Is it an actual uptick, or an uptick in reporting? There are a lot of volcanos in the world and activity that a few years ago would be of only local concern now gets out on to the internet more often.
As someone who follows this, I’d call it an uptick, and bigly.
Flying out of St. Vincent was a problem because the plane took off downhill, down wind , and many days they would not take passengers flying out because the wind was too high and the plane couldn't gert much of a "Lift" going down hill with the wind blowing in that direction.
I was there prior to St. Vincent getting their Independence.
I expect the runway is more modernized now, that it has become a tourist attraction Island, complete with a cruise ship stop. -Tom
