Next Iceland eruption may happen at Eldvörp craters, be larger than Fagradalsfjall

• Inflation moving westward along Reykjanes peninsula based on satellite images

• Professor expects next eruption to happen at Eldvörp craters

• Eruption at Eldvörp could be longer and show different behavior than Fagradalsfjall

• Seismic activity at Fagradalsfjall is just tension between tectonic plates

• Fagradalsfjall unlikely to erupt again, while Eldvörp and Reykjanes ridge more likely
