HVO field staff were notified and they hurried to the crater rim just before 4:45 a.m. HST, indicating that an eruption was imminent. Kīlauea’s alert level and aviation color code were elevated to WATCH/ORANGE at 3:14 a.m. ![]() With close attention to the data on June 7, HVO scientists were able to identify the precursory activity that closely mirrored previous recent eruptions. Distinct earthquake events are the vertical red spikes in the left side of the plots whereas volcanic tremor is the horizontal red band in the right side of the plots. ![]() The data is shown as spectrograms, which display the energy of seismic events (vertical axis) occurring over time (horizontal axis). Data recorded on June 7, 2023, by five seismometers located in Kīlauea summit region. One hypothesis for why this occurred is the large amount of molten material stored beneath the surface of Halema‘uma‘u crater floor, in combination with the short timeframe following the previous eruption. Rapid earthquake activity occurred for about 30 minutes, followed by an hour of relative seismic silence before lava broke the surface with eruptive tremor. This eruption occurred mere weeks after the previous one had ended in December 2022. Ground motion then begins to deflate, indicating the release of pressure within the magma system.Īn outlier is the onset of the January 2023 eruption at the summit of Kīlauea. Eventually, fountains of lava burst from the ground and a conduit is established volcanic tremor-a signal indicating fluid movement, like the hum of water moving through a garden hose-begins to replace the earthquakes, slowly becoming the dominant signal. These signals indicate that magma is creating a pathway towards the surface. The clearest signals before these recent eruptions are rapidly occurring earthquakes-most not large enough to be felt-as rocks beneath the surface break, along with an increasing rate of inflationary ground motion as pressure builds. In most recent cases, the signs of an imminent eruption become evident only about an hour before the eruption occurs. HVO scientists have noted these periods of “increased unrest,” and they closely monitor the data streams for signals that an eruption may be imminent. USGS image.įor days to months leading up to all eruptions at Kīlauea since 2018, as well as Mauna Loa in 2022, increased earthquake activity and ground inflation suggested that the magma storage systems below were under stress. HVO geologists were in position on the crater rim at Kīlauea volcano’s summit, waiting to observe the eruption start. This photo was taken around 5 a.m., shortly after the eruption started. Lava quickly flooded Halema’uma’u crater floor after the eruption began the morning of June 7, 2023. The eruption marks another in a series of recent eruptions that the Hawaiian Volcano Observatory has been able to successfully forecast. Kīlauea volcano began erupting within Halema‘uma‘u crater at the summit during the early morning of June 7. By US Geological Survey Hawaiian Volcano Observatory scientists and affiliates ![]()
