Turrialba Volcano has been steaming — literally — after the attention Arenal Volcano got for releasing smoke-like vapor in recent days. The Volcanological and Seismological Observatory of Costa Rica (OVSICORI) reported Wednesday that the same phenomenon that attracted attention to Arenal, which has been largely quiet for several years now, was at work in the crater of Turrialba Volcano.
The same effect was observed at Arenal Volcano recently. Arenal is still considered active but has fallen into what scientists expect to be a long slumber. For five years, since its dramatic eruptions stopped in 2010, OVSICORI has not registered any magmatic gasses or internal seismic activity at Arenal.
