I did not witness the beginning of the great eruption personally, because i was in denver at the time . 我没有亲眼得见大喷发的开始，因为当时我正在丹佛。
Many of the procedures we tried had never been used before on an active explosive volcano . 我们采用的许多试验方法，过去还从未在一次活喷发火山地区用过。
Scientists suspect that this slow rate explains why eruptions occur infrequently in the area . 科学家们认为，这样慢的速度可以解释为什么在这一地区火山喷发并不频繁。
Long-term recycling of these materials will occur when they are melted to form magmas erupted from the benioff zone . 当这些物质熔融形成岩浆，从贝尼奥夫带喷发时，这些物质将发生长期的再循环。
Also, we were able to experiment with scientific measurements that may help us better predict future volcanic eruptions . 同样，我们也可用某些科学的测量手段进行实验来帮助我们更好地预测未来的火山喷发。
Distinct layers of ejected material on the volcanoes' slopes are allowing geologists to construct the chronological sequence of their formation . 喷发出来的物质层次分明地留在火山斜坡上，使地质学家们可以确定它们形成的年代顺序。
