After little more than 3 weeks of calm, the volcano has again produced a violent lava fountaining episode, known as paroxysm, from its SE crater this morning:
At 4.20 a.m. local time, volcanic tremor suddenly began to rise sharply. At 8.15 a.m., ash emissions were seen from the New SE crater, and strombolian explosions started a7 8.55 a.m., generating an ash plume that quickly rose to 4,500 m altitude.
This activity continued to increase, and by 9.55 a.m. resulted in lava fountaining that generated a tall column reaching approx. 9,000 m height and drifting to the ENE. At the time of this update, the activity is still going on, but seems to be reaching its end as tremor started to descend again.
As during the previous paroxysms, a lava flow is traveling from the southern rim of the crater towards the SW.
