Late night yesterday, a number of strombolian explosions occurred from the volcano.
The activity has been of a glowing hot, plastic lava spatter (scoria) involved thrown at an approx. height of 100 meters into the air and landing 400 meters off the crater in the SW direction. During ejecting, typical parabolic ballistic trajectories have been observed as they have been falling back to the edifice.
Prior to eruptions, the Servicio Geológico Minero Argentino’s (SEGEMAR) seismic network registered a magnitude M 2.4, associated with rock fracturing at depth and allowing magma rises further to the active lava pond within the crater. The seismic activity continues at slightly elevated levels at the time of this update.
Gas and water vapor emissions continued to release from the summit vent dissipating NW throughout the morning.
The Volcanic Alert Level remains at Yellow with 500 meters exclusion zone around the main crater in place.
