Alaska Volcano Eruption
I see that former eruptions resulted in an ash plume up to 15,000 metres.

Is this one causing any traffic disruption?
Alaska volcano Pavlof erupts causing flight diversions due to ash cloud
Mount Pavlof started erupting Sunday afternoon with little warning

■Ash from Calbuco volcano eruption cancels flights, raises health concerns
A volcano on the Alaska Peninsula erupted with little advanced warning over the weekend, spewing an ash cloud up to 6,000 metres high that prompted aviation warnings across the region.
Mount Pavlof, one of the most active volcanoes on the peninsula, began erupting shortly after 5 p.m. PT on Sunday, said Jessica Larsen, co-ordinating scientist with the University of Alaska Geophysical Institute.
"Pavlof is known to us for having a pretty quick onset to eruptions, it doesn't always give us long precursory signals," Larsen said.

Volcanic ash: Hazardous to planes, environment
"If you look at some of the seismic data that we have, the intensity really ramped up pretty fast. It was quite abrupt."
Photos on the Alaska Volcano Observatory website showed the plume towering over the icy slopes of Mount Pavlof and drifting to the northwest.

Red aviation alert
The Federal Aviation Administration issued a "red" aviation alert in response to the ash cloud, which required flights to be re-routed.
The alert could affect local and regional air traffic, as well as polar routes and cargo flights from Anchorage.
Larsen said the eruption did not pose any immediate danger to nearby communities on the peninsula, which were monitoring the ash fall.
The closest residential area is Cold Bay, located 60 kilometres southwest of Pavlof.
There have been more than 40 eruptions from Pavlof, including a series between May and November of 2014, which also triggered aviation warnings because of ash. Such events can last weeks or months.
The highest recorded plume from the volcano was nearly 15,000 metres
