Is Kīlauea poised to erupt again, or is this just a temporary lull? The U.S. Geological Survey (USGS) is keeping a close watch, and here’s what thay’re seeing. The recent activity, while paused, doesn’t meen the story is over. Fissure eruptions can be deceptive, taking breaks before roaring back to life [[2]].
The Recent Eruption: A Recap
Early Monday morning, the southwest end of the Kīlauea caldera within Hawaiʻi Volcanoes National Park became the stage for the latest eruption [[2]]. But what made this eruption unique?
A Blast from the Past: Old Eruptive Styles Return
The eruption within Halemaʻumaʻu showcased an eruptive style unseen for many years, featuring three distinct episodes of lava fountaining, each separated by pauses [[3]]. It’s like watching a classic rock band dust off some deep cuts – familiar, yet excitingly different.
What the Scientists Are Saying
USGS Hawaiian Volcano Observatory scientists are meticulously analyzing past eruption patterns and current monitoring data to predict Kīlauea’s next move [[3]]. It’s a bit like being a meteorologist, but rather of predicting rain, they’re forecasting lava.
The Pressure is On: Magma Supply and Future Activity
Continued magma supply suggests that future intrusive episodes and eruptions are possible [[1]]. Think of it like a shaken soda bottle – eventually, it’s going to pop. The question is, when and how big?
Sulfur Dioxide: A Key Indicator
On September 17, the sulfur dioxide emission rate at the summit was measured at 60 tonnes per day [[1]]. This is a crucial metric. Why?
Why Sulfur Dioxide Matters
Sulfur dioxide (SO2) is a volcanic gas. Changes in its emission rate can indicate changes in magma activity beneath the surface. A sudden increase could signal an impending eruption. It’s like a volcano’s way of clearing its throat before singing a fiery song.
The Unlikely, But Possible: What Could Happen Next?
While the USGS states that an immediate eruption is unlikely, the possibility remains [[2]]. Here’s a breakdown of potential scenarios:
Scenario 1: The Fissure Awakens
Fissure eruptions can restart after hours or even days of inactivity [[2]]. This could mean a sudden resumption of lava flow in the same area as the recent eruption.
Scenario 2: A New Location
Magma could find a new path to the surface, leading to an eruption in a different part of the Kīlauea caldera or even along the East Rift Zone [[1]]. This is less predictable and could pose new challenges for monitoring and response.
Scenario 3: Continued Intrusions
Magma might continue to intrude beneath the surface without erupting, leading to ground deformation and increased seismic activity.This could be a prolonged period of unrest, similar to what preceded the 2018 eruption.
Living with a volcano: What It Means for Hawaiians
Kīlauea is more than just a geological feature; it’s a part of Hawaiian culture and identity. Living near an active volcano requires respect,preparedness,and a deep understanding of the risks.
The Cultural Significance
In Hawaiian tradition, volcanoes are sacred places, home to the goddess Pele. Eruptions are seen as both destructive and creative forces, reshaping the land and renewing life.
Preparedness is key
For residents of the Big Island, being prepared for volcanic activity is a way of life. This includes having emergency plans, staying informed about potential hazards, and respecting the power of nature.

Kīlauea Volcano: Is Hawaii’s Sleeping Giant About to awaken Again? A Q&A with Volcanologist Dr. Aris Thorne
Keywords: Kīlauea volcano, volcanic eruption, Hawaii, USGS, sulfur dioxide, volcano preparedness, Halemaʻumaʻu
Time.news: dr.Thorne, thank you for joining us today. The recent pause in activity at Kīlauea has many wondering: Is the volcano truly sleeping, or is this just a temporary respite?
Dr. Aris thorne: Thanks for having me. The situation at Kīlauea is indeed complex. While the recent eruption seemingly ended,the U.S. Geological Survey (USGS) is right to maintain a vigilant watch.Volcanoes, especially fissure eruption volcanoes like Kīlauea, are known for their unpredictable behavior. They can pause for hours or even days before resuming activity, sometimes with renewed intensity.So, no, Kīlauea is certainly not “sleeping” per se. It’s more like it’s taking a breather.
Time.news: This recent eruption within the Halemaʻumaʻu crater was described as a return to older eruptive styles. Can you elaborate on that and why it matters?
Dr. Aris Thorne: Absolutely. We observed three distinct episodes of lava fountaining, separated by pauses.This is significant because it’s a pattern that hasn’t been seen consistently in recent Kīlauea eruptions. It suggests subtle shifts in the magma plumbing system and how the magma interacts with the surface. Understanding these past eruptive styles helps volcanologists refine their predictive models for future activity. Think of it as learning from Kīlauea’s ancient “playbook”.
Time.news: The article mentions that the USGS Hawaiian Volcano Observatory is closely monitoring magma supply and sulfur dioxide emissions. Why are these factors so crucial?
Dr. Aris thorne: Continued magma supply is the fuel for future eruptions. If magma is still being delivered to the shallow reservoir beneath Kīlauea, the pressure will inevitably build up. It’s like a shaken soda bottle – eventually, it’s going to release that pressure, either through intrusive events (where magma stays underground) or through eruptions.
Sulfur dioxide (SO2) is a volcanic gas that escapes from the magma. Changes in SO2 emission rates are an excellent indicator of changes occurring at depth. A sudden increase frequently enough signals that magma is rising closer to the surface, which can be a precursor to an eruption. The measurement on september 17th of 60 tonnes per day is a baseline,but significant fluctuations upwars are what volcanologists are watching for. Think of it as monitoring the volcano’s “breath” – a change indicates something is happening inside.
Time.news: The article outlines three potential scenarios: a fissure reactivation, a new eruption site, or continued magma intrusions. which of these scenarios worries volcanologists the most?
Dr. Aris Thorne: Each scenario presents unique challenges.Fissure reactivations can be dangerous as they can occur with little warning in areas already affected. A new eruption site is even more concerning due to the unpredictable nature around its location and potential flows – these are harder to anticipate and prepare areas for. continued magma intrusion, such as happened before the 2018 eruption. While it may not immediately pose an eruptive threat, it can lead to ground deformation, increased seismic activity, and, ultimately, a larger, more destructive event down the line. Volcanologists closely monitor ground deformation and seismic activity alongside gas emission when judging the situation.
Time.news: The 2018 Kīlauea eruption was devastating. Are there lessons learned from that event that are informing current monitoring and preparedness efforts?
Dr. Aris Thorne: Absolutely. The 2018 eruption highlighted the importance of understanding the East Rift Zone and the potential for flank eruptions that can rapidly impact communities. It emphasized the need for proactive monitoring, effective interaction with the public, and robust emergency response plans. It was a brutal wake-up call, but it also spurred significant improvements in our understanding of Kīlauea and our ability to forecast its behavior.
Time.news: What practical advice can you offer to residents of the Big Island and visitors who are concerned about future eruptions?
Dr. Aris Thorne: The most critically important thing is to stay informed through official channels like the USGS Hawaiian Volcano Observatory (HVO) and local news outlets. Have an emergency plan in place, including evacuation routes, supplies, and communication strategies. respect exclusion zones and heed warnings from authorities. Remember that Kīlauea is a natural force, and living near an active volcano requires preparedness and vigilance. Furthermore, understand the cultural significance of volcanoes within the Hawaiian tradition and approach them with respect. Kīlauea is more than just a geological feature; it’s a vital part of the island’s heritage.
Time.news: Dr. Thorne, thank you for your insights. This has been incredibly informative. We will continue to monitor the situation at Kīlauea and provide updates to our readers.
