New research highlights the far-reaching impact of the 2022 Tonga eruption, extending from Earth’s surface to the edge of space and posing risks to critical satellite infrastructure.
Volcanic Shockwaves Reached Space After Tonga Eruption
The cataclysmic eruption of the Hunga tonga-Hunga Ha‘apai volcano in January 2022 wasn’t just a terrestrial event; its effects reverberated far beyond Earth’s surface, impacting the very edge of space. “When the Hunga Tonga-Hunga Ha‘apai volcano blew its top in 2022, it wasn’t just one of the most powerful eruptions in modern history—it literally made waves in space,” scientists have confirmed.
The sheer force of the explosion propelled ash and gas to staggering heights. “The explosion sent a towering plume of ash and gas over 31 miles (50 kilometers) into the atmosphere, punching far above where commercial jets cruise and most weather lives.” But the true surprise lay in the eruption’s extended reach.
Secondary Gravity waves: The Unseen Culprit
A new study published in AGU Advances sheds light on how this underwater volcano managed to influence regions far beyond its immediate vicinity. “A new study published in AGU advances explains how the gargantuan eruption managed to rattle a part of the planet most volcanoes never touch.” By analyzing satellite data and employing elegant atmospheric modeling, researchers pinpointed the mechanism behind this phenomenon: secondary gravity waves.
the study considered two possible causes: lamb waves, which are pressure waves that travel along the Earth’s surface, and secondary gravity waves, which are generated when the initial waves break apart at high altitudes. “Using satellite data and atmospheric modeling, the researchers tested two culprits: lamb waves—pressure waves that “hug” Earth’s surface—and secondary gravity waves, which are generated when the frist wave of, uh, waves, break apart high in the sky.”
Ultimately,the evidence pointed to the latter. “The researchers found that the secondary gravity waves were the culprit, as their fast movements and larger magnitudes better matched the satellite data studied by the team. Basically, the Tongan eruption created a shockwave so intense it shook the sky.” These findings underscore the interconnectedness of Earth’s systems, demonstrating how events on the surface can have profound effects on the upper atmosphere.
Early Warning Signs: A missed Prospect?
The study adds to a growing body of knowledge about the Tonga eruption, with potentially important implications for disaster preparedness. “The findings complement earlier research showing that the Hunga Tonga-Hunga Haʻapai eruption gave off a subtle seismic signature—a Rayleigh wave—before the eruption began, detectable by seismometers over 400 miles (644 km) away.” This previously overlooked seismic signal could have served as an early warning, potentially mitigating some of the eruption’s impact.
“That wave—imperceptible to humans—was a rare and overlooked clue that somthing catastrophic was about to happen. Together, these studies suggest that massive volcanic events don’t just shake the ground—they shake the entire atmosphere, from the seafloor to the edge of space. Now scientists are realizing that earth’s most violent eruptions might leave multiple early fingerprints—if we certainly know where (and when) to look.”
Implications for Satellites and U.S. Infrastructure
The research underscores the vulnerability of critical infrastructure to extreme natural events. “The team’s study is also a reminder that what happens on Earth’s surface can even perturb the edge of space—a zone we increasingly rely on for communication, weather tracking and climate modeling, and GPS.” This is particularly relevant to the United States, which relies heavily on satellite technology for everything from national defense to everyday navigation.
Understanding these impacts is crucial for protecting our satellite infrastructure. “The better we understand how events like this ripple out from their sources, the better we can protect the tech we depend on to function down here.” The potential for disruption to GPS, communication networks, and weather forecasting poses a significant threat to national security and economic stability.
| Satellite Service | U.S. Sector Impacted | Potential Disruption |
|---|---|---|
| GPS | Transportation, Agriculture, Emergency Services | Navigation errors, precision farming disruptions, delayed emergency response |
| Communication Satellites | Telecommunications, Media, Finance | Communication blackouts, disrupted broadcasts, financial transaction delays |
| Weather Satellites | Agriculture, aviation, Disaster Management | Inaccurate weather forecasts, compromised crop yields, inadequate disaster warnings |
Counterargument: are Space Weather Events Overhyped?
Some argue that the threat posed by space weather events, including those triggered by volcanic eruptions, is overblown. They contend that satellite technology is becoming increasingly resilient and that the economic impact of past events has been relatively minor. though, this argument fails to account for the growing reliance on satellite services and the potential for cascading failures. While satellites are becoming more robust, the complexity of modern systems means that even minor disruptions can have far-reaching consequences. Furthermore, the economic impact of a major, sustained outage could be catastrophic, far exceeding the costs of preventative measures.
FAQ: Understanding the Tonga Eruption’s Impact
- how did the tonga volcano eruption affect space?
- The eruption generated powerful secondary gravity waves that traveled into the upper atmosphere, reaching the altitudes where satellites orbit. These waves can disrupt satellite communications and GPS signals.
- What are secondary gravity waves?
- Secondary gravity waves are atmospheric disturbances created when initial pressure waves from an event like a volcanic eruption break apart at high altitudes. “The researchers found that the secondary gravity waves were the culprit, as their fast movements and larger magnitudes better matched the satellite data studied by the team.”
