火山通告是指对飞行有重要意义或估计有重要影响的火山活动发生变化时,由航行情报部门发布的火山活动状态的通告。它的特殊性,使得我们在日常接收处理航行通告时很少收到此类通告,我国也不是一个火山活动频繁的地区,因此基本没有拍发过火山通告。 Volcano notification is a notification of the status of volcanic activity issued by the Navigational Intelligence Department in the event of a change in volcanic activity of significant or estimated significance to the flight. Its particularity makes it very rare for us to receive such notifications when we receive and process sailing notifications daily. Our country is also not a frequent area of ​​volcanic activity. Therefore, basically no volcano notifications were made.
