I've been following this elsewhere and am wondering if there will be any restrictions to aviation put in place. According to the latest VAA the ash plume is already at FL300 and will remain so for a while.
Volcanic Ash Advisory 5
The plume is moving West at approximately 25Kts which I appreciate is over the sea but not knowing the area particularly well I'm hoping someone with better knowledge of the vicinity might be in a better position to understand the implications for aviation if any.
