The National Emergency Commission announced that access to the Poás Volcano National Park* will remain closed today and until further notice.

According to the Commission, observations made by specialists on Monday showed that the seismic signal associated with the movement of fluids in the internal conduits of the volcano remains high.

"Given this activity and intending to protect the lives of both park officials and visitors, the Commission and the Volcanology Technical Advisory Committee recommend that the Poás Volcano National Park administration be closed on Tuesday," said the Commission in its statement. "The probability of the occurrence of eruptions remain high."

The Commission maintains constant communication with scientists, who are actively monitoring the Poás volcano.

According to the National Volcano Observatory, at 5:40 a.m. Monday an eruption with a duration of 5 minutes was recorded at Poás volcano, with a column that rose to 1,000 meters above the crater and 3,708 meters above sea level.

According to specialists, falling ash and the smell of sulfur were reported in the villages of Sarchí and Grecia."

Tuesday authorities are expected to inform the public when access to the volcano will reopen so people who bought tickets in advance can claim them.



Last week, as A.M. Costa Rica reported,
authorities reopen Poás Volcano access to visitors, after on Sept 22nd, a continuous steam column rose to 1,000 meters (3,200 feet) above the height of the crater and 3,708 meters (12,165 feet) above sea level.

Due to the steam eruption, the National Emergency Commission ordered the closure of the entrance to the volcano.

On September 19th, park rangers reported an increase in the intensity of acid rain.

According to volcanologists, the gases emanating from the volcano, mainly sulfuric acid, when combined with rain or cloudiness, produces rain that may cause skin irritation.

On June 18th, was registered an eruption that lasted approximately six minutes. However, the height reached by the gas column could not be calculated due to cloudy conditions at the site.

In their report, specialists registered an increase in seismic activity. "In the past week, several volcano-tectonic earthquakes of low amplitude and magnitude less than 2.0 have been registered. This is happening under the crater suggesting fracturing of rock under the Poás crater,” said the specialists.

People in the area reported to the National Emergency Commission that several loud noises were heard and then an erupting column ascending from the crater of Poás was seen, followed by ash fall in the towns of Cajón, San Luis, Los Ángeles, San Miguel, San Isidro, San Roque," said the Commission in its report.

In February, a series of eruptions were reported. And after 24 hours of observation, there was a decrease in seismicity and volcanic gases, carbon dioxide, and sulfur dioxide.

Volcano access was reopened in September 2018 after being closed for 16 months.

According to the Tourism Institute, the country has more than 200 volcanoes formations identified, dating back more than 65 million years. More than 100 of which show signs of active volcanic activity.
