Volcanic activity Sparks aviation Concerns Worldwide
Global eruptions prompt ash advisories, impacting air travel and local communities.
Worldwide, several volcanoes are exhibiting increased activity, prompting concerns for aviation safety and potential impacts on local populations. Volcanic Ash Advisory Centers (VAACs) are closely monitoring the situation and issuing warnings as needed.
Indonesia: Multiple Volcanoes Spew Ash
Indonesia, a nation known for its high volcanic activity, is currently facing eruptions from multiple peaks.Mount Ibu on Halmahera Island continues its explosive activity. The VAAC Darwin issued a warning on April 17, 2025, about “a volcanic ash plume that rose up to estimated 7000 ft (2100 m) altitude or flight level 070 and is moving at 10 kts in SE direction.”
Lewotobi,located on Flores Island,is also experiencing ongoing explosive activity. VAAC Darwin reported “a volcanic ash plume that rose up to estimated 9000 ft (2700 m) altitude or flight level 090 and is moving at 15 kts in SE direction.”
mount Semeru in East Java also saw volcanic activity.VAAC Darwin issued a report of “DISCRETE VA ERUPTION REP AT 17/1425Z MOV SW,” indicating a separate eruption with ash moving southwest.
Dukono, also on Halmahera, continues its explosive pattern. The VAAC Darwin warned of “a volcanic ash plume that rose up to estimated 10000 ft (3000 m) altitude or flight level 100 .”
New Zealand: White Island Alert Level Raised
Whakaari/White Island in New Zealand is showing signs of increasing unrest. “Despite limited direct observations in recent weeks, webcam images from Whakatāne and Te Kaha continue to show a rise in ash content within a steam and gas plume,” officials reported. “Similarly, the MetService has detected small amounts of ash in the plume using satellite imagery. From the coast, this appears as a hazy trail extending downwind from the volcano. these signs point to a gradual increase in eruptive activity,prompting the Volcanic Alert Level to be raised to Level 3.”
Observation flights confirm the increase in ash emissions. “Recent observation and gas measurement flights, along with satellite data, confirm this gradual rise in ash emissions,” authorities stated. “Although the emissions remain minor, northerly winds can carry the gas and ash plume toward the coast, where residents may notice sulphur-like odours. At this time, ash fall is not expected to impact the Bay of Plenty coastline.”
Further observations revealed more explosive events. “Observation flights have also revealed impact craters on the floor of the main crater, indicating that more explosive activity has occurred at times, with rocks being ejected several hundred metres from the vent. These types of explosive events are typical at whakaari, frequently enough resulting from growing vents becoming temporarily blocked or experiencing increased gas pressure.”
The rising volcanic activity is supported by monitoring data,as “Monitoring data,including gas flight results,thermal infrared temperature readings,and sulfur dioxide (SO₂) levels observed via satellite,all show slight upward trends. These are consistent with increasing volcanic activity and more frequent ash emissions.”
Central and South America: ash Advisories Issued
Several volcanoes in Central and South America are also under close watch.Santiaguito in Guatemala is experiencing ongoing explosive activity. The VAAC Washington warned about “a volcanic ash plume that rose up to estimated 14000 ft (4300 m) altitude or flight level 140 .”
Poas in Costa Rica prompted a warning from VAAC Washington: “VA EM DTCTD,” indicating detected volcanic ash emissions.
Nevado del Ruiz in Colombia was also monitored, although VAAC Washington reported “VA NOT OBS,” suggesting no ash was observed at the time of the report.
Sangay in ecuador triggered a “PSBL VA EM” advisory from VAAC Washington, indicating possible volcanic ash emissions.
Reventador, also in Ecuador, continues its explosive activity. VAAC Washington warned of “PSBL VA EMS to 14000 ft (4300 m),” signaling potential ash emissions up to that altitude.
Impact on Air Travel and U.S.Preparedness
These volcanic events,while geographically diverse,share a common threat: volcanic ash. The plumes can drift thousands of miles, posing a significant hazard to aviation. The U.S. Federal Aviation Administration (FAA) works in close coordination with VAACs around the world to monitor ash clouds and reroute air traffic as necessary.
The 1989 eruption of Alaska’s Mount Redoubt serves as a stark reminder of the dangers of volcanic ash.A KLM Boeing 747 encountered an ash cloud, causing all four engines to fail.The pilots managed to restart the engines and land safely, but the incident caused millions of dollars in damage and prompted significant changes in aviation safety protocols.
