Volcano experts took a trip Friday to the edge of the Volcán Turrialba crater to get a good look at the vent that has been emitting gas and ash. The team was from the Red Sismológica Nacional.
Meanwhile, other experts went down into the crater of the Volcan Poás to take measurements of the water in the lagoon there. The temperature is an indication of what is going on below.
Póas has been erupting occasionally over the past six months, but the product of the eruptions have stayed in the crater.
Turrialba, on the other hand, seems primed for a major eruption. There has been limited activity for the last week, although gas and other vapor continue to be emitted by the principal vent.
