Based on visual observations of activity, the Mount Lokon was observed emitting thick white smoke diffuses up to a height of 25-250 m.
Seismicity of Lokon is dominated by continuous tremors, volcanic earthquakes, earthquake swarms (VB) and emission tremors. During the period from 30 December 2015 to 7 January 2016, seismicity has tended to fluctuate .The volcanic earthquakes shallow (VB) have increased significantly since January 3, 2016, recording a total of 37 episodes per day, which shows that the volcanic activity comes to the surface. The possibility of great volcanic eruption of energy is increasing. The increased incidence of seismicity in shallow areas is usually transmitted directly as an éruption. The amplitude of tremor shows a relatively constant value of 0.5 to 6 mm. The RSAM data showed an increase from January 3, 2016 which did not persist and even returned to fluctuating values ??of the beginning. During the period of 30 December 2015 to 7 January 2016 they have not shown a significant increase of energy.
The potential of eruption danger is still there, but it is impossible to predict when and with what intensity.
This danger of eruption of Mount Lokon currently take the form of emission of volcanic ash that will propagate depending on the wind direction and speed.
Based on visual observations, seismicity, SSAM values and potential threats of eruption of Mount Lokon dated from January 7, 2016 at 18:00, the level of volcanic activity of Lokon is at LEVEL III (Siaga).
Intensive monitoring is ongoing to evaluate the activity of Lokon. The socialization of the danger of eruption of Mount Lokon is intensively pursued so that people around the volcano can get the latest information of Lokon activity.
If there is a decrease / increase change in the volcanic activity of Mount Lokon significantly, the activity level can be lowered / raised in accordance with the level of activity.
