So though the total volume of the eruption, put at about 0.14 cubic kilometres, is low, the amount of ash capable of travelling long distances is high.
所以，尽管这次喷发的规模不大，大约0.14立方千米，但大量灰尘扩散到很远的地方。
The Oruanui eruption probably managed that, but a surer candidate is Sumatra's Toba blast, which released 2800 cubic kilometres of hot rock, ash and dust about 70,000 years ago.
奥努伊火山爆发就可能属于这一类，但是一个更有把握超级火山的候选者是苏门答腊岛的多巴火山爆炸。约在70 000年以前，多巴火山在爆发时释放了2800立方公里的灼热的岩石、火山灰和尘埃。
