The nation’s emergency commission is suggesting that residents around the Volcán Rincón de la Vieja maintain surveillance of the mountain and use radios to keep track of any eruptions.
The agency, the Comisión Nacional de Prevención de Riesgos y Atención de Emergencias, also said that those in charge of the national park that surrounds the volcano should continue to restrict access to tourists and others.
The mountain awoke in August and has thrown materials outside the crater. Some of the material entered the local waterways and caused the death of fish. That was Sept. 16.
Experts from the Observatorio Vulcanológico y Sismológico of the Universidad Nacional and the Red Sismológica Nacional of the Universidad de Costa Rica have both visited the site. They met with emergency commission personnel this week to discuss the volcano.
The experts have said they are not sure if the mountain will go back to sleep or continue with its eruptions and discharge of material. Experts at the Observatorio Vulcanológico have said that the volcano may have been awakened by the shock of an earthquake just 10 kilometers (6 miles) away in July.
