The activity at the volcano has been intensifying since 14 February as an increasing trend is also shown in the rise of seismic amplitude detected by the local volcano observatory.
Strombolian activity has continued to pick up both in numbers and intensity. Frequent weak-to-moderate explosions occurred from the summit vent, but from time to time produced intermittent, relatively strong explosions. An elevated frequency of eruptions has been detected at the volcano at intervals of 8 to 14 per hour which is more than usual values.
Ash emissions reached up to 14,700 ft-15,700 ft (4,500 m-4,800 m) altitude and extended about 30 km to the south-southwest of the volcano.
The lava flow on the south-southwest flanks has increased in length, currently about 200 m long. Collapsing parts of the flow front generated constant incandescent avalanches towards the Ceniza and Trinidad ravines.
