Volcano Watch — Eruption? Intrusion? What’s the difference?

We know that when a volcano erupts, molten red rock makes it to the surface, while during an intrusion it doesn’t. The difference between the two processes, if we depend on seismicity (earth shaking) or deformation (changes in ground surface) instrumentation, is not obvious. The events during the start of either are identical.  But we can’t be certain that an intrusion will lead to an eruption...

USGS HVO Kīlauea Status Report — Ground deformation and earthquake activity continues beneath Kīlauea summit region, Island of Hawai‘i

Ground deformation in Kīlauea’s south summit region continues, though at a lower rate than what has been seen in earlier intrusive pulses over the past week. Current earthquake activity remains low compared to the earlier pulses of this intrusive activity. The East Rift Zone remains quiet.

USGS HVO Kīlauea Status Report — Ground deformation and earthquake activity continues beneath Kīlauea summit region, Island of Hawai‘i

Ground deformation in Kīlauea’s south summit region continues, though at a rate slightly lower than the rates seen in the first intrusive pulse spanning August 23-25. In contrast, current earthquake activity remains low compared to the earlier pulses of this intrusive activity. The East Rift Zone remains quiet.

USGS HVO Kīlauea Status Report — Ground deformation and earthquake activity continues beneath Kīlauea summit region, Island of Hawai‘i

Kīlauea volcano is not erupting. However, intrusive activity that began on August 23 continues south of Kīlauea caldera. Starting on the evening of August 26, ground deformation in Kīlauea’s south summit region resumed at the higher rates seen in the first intrusive pulse spanning August 23-25.

USGS HVO Information Statement —HVO Kilauea YELLOW/ADVISORY - Renewed earthquake and deformation activity at Kīlauea summit region, Island of Hawai‘i

The US Geological Survey’s Hawaiian Volcano Observatory (HVO) detected a resumption in earthquake activity and ground deformation beneath the south part of Kīlauea summit caldera, within Hawaiʻi Volcanoes National Park.

Volcano Watch — New Kīlauea Summit Intrusion Draws Comparison to Past Activity

Late Monday afternoon, earthquake activity picked up at Kīlauea’s summit.  At about 1:30 a.m. HST on Tuesday, that activity intensified, and it became clear that seismicity and increasing deformation were indicating a new intrusion of magma.  The seismicity extended southward from Hālemaʻumaʻu crater, to an area south of Kīlauea caldera.

USGS HVO Volcanic Activity Notice — Kīlauea ORANGE/WATCH status change to YELLOW/ADVISORY

The U.S. Geological Survey’s Hawaiian Volcano Observatory is lowering the Volcano Alert Level/Aviation Color Code for Kīlauea from WATCH/ORANGE to ADVISORY/YELLOW reflecting this decrease in activity levels.

USGS HVO Information Statement —Potential for Kīlauea volcano eruption diminished, Island of Hawai‘i

Kīlauea volcano is not erupting. Over the past 24 hours, earthquake activity and ground deformation levels have decreased in the area beneath the southern part of Kīlauea’s summit caldera within the closed area of Hawaiʻi Volcanoes National Park. These observations indicate that the immediate potential for an eruption is diminished at this time.
