Moderate eruptions of Rincón de la Vieja volcano continue |

Seismic activity and steam eruptions are continuing at the Rincón de la Vieja Volcano* in Liberia in the province of Guanacaste. They began, says the Volcanological and Seismological Observatory staff on Friday, March 29. The observatory reports that on Monday beginning at 8 a.m. they recorded a two minute eruption that sent a column to 600 meters above the crater and 2,516 meters above sea level, "The volcano continues to emit low concentrations of magmatic gases. We also registered volcanic earthquakes on low frequency." Beginning Friday, March 29th, at 8:43 p.m. intermittent low-frequency earthquakes were reported. They continued until Monday. No ashfall or sulfur odors were recorded. As A.M. Costa Rica reported on Jan. 18th, an eruption of the Rincón de La Vieja Volcano caused the death of fish and caiman in the area. According to volcanologists, at 1:00 a.m. a two minute eruption was reported. Due to poor visibility and bad weather, the height of the gases that were expelled by the volcano could not be recorded. Half an hour later, a second eruption was generated that caused a flow of material on the edges of the volcano and the flow reached the rivers. This type of flow is called a lahar, a violent flow of pyroclastic material, rocky debris, and water. The material flows from a volcano, typically along a river valley. |
These eruptive events are phreatomagmatic, that is to say, explosions occur because of the magmatic gas interactions with the active crater’s acid lake, and occasionally, small amounts of magma rise and hit the lake, generating even more violent explosions. A witness reported that after the eruption and the sediment in the rivers, the people observed how the fish of the river began to float and that they even collected them in sacks. The dead fish collected had burned gills, and the yellow and burned scales. A dead caiman was found on the river bank. The Rincón de La Vieja Volcano has been in a stage of intense phreatic activity since 2011 with episodes of eruptions and increased activity since the end of 2015. Access to Rincón de la Vieja volcano is being regulated.
