For some of my visitors whom I took to see the closest volcano to Atenas, Poas, you might like to know that it is now erupting and no visitors allowed. It is still not giving us the dust that Turrialba still gives occasionally, but it is an hour+ drive away and is closed as a park and for 5 km around it.
Read more in this Tico Times Article and see rocks, etc. thrown around the area. We have had no visible effects in Atenas but best to keep our distance for now. A few people living on the northern slopes claim they could see the eruption from their houses.

Facts About Costa Rica Volcanoes, with some 200 vestiges of volcanoes, only 100 have any kind of activity and today only 2 or 3, Poas, Turrialba, and Arenal significantly, but others could.
