Poas Volcano on Red Alert!

Many of my U.S. friends who have visited here have included a visit to Poas Volcano NP, which is (“as the crow flies”) just 53.5 km or 33.2 miles from me, though a 2 hour drive through the mountains. 🙂 It has been erupting daily now for a few weeks and increasing in intensity. Today …

The Costa Rican National Emergency Commission (CNE) has declared a red alert for Poás Volcano National Park due to increased volcanic activity, with ash plumes reaching up to 4,500 meters. The park is currently closed indefinitely, and authorities recommend that visitors stay away from the area. Adjacent areas, including Grecia, Sarchí, Alajuela, Poás, Naranjo, Río Cuarto, and Zarcero, are under orange or yellow alerts due to ashfall and gas exposure.

It has always been my favorite volcano to visit in Costa Rica, not only because the closest, but the only one you could look down in the crater and see the bubbling stuff, plus it has a second, older crater with a beautiful turquoise-colored lake. who knows what it will be like after these major eruptions?

Because I live south of Poas and most of our winds are East-West, I don’t get a lot of the ash fall, but some. Before breakfast on my terrace each morning, I wipe the glass-top table off with a Lysol Wipe and then a paper towel. They are black from the small amount of ash we do get. 🙂 Yet farmers near active volcanoes say the ash is excellent for growing vegetables! 🙂

Poas Volcano Erupting

Official photo

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.

Sweeping Out Yesterdays Volcano Dust

When my morning sweep includes gray dust, I know it erupted! Yesterday!
It is 104 km away or about 65 miles. Wind blows the ash across the valley.
No big deal! A broom does wonders! (Or vacuum for some.)

THE GOOD NEWS: Erupting Volcanoes may help slow global warming. Interesting!
