The ash cloud posed a risk to jet planes because it rose to around 30,000ft which is the normal cruising altitude for passenger planes.

火山灰云为喷气式飞机造成了威胁，因为其升至约30000英尺是客机正常的巡航高度。

Volcanic ash can clog⁵ up and damage jet engines while the tiny particles of glass in the ash can also melt and block the ventilation holes which can cause the engines to overheat and stop working.
