Mount Fentale Volcano Emits Methane

Recently, scientists observed extraordinary methane emissions from Mount Fentale, a volcano in northern Ethiopia. This unusual volcanic activity has raised concerns about its potential impact on local ecosystems and global climate change. The event has attracted attention due to the sheer volume of methane released, which is a potent greenhouse gas.

The Methane Emission Phenomenon

Mount Fentale has been emitting methane at an alarming rate. Starting from 31 January, emissions peaked at 58 metric tonnes per hour. This is far greater than typical volcanic emissions, which usually consist of carbon dioxide and sulfur dioxide. Methane is known to be 28 times more effective at trapping heat than carbon dioxide over a century.

Historical Context of Mount Fentale

Mount Fentale is not known for frequent eruptions. Its last recorded eruption was in 1820, which resulted in lava flow. Historical records indicate earlier eruptions, including one in the 13th century that devastated an Abyssinian town. Recent signs of volcanic activity, such as magma intrusion, were noted as early as September 2024.

Decline of Emissions and Future Monitoring

By 9 February, methane emissions began to decline. The reasons for this decrease are not fully understood, suggesting it may have been a temporary geological event. Researchers continue to monitor the situation closely to determine if similar emissions could occur elsewhere.

Implications for Climate Change

The unprecedented methane emissions from Mount Fentale highlight the need for comprehensive tracking of greenhouse gases. Even short-term increases in atmospheric methane can contribute to climate change. This event emphasises the importance of understanding natural sources of methane in the context of global climate mitigation efforts.
