Two large steam and gas emissions were spotted Tuesday morning atop the Turrialba Volcano in the province of Cartago, east of San José, authorities from the National Seismological Network (RSN) at the University of Costa Rica said.
Turrialba residents said the two gas columns measure nearly 1 km in height and are moving towards the north face of the volcano.
"These gases are mostly water vapor, 90 percent, and the rest are volcanic gases," Raúl Mora Amador, the RSN's lead volcanologist explained.
One of the gas trails comes from the main crater, and the other rises from the east wall of the volcano, he added.
RSN geologists this Wednesday will conduct a flyover sponsored by the National Emergency Commission to perform regular measurements of temperature and observe changes at the top. On Thursday, RSN experts will visit the zone.
Access to the Turrialba Volcano National Park has been closed to visitors since last January, when spewing gas and ash alarmed locals and tourists.

Guatemalan Volcanoes Increase Activity
Guatemalan volcanoes Santiaguito and Fuego increased their activity in the last hours and the authorities recommended on Monday took all the necessary precautions with the surrounding air traffic.
The dispersion of ash in various directions and changes in wind pattern led to the National Institute of Seismology, Volcanology, Meteorology and Hydrology (Insivumeh) to warn about the civil aviation.
An Insivumeh report that Santiaguito volcano recorded 33 explosions in 24 hours, with a range of up to 800 meters above the crater, leaving ashes scattered in the southwest and southeast.
Santiaguito volcano is located in Quetzaltenango district, and its height is 2,550 meters above sea level.
The Insivumeh reported white and blue plume up to 100 meters above the crater, with displacement to the southwest, in the case of Fuego volcano, whose height is 3,763 meters above sea level and is located between the departments of Sacatepequez, Chimaltenango and Escuintla (center south).
