‘Witch’s hair’ glass splinters spread as Iceland volcano continues to erupt

So-called 'witch's hair' - thin, sharp, glass needles that are created in volcanic eruptions – have started falling on communities across the Reykjanes peninsula as a volcano in southwest Iceland continues to erupt.

"The colour of it was really amazing," Sam Wilkinson, a tourist from Australia, said.

"It felt like we were being drawn in by the fire."

This is the sixth time the volcano on the Reykjanes Peninsula has erupted since December.

Authorities say the eruption's effects remain localized with road closures but do not
