Volcan Santiaguito in Eruption

Volcan Santiaguito, on the skirts of Volcan Santa Maria, near Quetzaltenango is in eruption.  The episode began with loud explosions accompanied by ash ejection to a height of 5 kilometers.  Lava is flowing from the vent.

The ash fall is dispersing towards the south, southwest and west.  Visibility in those areas is severely impacted.  Ash is being reported in the city of Retalhuleu, recently damaged by the November 7th earthquake.

Three earthquakes also occurred in the region at around midnight.
