A scientist in New Zealand is helping to monitor the Fagradalsfjall volcano in Iceland with warnings the probability of an eruption remains high.
Authorities evacuated nearly four thousand people from the fishing town of Grindavik this week as magma coursed through the ground beneath.
Sigrun Hreinsdottir knows the volcano well - she's from Iceland and is currently working with GNS Science in Lower Hutt.
Hreinsdottir spoke to Charlie Dreaver.
