At 14:45 local time this Tuesday, October 3rd, the Rincón de la Vieja Volcano in Guanacaste, Costa Rica registered an eruption that reached over 1,500 meters above the top of the crater, 3,416 meters above sea level (11,204.48 ft), the eruption was still going strong at 4 p.m. and is considered, according to Geologist Waldo Taylor Castillo from the National Seismology Network the biggest phreatic eruption this volcano has had since 2011.

The column of gas and materials is easily visible from different areas in Guanacaste and Alajuela, and due to the lack of wind in the area there was mild dispersion of the same to the west.

According to the Costa Rica National Emergency Committee, the area to the north of the volcano, where some rivers are born could be affected by lahars, ( mudflow or debris flow composed of a slurry of pyroclastic material, rocky debris and water), and due to this they recommend that communities near the rivers Penjamo, Azul and Azufrada stay alert.

Last Friday, September 29th, the Rincón de la Vieja volcano had another significant eruption with a column that reached more than 1,000 meters over the crater, and since then has maintained high activity, with a lot of fluid movement and high hydrothermal activity that has resulted in daily small size eruptions.
