Initial reports indicate no impact to Kīlauea following earthquakes in East Hawai‘i
According to officials at Hawaiian Volcano Observatory, the quakes weren’t magma-related. More information will be provided as it becomes available.
Scientists walk inside Big Island volcano as earthquake numbers inch up slightly
With the assistance of a helicopter, the Hawaiian Volcano Observatory scientists are working to upgrade a sesimic monitoring station on hardened black lava covering the crater floor near Uēaloha (Byron Ledge) of Kīlauea.
Volcano Watch: More shaking on Kīlauea’s south flank; did you feel it?
From subtle shakes that feel like wind to abrupt jolting that knocks dishes off the counter, living on this volcanically active island means accepting that the ground beneath our feet will not always keep still.
No signs of imminent eruption at Kīlauea despite continued unrest, experts say
According to HVO’s report Tuesday morning, the unrest is primarily in the form of intermittent low-frequency energy signals typical of magma movement. The number of individual earthquakes remained low, with less than 10 events detected.
Conversation about Big Island’s official name sparks minor moniker controversy
The Hawai‘i Board of Geographic Names during its April 2 meeting began a discussion about possibly changing the island’s official name in the U.S. Geological Survey’s Geographic Names Information System, or GNIS.
County Council to consider proposed lower Puna water study examining possible health impacts of geothermal operations
The study aims to build on previous assessments by sampling more sites and conducting more analysis throughout its duration.
Volcano Watch: Kīlauea intrusion was a textbook example of dike propagation
Dike intrusion is one of the fundamental processes for magma migration at volcanoes around the world.
Volcano Watch: Dear Valentine, will you be my lab partner?
The U.S. Geological Survey Hawaiian Volcano Observatory “lavas” working with our partners at the University of Hawai‘i at Hilo, and for Valentine’s Day we wanted to highlight some of the things we appreciate about this relationship.
Hawai‘i Volcanoes National Park releases February flight operations
Management of the park requires using aircraft to monitor and research volcanic activity, conduct search-and-rescue missions and law enforcement operations, support management of natural and cultural resources and maintain backcountry facilities.
Volcano Watch — Where is magma stored in Kīlauea?
At Kīlauea, there are several storage regions hypothesized from decades of monitoring data.
Volcano Watch — New Year’s Eve 1974: Kīlauea’s most recent Southwest Rift Zone eruption
HVO continues to monitor unrest in the summit and Southwest Rift Zone regions of Kīlauea, with increased rates of earthquakes and ground deformation indicating magma is moving in the area
Volcano Watch: A pupu platter of earthquakes
Thousands of earthquakes occur every year in Hawaiʻi. These earthquakes are monitored by the U.S. Geological Survey Hawaiian Volcano Observatory and fall into three main classes: volcanic, tectonic and mantle.
Volcano Watch: Sniffing out stealthy gas escape between Kīlauea’s eruptions
There is another type of gas besides sulfur dioxide that can be important during non-eruptive periods — carbon dioxide.
Volcano Watch: Volcano monitoring can be a risky business: How scientists work safely
Most of HVO’s field sites are more than one hour from definitive medical care, so staff take Wilderness First Aid training which prepares them for a variety of injuries and illnesses.
Volcano Watch: Unrest continues at Kīlauea Summit
A series of earthquake swarms began suddenly at Kīlauea’s summit on October 4, 2023.

The U.S. Geological Survey’s Hawaiian Volcano Observatory said Sunday’s eruption at the Kīlauea volcano includes a line of fissures that stretches approximately 0.8 miles from the eastern part of Halema‘uma‘u crater floor, extending into the east wall of the downdropped block.
Volcano Watch: Tilt measurements still vital to volcano monitoring after more than a century
Tilt data was the first geodetic data collected by the Hawaiian Volcano Observatory (HVO) and continues to be incredibly important both for monitoring and basic research in volcano behavior.
Small, brief earthquake swarm rattles at Kīlauea summit this morning
The volcano has shown signs of elevated unrest with steady rates of earthquakes since Aug. 22.
