CATANIA, SICILY – March 4, 2026 – Mount Etna, Europe’s most active volcano, erupted on Wednesday, March 4, 2026, at approximately 1:12 PM local time. The explosive event at the Bocca Nuova crater sent an ash plume estimated to be 1.5 kilometers high into the atmosphere. The eruption occurred shortly after a magnitude 4.5 earthquake struck eastern Sicily, with its epicenter near Ragalna. While the volcanic event produced a short-lived ash emission, officials have stated there is no indication of a correlation between the earthquake and the eruption. This is a developing story.
The impulsive explosion at Etna’s Bocca Nuova crater was brief, lasting only a few minutes. High-altitude winds quickly dispersed the ash plume towards the northeast, resulting in a light dusting of ash on the volcano’s upper slopes. According to the Italian National Institute of Geophysics and Volcanology (INGV) – Etna Observatory, the event was characterized by a transient seismic amplitude spike, consistent with impulsive explosive activity at the summit crater. Infrasound monitoring also detected a signal associated with the explosion. Volcanic tremor amplitudes showed a moderate increase earlier in the day before stabilizing. No significant ground deformation was recorded by monitoring networks.
The magnitude 4.5 earthquake, which occurred at 7:05 AM local time on March 4, 2026, had a depth of 4 kilometers and its epicenter was located approximately 3 km northwest of Ragalna and 22 km southeast of Catania. The earthquake was felt across more than 20 municipalities in eastern Sicily. As a precautionary measure, schools in several towns, including Adrano, Biancavilla, and Catania, were temporarily closed. Local authorities reported numerous roof damages and collapses in dry-stone walls and ruins in affected areas. The INGV stated that there are no elements to suggest a link between this seismic event and the volcanic explosion later that day.
Mount Etna has a history of frequent eruptions, with its activity often characterized by lava flows and ash emissions. The last confirmed eruption began in 2022 and continues as of March 2026, with the volcano exhibiting near-continuous activity since 1900. The Bocca Nuova crater itself has experienced similar sudden, short-lived explosive events in the past, such as one on August 25, 2010. These phreatic events, often caused by sudden gas release, are a typical feature of Etna’s summit activity.
Emergency services are monitoring the situation closely. While the ashfall was light and confined to the upper slopes, authorities are prepared to issue advisories if conditions change. The Civil Protection of the Sicily region is coordinating response efforts and assessing any damage caused by the earthquake. Social media channels are abuzz with images and videos of the ash plume, with many users sharing their experiences of the tremors felt across the region. Verification of social media content is ongoing by news agencies.
Governments and international bodies have yet to issue formal statements, but volcanic observatories are maintaining heightened surveillance. Experts from INGV emphasize that while this was an impulsive event, the ongoing activity of Mount Etna necessitates continuous monitoring. “These types of phenomena occur suddenly without any geophysical precursor signals and are among the various types of explosive events that can occur at Etna’s summit craters,” a spokesperson for INGV stated. The proximity of this event to the recent earthquake is a point of focus for seismologists and volcanologists.
Looking ahead, the INGV will continue its detailed monitoring of both seismic and volcanic activity around Mount Etna. Further information on the long-term implications of the ongoing eruptive phase and any potential for increased activity will be provided as it becomes available. The Civil Protection department will also continue its damage assessment from the earthquake. For emergencies related to the earthquake or volcanic activity, residents are advised to contact local emergency services.
This is a developing story. More updates will be provided as information becomes available.
