A boulder estimated to weigh 2 tons fell on the pathway at the bottom of Almannagjá fissure in Þingvellir national park on Friday, when hundreds of tourists were in the park.
Ólafur Örn Haraldsson, chief park ranger at Þingvellir, told Vísir.is that such huge boulders had never broken from the walls of the rift before, except during the notorious earthquakes in South Iceland at the beginning of the century.
Considering what a popular tourist spot Almannagjá is, it was quite lucky that no one was harmed when the huge boulder fell on the foot path, but Ólafur estimates said that hundreds of people had walked along the fissure on Friday.
He has asked for experts to investigate what caused the boulder to fall and whether there’s danger of more falling rocks in Almannagjá.
