The eruption was accompanied by loud rumblings that were heard from Mount Lokon and Mahawu observation post , located 5.5 km to the east of Mount Lokon. A column of ash eruption of 1500 meters, thick, gray–white color, was dispersed by a light wind to the north and northeast. The length of the eruption recorded on the seismograph had a duration of 575 seconds. Coordination with protection services is always carried out by the PVMBG regularly and it alerted to 20h00 (3-4 hours before the eruption). So far G. Lokon is still at the level of activity : ALERT (level III). People do not move within 2.5 km around the crater Tompaluan .