While the immediate impact of these eruptions is often felt most acutely by international air travel and communities near the volcanoes, the U.S. is not immune. The USGS Volcano Hazards Program actively monitors volcanoes within the U.S. and its territories, providing early warnings and risk assessments.
| Volcano | State | Alert Level | Most Recent Eruption |
|---|---|---|---|
| Kīlauea | Hawaii | Advisory | 2023 |
| Mount St. Helens | Washington | Normal | 2008 |
| Mount Redoubt | Alaska | Normal | 2009 |
Some may argue that the economic impact of rerouting flights due to volcanic ash is too high and that we should develop technologies to allow planes to fly through ash clouds. However, current scientific consensus and FAA regulations prioritize safety. The risk of catastrophic engine failure far outweighs the financial costs of temporary flight diversions.
FAQ: Volcanic Ash and Air Travel
- Why is volcanic ash perilous to airplanes?
- Volcanic ash contains abrasive particles that can melt inside jet engines, causing them to stall or fail. The ash can also damage the fuselage and obscure visibility.
- How do airlines avoid volcanic ash clouds?
- Airlines rely on VAACs and air traffic control to provide information about ash cloud locations. They then reroute flights to avoid the affected areas.
- What happens if a plane encounters volcanic ash?
- Pilots are trained to take immediate action, including turning away from the ash cloud, increasing engine power, and activating anti-ice systems. After landing, the aircraft undergoes a thorough inspection and maintenance.
- Are there any technologies being developed to detect volcanic ash in real-time?
- Yes, various research groups and companies

Interview: Aviation Expert on Global Volcanic Ash Crisis
Archyde News speaks with Dr. Aris Thorne, a leading volcanologist, on the recent surge in worldwide volcanic activity and its impact on air travel.
Introduction: The Volcanic Threat
Archyde News: Dr. Thorne, thank you for joining us. The headlines are dominated by reports of increased volcanic activity across the globe.From Indonesia to New Zealand and beyond, multiple eruptions are impacting aviation. Could you give our readers a general overview of the current situation?
Dr. Thorne: Thank you for having me. Indeed, we’re seeing a notable uptick in volcanic unrest and eruptions, notably in areas known for their active volcanism. The primary concern, as your reporting highlights, is the potential for widespread disruption to air travel due to the presence of volcanic ash plumes.
Impact on Air Travel and Safety Protocols
Archyde News: The article mentions the serious danger volcanic ash poses to aircraft. Could you elaborate on why ash is so hazardous, and what protocols are in place to mitigate these risks?
Dr. thorne: Volcanic ash is fundamentally dangerous as it’s composed of tiny, abrasive particles of rock and glass. These particles can enter jet engines, melt inside, and cause engine failure. moreover, it can damage the aircraft’s exterior, reduce visibility, and cause electrical problems. Aviation authorities, such as the FAA, work very closely with Volcanic Ash Advisory Centers (VAACs) to monitor ash clouds and reroute or ground flights when necessary. Pilot training is also essential, and they are trained to react in the unlikely event that an aircraft encounters an ash plume.
Specific Regions and Current Concerns
Archyde News: The news article details several volcanoes currently erupting. What’s the significance of the activity in Indonesia and New Zealand, given their locations and air traffic patterns?
Dr. Thorne: Indonesia, with its high concentration of active volcanoes, is a constant focus. Eruptions in areas with high air traffic volume, like those in Indonesia, pose notable challenges for airlines. The same can be said for the situation at Whakaari/White Island. The alert level has been raised, meaning we need to be extra vigilant in the area to monitor for ongoing activity in New Zealand as a growing tourist destination. The ash content from the eruptions further south could impact international flights within the region. Monitoring is especially significant.
Technological advancements and Future preparedness
Archyde News: while the FAA relies on rerouting current flights, are there any prospects for future technologies that might enable aircraft to fly more safely through ash clouds?
Dr. Thorne: The aviation industry is certainly always striving to improve safety and mitigate risks. Research is ongoing into real-time ash detection sensors that could provide more accurate and timely data to pilots while still prioritizing safety as standard protocol. however, it is imperative to note that the current consensus strongly favours safety over any potential risks. Prioritizing the risk of possible engine failure and other potential hazards greatly outweighs the current financial cost of rerouting flights. Ultimately,the most effective strategy remains proactively avoiding ash clouds whenever possible.
Conclusion: A Proactive Approach
Archyde News: Dr. Thorne, one final question for our readers. Given the rise in activity worldwide, is there anything people can do to ensure informed decisions when travelling?
Dr. Thorne: Absolutely. Passengers should stay informed. They should check for flight updates and alerts from their airlines prior to departure. Knowing about potential disruptions and being prepared for delays, or possible cancellations, is crucial. Moreover, people can stay up-to-date with news from trusted sources like Archyde News and follow the guidance of aviation authorities. The more informed we are, the better we can manage any potential travel disruptions.
Archyde News: Dr. Aris Thorne, thank you very much for your expert analysis.
