Rincón de la Vieja volcano, Costa Rica: activity updates

Rincón de la Vieja volcano (Costa Rica): phreatic eruption on 18 June 2017

Friday Jun 23, 2017 17:14 PM | BY: T

OVSICORI-UNA reported that on 15 June a diffuse plume of mainly water vapor rose 50 m above Rincón de la Vieja's crater rim. A small hydrothermal explosion from the crater with the highly acidic lake was detected around noon on 18 June.
In a report posted the next day OVSICORI-UNA noted that seismicity was characterized by low-frequency events, volcano-tectonic events, and tremor with intensifying amplitude; the seismic patterns were similar to those that preceded the phreatomagmatic events on 23 May and 11 June, though the recent seismicity was not as energetic.

Last Wednesday's eruption at Rincón de la Vieja volcano (OVSICORI-UNA)
Saturday, Mar 12, 2016
The volcano had a new explosion from its crater lake last Wednesday 8 March. The eruption threw deposits of mud and ash onto the northern side of the crater to up to 120 m distance from the rim and generated a small plume of ash that caused light ash fall in nearby villages in up to 6 km distance to the north. ...

Sunday, Sep 21, 2014
The volcano increased its activity. Since 17 Sep, phreatic explosions have regularly occurred from the main crater which contains an acid lake. Although none was observed directly, at least 6 explosions could be identified by seismic signals. An aerial survey yesterday showed no fresh deposits, which suggests that the eruptions were rather small and did not eject material beyond the lake. ... [more]
