Scientists monitoring it believe that a swelling magma reservoir six miles underground may be causing the recent uplifts.

监测它的科学家认为，造成近期上升的原因，很可能是地面以下六英里的岩浆库不断膨胀。 他们也一直在留意许多年前被挤压进火山的那团薄饼般的熔岩。

In order for earthquakes to set off a volcano, the magma reservoir beneath the fiery mountains must be already primed to blow.

为了使地震能引起火山爆发，在火热的山体地下的岩浆必须能够流动。

For instance, the study suggests that the magma-mixing process is driven by buoyancy-that a hot blob of magma rising into the reservoir can completely overturn the mush.

例如，研究认为混合过程受浮力驱使——上涌到岩浆库的炽热岩浆能彻底倾覆熔浆。
