#Eruption

The current volcanic activity is within the national park boundaries and does not present a threat outside the park. and does not pose a threat outside of the park.

Approximately 65 earthquakes were detected beneath the upper East Rift Zone.

The cracks likely formed due to the intrusion of magma into the Upper East Rift Zone of Kīlauea volcano this week.

The observatory’s tower on the edge of the Kīlauea caldera inside Hawai‘i Volcanoes National Park will be demolished today after work was postponed from Thursday. It is the last remnants of the former observatory and museum complex that was closed after it was damaged beyond repair in 2018 during the 2018 eruption, lava flow and summit eruption of the Big Island volcano.

According to Hawaiian Volcano Observatory, the seismicity and elevated ground deformation rates suggests magma may be slowly moving out of the summit storage region.

Measurement of volcanic gases is critical for both public safety and understanding volcanic activity—and everything we measure relies on the wind.

Their mission was to remove temporary webcams deployed during a recent eruption and move them to nearby Cone Peak.

Over the past 24 hours, there were approximately 25 earthquakes detected beneath Kaluapele (Kīlauea caldera) and 95 earthquakes detected beneath the Upper East Rift Zone, mostly at depths of 0.6–1.8 miles beneath the ground surface.

Over the past day, the seismic activity has moved closer to the summit between Keanakākoʻi and Koʻokoʻolau craters in Hawaiʻi Volcanoes National Park.

While there are no signs of an imminent eruption, the largest of these earthquakes were four magnitude-3.0 events near the intersection between Chain of Craters Road and Hilina Pali Road in Hawaiʻi Volcanoes National Park.

Ed was a natural and gifted problem solver, and he worked closely with observatory staff to understand their challenges and needs.

The volcano erupted on June 3 in the remote upper Southwest Rift Zone. Kīlauea spewed lava for 8.5 hours before stopping again. The last eruption occurred in September 2023.

Maunaiki Trail and Kaʻū Desert Trail past the Footprints Exhibit remain closed due to elevated gases and other volcanic hazards that remain at the eruption site.

The USGS Hawaiian Volcano Observatory is lowering the Volcano Alert Level for ground-based hazards from WATCH to ADVISORY and the Aviation Color Code from ORANGE to YELLOW.

While there is no active lava on the surface, Hawaiian Volcano Observatory reports that levels of unrest remain high as the vent remains open, tremor is still present, glow could still be seen from the fissures overnight and active degassing of SO2 is still occurring from the fissures and blowing downwind.

While the lava flow has ceased, air quality levels are slightly elevated at the Pāhala and Nāʻālehu air quality monitoring stations.

The most recent Mauna Loa eruptions in 1975, 1984, and 2022 each offer unique insights into this volcano’s eruptive behavior.

One of the primary duties of IT personnel at HVO is supporting existing and emerging volcano monitoring and science goals. The observatory uses a variety of instruments to collect data on volcanic activity—including seismometers, gas analyzers, ground deformation sensors, and cameras.

Earthquakes are clustered in the upper East Rift Zone as well as the south caldera region.

Since midnight of April 27, over 1,600 earthquake events have been recorded on Kīlauea on the Big Island.
