Prospective travelers to Costa Rica may note that three volcanoes in the Central American nation on Wednesday were placed on preventive "green alert" because of recent seismic activity.
They are Rincon de la Vieja in Guanacaste; Poas in Alajuela, and Turrialba in Cartago.
A green alert does not imply impending danger for tourists or nearby residents. In fact, the Tico Times is reporting that all three volcanoes remain open to the public, but with possible restrictions.
The National Emergency Commission (CNE) stated that the alerts were "supported by reports from technical and scientific agencies that note the volcanoes are in constant activity."
Turrialba, about 35 miles east of the capital city of San Jose, is under a higher "yellow" threat level, according to the National Seismic Network. Yellow signifies elevated unrest above a known background level of activity.
Orange signifies heightened elevated unrest and red signifies imminent eruption.
There's no such concern at present, of course, but the increase in seismic activity has piqued the interest of scientists.
