After years of calm, the Taftan volcano in southeastern Iran shows signs of activity. For the first time, its summit is swelling, signaling an increase in magma and gas pressure beneath the surface.
Taftan stands at 3,940 meters (about 12,927 feet) and is part of the Makran volcanic arc, formed by the Arabian Plate sliding under the Eurasian Plate. Although Taftan has had minor activity, like smoke emissions in 1902 and unverified lava flows in 1993, it hasn’t erupted in recorded history. Scientists believe its last major eruption happened around 700,000 years ago, long before humans existed.
Recently, a study revealed that Taftan’s summit rose by approximately 9 centimeters (3.5 inches) between July 2023 and May 2024. This swelling is unusual because it seems spontaneous—there’s no clear cause, unlike other volcanic eruptions that can be triggered by earthquakes or heavy rainfall.
The researchers speculate that hot water and steam deep underground could be pushing magma toward the surface. They noted changes in gas movement within the volcano’s structure might also contribute to the pressure increase. This means Taftan is not the dormant giant many believed it to be.
Volcanologists warn that while an explosive eruption isn’t imminent, increased activity may require closer monitoring. The researchers stress the importance of updating geological hazard maps and improving volcano monitoring systems to better prepare for potential risks.
This study adds a new layer of urgency to understanding Taftan’s behavior, suggesting that it may be more active than previously thought. As scientists continue to analyze the situation, the potential for change—whether gradual or sudden—remains a reality that cannot be ignored.
