Hundreds of people have been evacuated from their homes in southern Iceland, after the second volcanic eruption there in less than a month.
However, this volcano is actually under a glacier – which has partially melted.
There were fears that could set off floods from a nearby river, which had already risen by almost a metre.
This latest eruption is several kilometres further west from the volcano that erupted last month and also led to evacuations.
It quietened down earlier this week.
Iceland sits on a large volcanic hot spot in the Atlantic’s mid-ocean ridge.
The concern is that activity may begin at the nearby and much larger Katla volcano, located underneath the vast Myrdalsjokull ice cap.
Seismologists say this eruption does not appear to be a major one.
