Preventive alert declared for three Costa Rican volcanoes

May 30, 2012

The National Emergency Commission (CNE) on Wednesday declared a preventive “green alert” due to recent seismic activity at three volcanoes: Rincón de la Vieja, in the northwestern province of Guanacaste, Poás, northwest of San José in the province of Alajuela, and Turrialba, in the eastern province of Cartago.

“The CNE’s alert is supported by reports from technical and scientific agencies that note the volcanoes are in constant activity,” the commission stated.

Turrialba Volcano, 70 kilometers east of the capital, has seen significant volcanic and seismic activity in recent months, prompting the National Seismological Network to upgraded its own color threat level to yellow.

Emissions of gas at Poás Volcano are expected to increase, and Rincón de la Vieja Volcano has also seen significant volcanic activity, the CNE noted.

Despite the warning, access to the volcanoes will remain open to the public, but visitors must follow guidelines issued at each national park’s entrance.
