Iceland’s largest volcano on the verge of eruption | GBRI

Towards the end of October, Iceland’s largest volcano – the Bardarbunga volcano – was racked with a string of earthquakes. According to experts, the earthquakes are often a sign of pressure building up in the magma chamber of the volcano in preparation for an eruption.

The Bardarbunga volcano is 6,590 feet tall and lies hidden beneath the Vatnajökull glacier, making it difficult to monitor directly beyond a few acoustic measurements. The recent earthquakes coming from the volcano are a result of magma moving through cracks and magma chambers. As the magma moves, it exerts pressure on the overlying and nearby rock and often causes earthquakes of various magnitudes.

However, the eruption does not appear imminent but could occur sometime in the next few years. After all, this is one of Iceland’s most active volcanoes and it’s only a matter of time until it erupts again.
