The Volcanological and Seismological Observatory (OVSICORI) reported that an eruption was recorded in the Rincon de la Vieja Volcano in Guanacaste.
According to the report, the eruption occurred at 5 am on Wednesday and was about two minutes in length. “The expelled gas column reached a thousand meters in height from the crater, and at 2,916 meters above sea level."
According to the National Seismological Network, there have been 24 events of this type since June, with between three and nine are reported monthly at this volcano.
OVSICIRI reports that, "The seismic activity is greater, with respect to the one registered on Tuesday the 16th. The main eruption was mainly of steam, water, gas, aerosols and sediments (ash) .The top of the volcano was covered by a whitish layer of water and sediments ejected from the hyper-acid lake of Rincón, the eruption was observed by neighbors to the north of the volcano and by the webcam located in Sensoria Land of Senses."
The specialists remind the public that the park around the volcano is closed to the public. It is also recommended that people living in the vicinity of the pack "take precaution and avoid being in the vicinity of the rivers that descend the northern flank of the volcano, because of the potential danger of water slides in the lagoon."
According to institute statistics, "this volcano has maintained emissions of gas and steam since June 26. In addition, tremors have been recorded in the vicinity of the volcano."
The two largest eruptions were on October 2 and October 16 when there were swarms of earthquakes and eruptions of ash and strong gases.
Rincon de la Vieja is an active andesitic volcano complex in north-western Costa Rica, about 23 km from Liberia in the province of Guanacaste. Its name means "The Old Woman's Corner," a reference to a local legend about a girl whose lover was thrown into the crater by her father. She became a recluse living on the mountain, and was credited with powers of healing. Stands 1,916 meters (6,286 ft) above sea level.
In another case, the Turrialba Volcano in Cartago, has maintained its activity. "Since August 28, 2018 there has been a continuous eruption in the Turrialba volcano, with a column that rises to 500 meters above the height of the crater and 3840 meters above sea level.”

The expelled gas column reached a thousand meters in height from the crater, and at 2,916 meters above sea level.
Specialists confirm that the seismic activity is lower, compared to Tuesday. In addition, this event was of lesser magnitude than that recorded on October 5 , "the eruption is of lesser quantity than the previous days. There are moderate emissions of ash and ejection of fresh lava fragments from the strombolian eruption on October 5. Light continues to shine in the west crater indicating temperatures equal to or greater than 600 C. Turrialba continues to emit gases, aerosols and small amounts of ash persistently. "
As for the records of the volcanic activity, gas and steam emissions have been presented since June 12. The level of tremors in the vicinity of the volcano has been moderate and constant.
Turrialba Volcano is an active volcano in central Costa Rica that has been explosively eruptive in recent years including 2016 and in January, March and April 2017. Visitors used to be able to hike down to the main crater, but increased volcanic activity (2014-17), resulting in large clouds of volcanic ash, has caused the surrounding Turrialba Volcano National Park to close.
The stratovolcano is 3,340 m (10,958 ft.) high and is about 45 minutes from the Atlantic slope town of Turrialba. The summit has three craters, the largest of which has a diameter of 50 m (160 ft.). Below the summit is a mountain range and mountain forest, with ferns, bromeliads, lichens and mosses. Most of the forest is either primary or secondary forest.
On September 19, 2016, an eruption lasting around fifteen minutes was the first event of many through the day that eventually covered the metropolitan area with ash.
