Here is what they now generally expect from an event the scale of those that struck long valley and yellowstone : instead of a slow leak of red - hot lava as is seen creeping down the sides of kilauea volcano in hawaii , these eruptions feature supersonic blasts of superheated , foamlike gas and ash that rise buoyantly all the way into the earth ' s stratosphere , 50 kilometers high
对于造成长谷与黄石公园的那些爆发，或是相同等级的现象，目前他们普遍的看法是：这些爆发不像夏威夷奇劳亚火山缓慢渗出的红热岩浆、沿著火山侧蜿蜒流出；它们的特色是以超音速的冲击波，喷出极热、泡沫般的气体与火山灰，这些物质极易进入地球大气的平流层，上升到50公里的高处。
