A level of uncertainty has been declared at Sólheimajökull glacier in South Iceland. The glacier’s edge has risen 1.5 meters (4 feet, 11 inches) in recent days.
It is considered possible that a large piece of the glacier’s edge may break off causing a tidal wave in the underlying lagoon, visir.is reports.
The car park at Sólheimajökull is closed and people are urged to keep away from the immediate vicinity.
Guide Barði Theodórsson told ruv.is that he heard rumbling when he was up on the glacier with a group yesterday.
Icelandic search and rescue arrived in the area this morning and will continue to patrol the area into this evening.
Earth scientists and glaciologists are also expected to arrive in the area later today to measure developments and discuss whether the level of danger needs to be heightened.
