Since erupting on June 12 the Sarychev volcano continues to wreak havoc for air travellers.

According to CBC Canada, Air Canada, Air China, Asiana Airlines and Korean Airlines all cancelled or delayed flights in and out of Vancouver International Airport on Tuesday. These are all routes that would pass near to the volcano.

The dust plume has now spread as far as 1500 miles from the site.

The NASA Earth Observatory has a nice series of pictures that for the moment is updated daily.
