Ancient Dormant Volcano Shows Signs of Awakening

Researchers suggest that a long-dormant volcano might be gearing up for a significant volcanic event.

Evidence of Volcanic Activity Detected

Situated in eastern Iran near its border with Afghanistan, the Taftan volcano has shown signs of possible resurgence. Despite its lack of eruptions over the past 700,000 years, recent scientific studies have detected signs of activity.

Significantly, rapid surface uplift was observed near the 13,000-foot peak of Taftan between July 2023 and May 2024, indicating increased volcanic pressure beneath the surface.

Potential for an Explosive Eruption

The absence of external factors such as earthquakes or rainfall leading to this activity suggests that an internal buildup, possibly leading to an explosive eruption, is likely in the near future.

The increased pressure may be due to changes in the volcano's gas permeability and undetected movements of deep magma.

Historical Context and Current Observations

Despite frequent fumarole emissions, indicating minor volcanic activity, Taftan has not experienced a major eruption since it last did 700,000 years ago. Historical accounts of eruptions in 1902 and 1993 remain unconfirmed. The volcano's remote location contributes to limited monitoring capabilities.

Need for Enhanced Monitoring

The study underscores the urgent need to enhance the monitoring of the Makran subduction volcanic arc, covering a 275-mile stretch along the Indian Ocean. Improved surveillance could provide critical insights into volcanic hazards in the region.

"These observations highlight Taftan's latent potential for increased activity," the study authors noted, calling for an upgraded approach to volcanic risk assessment and surveillance in the area.
