Yesterday evening’s flooding ended just before 22.00; but earth scientists are warning that water is already collecting again.
Earth scientist Magnus Tumi Gudmundsson likens the situation to a bucket on a swivelling axle which tips over and empties when the water fills to a certain level. Further flash floods will follow if that happens. The volcano has a caldera which fills with melt water and then empties when full. Yesterday evening’s flood was bigger than the ones before it, although it was over sooner.
Gudmundsson says more floods can be expected in the coming days.
