The Turrialba volcano erupted twice Monday morning, and the experts say there is enough movement under the mountain that more eruptions are expected.
The first eruption was at 7:22 a.m. The second, smaller one was at 8:26 a.m. The first plume of ash and gas went about 3,000 meters above the volcano peak, said the Observatorio Vulcanológico y Sismológico de Costa Rica. The second plume was just half that.
Almost at the same time, at 8:19 a.m., the Poás volcano produced a small eruption that broke through the surface of the crater lake. The emissions were contained within the crater.
The Turrialba volcano continues to produce vapor, as usual.
The ash from the eruptions went to the northwest, and may have affected some pilgrims on their walk to Cartago. There were a lot of pilgrims on the roadways Monday because the day was a holiday.
The Observatorio Vulcanológico y Sismológico said that there were two eruptions by Turrialba Sunday night that produced some rock as well as ash.
Flight operations were normal in Alajuela and Pavas, but American Airlines inexplicably halted a flight bound to Juan Santamaria airport from Charlotte, North Carolina. The aircraft was turned around when the crew heard about the eruptions, and passengers were spending a night at the airport.
