Professor Links says scientists can use computers to quickly model where radioactive material has blown and settled. Then they measure how large an area is contaminated.
林克斯教授表示，科学家可以使用电脑快速模拟什么地方会受放射性物质影响，然后计算出受污染区域的大小。

As the aerosolized materialsettled back down to the surface and cooled, it formed glass beads.
火山将超高温的熔岩喷发至空中，雾化的物质随即凝固，并落回地面冷却，由此形成了各种玻璃珠子。

Candy Hansen from Nasa added: 'the colour of the ice surrounding adjacent streaks of material suggests that dust has settled on the ice at the bottom after similar events.'
