The volcanic eruption in Holuhraun lasted almost six months, from August 31 (a minor eruption began in a similar location on August 29 and lasted a few hours) and ended on February 27, or 181 days in total.

The lava is approximately 40 meters (131 feet) thick at the lava field’s highest points, which is more than half the size of the Hallgrímskirkja church spire. The crater is taller than the church. The average thickness of the lava is ten to 14 meters, ruv.is reports.

The lava field measures 85 square km (33 square miles) and 1.4 cubic km (4,900 cubic feet). The Bárðarbunga caldera, which has been subsiding, measures 1.7 to 1.8 cubic km.

The lava which erupted in Holuhraun originated in Bárðarbunga volcano, which lies under Vatnajökull glacier.

About 1,000 people, scientists, public safety personnel, police officers and others, have been involved in eruption-related projects, including taking samples and guarding the closed-off area.
