased while eruptive […]

While the business district of Pāhoa came dangerously close to being devoured by lave during the 2018 Kīlauea eruption, it was spared. But the town and its people were left reeling. Five residents talk about life then and now.

Kīlauea’s activity from 2018 until 2023 has been compared to cycles of summit collapse and refilling of lava prior to 1924, but it also exhibited similar behavior during the 1967-68 Halema‘uma‘u eruption.

In the latest Volcano Watch, Hawaiian Volcano Observatory scientists are looking for a new place to put a summit gas measuring station to replace the one destroyed by the 2022 Mauna Loa eruption.

Kīlauea erupted on June 7, 2023 at 4:44 a.m. on Hawaiʻi Island. The volcano put on quite the spectacular lava show duing the first day of this eruption. Check out the video and slideshow.

Despite the development of new volcano monitoring techniques, decades between the eruptions meant there were many uncertainties leading to the recent eruption of Mauna Loa on the Big Island.

To find out if magma is accumulating in the magma reservoir of the Big Island volcano Kīlauea, scientists use microgravity surveys.

Activity from the latest Kīlauea eruption is concentrated in a large lava lake in the eastern half of the summit crater and a smaller lake to the west.

This new Kīlauea eruption is viewable from almost all open areas around the caldera in Hawaiian Volcanoes National Park, but there are some parts of the park that are closed to protect breeding and nesting nēnē.

The earthquake was at a depth of 12 miles below sea level; and it occurred in a region of stress interaction between Mauna Loa and Kīlauea volcanoes.

Seismicity and deformation patterns remain unsettled, which means there remains a potential the KIlauea eruption will resume or a new eruption can occur at or near the summit of Kīlauea. But it is unexpected Mauna Loa’s eruption will resume.

There’s a whole lot of warning going on when no warnings have been issued.

An earthquake struck beneath the south flank of Kīlauea on Sunday, May 23.

The rise of the lava lake has been interrupted by several plateaus, and even drops, in level over the past few weeks.
