Active Volcanoes Erupting Now: Shiveluch, Mayon & More – March 15, 2026 Update

Volcanic Unrest Intensifies Globally: Updates on Shiveluch, Mayon and Multiple Other Eruptions

A surge in volcanic activity is being observed across the globe, with significant eruptions reported in Russia’s Kamchatka Peninsula, the Philippines, Indonesia, and several locations in South America and the Pacific. As of March 15, 2026, heightened alerts are in effect for multiple volcanoes, disrupting air travel and prompting local evacuations. The most prominent event is a major explosion at Shiveluch volcano in Kamchatka, sending an ash plume reaching approximately 8,000 meters (26,000 feet) into the atmosphere. This event, alongside ongoing activity at volcanoes like Mayon in the Philippines and Semeru in Indonesia, underscores the dynamic and often unpredictable nature of volcanic hazards worldwide.

Shiveluch’s Powerful Eruption and Regional Impact

The eruption at Shiveluch volcano, located in Russia’s Kamchatka Peninsula, is currently the most significant event. A major explosion on March 13th produced a substantial ash plume that drifted northeast towards the Bering Sea. Volcan Discovery reports that the plume reached an altitude of 8,000 meters. Eyewitnesses in the nearby village of Klyuchi reported hearing explosions. The volcano, estimated to be between 60,000 and 70,000 years old, consists of Old Shiveluch, an ancient caldera, and the active Young Shiveluch. The ash cloud poses a hazard to aviation, prompting an orange aviation alert for the surrounding area. Caliber.az notes the volcano lies approximately 50 kilometers from Klyuchi and 450 kilometers from Petropavlovsk-Kamchatsky.

Shiveluch is part of the Kuril-Kamchatka volcanic arc, formed by the subduction of the Pacific Plate under the Okhotsk Plate. This process creates magma that rises to the surface, resulting in volcanic activity. Wikipedia details this geological process, explaining how the melting of minerals due to water and other materials contributes to magma formation.

Philippines: Mayon and Canlaon Display Volcanic Activity

In the Philippines, both Mayon and Canlaon volcanoes are exhibiting signs of unrest. Mayon volcano experienced an eruption on March 15, 2026, with the Volcanic Ash Advisory Center Tokyo (VAAC) issuing a report detailing the event. Canlaon volcano also remains under observation, with the Volcanic Ash Advisory Center Darwin (VAAC) issuing advisories regarding its activity. These eruptions highlight the Philippines’ location within the Pacific Ring of Fire, a region known for frequent seismic and volcanic activity.

Indonesia: Ibu and Semeru Continue to Erupt

Indonesia, another country situated within the Pacific Ring of Fire, is currently experiencing eruptions from Ibu volcano on Halmahera Island and Semeru volcano in East Java. Ibu volcano has been emitting ash plumes, with the VAAC Darwin issuing reports on the plume’s altitude and direction. Semeru volcano continues to exhibit explosive activity, with a volcanic ash plume reaching an estimated 15,000 feet (4,600 meters) and moving southeast. The ongoing activity at Semeru has prompted concerns for nearby communities and potential disruptions to air travel.

Ecuador and Beyond: Reventador, Sangay, and Global Volcanic Updates

Further afield, Reventador and Sangay volcanoes in Ecuador are also experiencing ongoing eruptions, with ash plumes reaching significant altitudes. Volcanic Ash Advisory Center (VAAC) Washington has issued reports on both volcanoes, detailing the height and movement of the ash plumes. Additional volcanic activity has been reported in Vanuatu (Aoba), Flores Island (Lewotobi), and other locations around the world, including Iceland (Theistareykjarbunga) and Tonga (Late). The widespread nature of these eruptions underscores the interconnectedness of global volcanic systems and the potential for far-reaching impacts.

Understanding Volcanic Ash Advisories and Aviation Safety

The Volcanic Ash Advisory Centers (VAACs) play a crucial role in monitoring volcanic activity and providing timely information to the aviation industry. These centers, operated by meteorological organizations around the world, analyze volcanic ash plumes and issue advisories to airlines and air traffic control. The advisories provide information on the location, altitude, and concentration of ash, allowing airlines to reroute flights and avoid areas where ash could damage aircraft engines. The color-coded alert system – green, yellow, orange, and red – indicates the level of risk to aviation. An orange alert, as issued for Shiveluch, signifies that the volcano is erupting and poses a potential hazard to aircraft.

What’s Confirmed and What Remains Unclear

Confirmed: Multiple volcanoes are currently erupting across the globe, including Shiveluch (Russia), Mayon and Canlaon (Philippines), Ibu and Semeru (Indonesia), Reventador and Sangay (Ecuador), and Aoba (Vanuatu). Ash plumes from these eruptions are posing a hazard to aviation and prompting local alerts. The geological processes driving these eruptions are well-understood, linked to plate tectonics and magma formation.

Unclear: The duration and intensity of these eruptions remain uncertain. Predicting volcanic eruptions is a complex science, and although scientists can monitor volcanic activity and identify potential hazards, accurately forecasting the timing and magnitude of eruptions is challenging. The long-term impacts of these eruptions on regional air quality, agriculture, and infrastructure are also yet to be fully assessed.

Looking Ahead: Monitoring and Preparedness

Continued monitoring of these and other active volcanoes is essential to mitigate the risks associated with volcanic eruptions. VAACs will continue to provide timely advisories to the aviation industry, and local authorities will remain vigilant in monitoring volcanic activity and preparing for potential evacuations. International collaboration and data sharing are crucial for improving our understanding of volcanic processes and enhancing our ability to forecast and respond to volcanic hazards. The current situation highlights the importance of investing in volcanic monitoring infrastructure and developing effective emergency preparedness plans to protect communities at risk.
