Potential Reawakening of Dormant Volcano After 700,000 Years

Research suggests that a long-dormant volcano might soon erupt explosively. Signs of volcanic activity have been detected in the Taftan volcano, located in eastern Iran, near the border with Afghanistan.

Although there has been no recorded eruption in the past 700,000 years, scientists have observed unsettling signals that indicate possible volcanic activity.

Monitoring the Taftan Volcano

From July 2023 to May 2024, significant ground uplift was recorded around Taftan's peak, standing approximately 13,000 feet tall. Analysis methods designed to mitigate atmospheric distortions determined that neither rain nor seismic activity caused this change.

This uplift suggests a strong likelihood of an impending volcanic eruption, as noted by the research team.

Gas Activity and Volcanic Movements

Alterations in gas passage within the shallow volcano regions, alongside possible unnoticed movements of magma deep below, have possibly increased pressure within the hydrothermal system.

Though Taftan often shows gas venting or fumarole activity, geological evidence shows it hasn't erupted substantially in hundreds of thousands of years.

Challenges in Monitoring Remote Volcanic Sites

The remote setting of Taftan means it lacks the intensive observation seen at other volcanic sites. Currently, satellite technology offers the primary means of observing shifts from dormancy to active states in isolated and poorly monitored volcanoes.

Regional Implications and Future Risks

This study emphasizes an urgent overhaul of the volcanic hazard assessments for the Makran subduction zone, extending some 275 miles along the Indian Ocean. Furthermore, establishing comprehensive networks for monitoring volcanic activity in this area is crucial.

The scientific report concludes by underscoring that Taftan volcano is experiencing more activity than previously identified, indicating that potential risks could be underestimated.