- Why are scientists concerned about volcanic eruptions affecting satellites?
- Because “what happens on Earth’s surface can even perturb the edge of space—a zone we increasingly rely on for communication, weather tracking and climate modeling, and GPS.” Disruptions to these services can have significant economic and societal consequences.
- Could the Tonga eruption have been predicted?
- Possibly. “the findings complement earlier research showing that the Hunga Tonga-Hunga Haʻapai eruption gave off a subtle seismic signature—a Rayleigh wave—before the eruption began, detectable by seismometers over 400 miles (644 km) away.” Enhanced monitoring and analysis of seismic data could improve early warning systems.
- What can be done to protect satellites from future events?
- Improving satellite design to withstand space weather events, developing backup communication systems, and enhancing monitoring of volcanic activity and atmospheric conditions are all crucial steps.

Interview: Dr. Aris Thorne on the tonga volcano Eruption and its Impact on Satellites
Archyde news –
The 2022 Tonga volcano eruption sent shockwaves not just across the globe but also into space, impacting critical satellite infrastructure. To discuss the far-reaching consequences, we have Dr. Aris Thorne, a leading expert in atmospheric physics at the Global Space Institute.
Welcome, Dr. Thorne.Thanks for joining us. Can you give us a brief overview of how the Tonga eruption managed to influence the upper atmosphere?
Dr. Thorne: Thank you for having me. The eruption of Hunga Tonga-Hunga Ha‘apai was incredibly powerful.It generated massive pressure waves that traveled through the atmosphere. These initial waves, called Lamb waves, broke apart high in the atmosphere, creating secondary gravity waves. These secondary gravity waves were the key. They were so intense that they caused disruptions in the ionosphere, which is a critical region for satellite operations.
The study mentions the importance of secondary gravity waves. Can you elaborate on their importance in this context?
Dr. Thorne: Absolutely. Secondary gravity waves,formed at very high altitudes,were found to match the satellite data more closely,with high magnitudes and faster movements. that means this eruption shook the very edge of space. They’re not something we normally consider a major influence on space weather, making this eruption especially notable. These waves are the direct link between the eruption and the disruption of the ionosphere.
In the article, it’s mentioned that the eruption also provided a “Rayleigh wave.” Could that have provided an Early Warning?
Dr. Thorne: Yes, it appears so. The initial seismic activity,a Rayleigh wave,was an overlooked clue that something catastrophic was imminent. By analyzing that we could have gained a good amount of time before the actual event.
How does this research impact fields like communications, national security, and, more broadly, our global infrastructure?
dr. Thorne: We rely so heavily on satellite technology now.GPS for navigation, dialog satellites for global connectivity, and weather satellites for forecasts—they are all vulnerable to these space weather events. Any disruption could have important economic and societal consequences, ranging from travel delays to challenges in financial transactions to even national security concerns. Our increasing dependence on satellite systems makes them a major target for future space weather-related issues.
What specific steps can be taken to mitigate the risks to satellite and space infrastructure?
Dr. Thorne: We need a multi-pronged approach. This includes improving satellite design to withstand space weather events, developing and deploying backup communication systems like terrestrial networks, and enhancing our monitoring capabilities for both volcanic activity and atmospheric conditions. We may even need to update the satellite operation protocols to make the satellites more resilient.
The article mentions a counterargument about the threat posed by space weather events being “overblown”. What is your response to this argument, especially concerning the Tonga eruption?
Dr. Thorne: Such a claim ignores the increasing reliance on satellite services and potential cascading failures. While satellites themselves are becoming more robust, modern systems are incredibly complex. Even minor disruptions can have far-reaching effects. The economic impacts of a major, sustained outage could be catastrophic, far exceeding the costs of preventative measures. Furthermore, a large eruption could cripple infrastructure more then we see now.
regarding the potential for predicting such events,do you see enhanced monitoring and analysis of seismic data playing a greater role in the future?
Dr. Thorne: Absolutely. Enhanced monitoring is critical. We’ve seen that there can be subtle early warning signs. By improving our ability to detect and interpret these subtle signals, we can develop early warning systems. This would provide valuable time to protect our critical infrastructure and prepare for potential disruptions.
Dr. Thorne, thank you for sharing your expertise with us. Our readers are always looking for ways they can prepare for such events.Do you have any advice for protecting our infrastructure?
Dr. Thorne: Of course. It’s always wise to have a plan for potential disruptions. This includes backup communications, like HAM radio and other emergency services. It also includes staying informed about potential threats, and supporting the research that is helping us better understand and predict space weather events. Knowledge is always the best defense.
what is the single most critically important takeaway from the Tonga eruption research for your field?
Dr. Thorne: The most important takeaway is the interconnectedness of Earth’s systems; what happens on the surface can dramatically impact space. We rely on the space environment more than ever, and we need to protect it. The eruption taught us that we need to be ready for the unexpected.
Thank you for your time and expert insights, Dr. Thorne.
Dr.Thorne: My pleasure.
