During May 2015, GGC recorded an increase in small seismic activity associated with fracturing of rock inside the volcano, compared to April. The quakes (all below magnitude 2) were concentrated in the northern and eastern sectors of the volcanic edifice at depths ranging between 3.4 and 6.6 km. No other significant changes were detected at the volcano and its alert status remains at "green".
A slight increase in rock-fracturing earthquakes has also been detected in the area south of Nevado de Santa Isabel volcano, in the area known as Cerro Spain.
