As Many As 132 Times of Karangetang Terekam Pos PGA

JAKARTA - The Mount Karangetang Fire Observation Post (PGA) recorded as many as 132 times of the Karangetang Mountain eruption, on Siau Island, Sitaro Islands Regency, North Sulawesi in the period of Friday (26/12).

"The observed crater smoke is white with a thick intensity and a height of 5-10 meters above the crater peak. At night, the fire appeared to be about 5-10 meters," said the report's author, Umar Syarif, which was shared in the 'Sitaro Volcano Info' chat group, in Manado, Saturday.

In addition to the thrust earthquake, it was also recorded that there were seven non-harmonic tremor earthquakes with an amplitude of 5-30 millimeters, duration: 28-85 seconds, and three harmonic tremor earthquakes with an amplitude of 6-34 millimeters, duration 38-61 seconds.

A hybrid/multiple phase earthquake was also recorded, with an amplitude of 7 millimeters S-P: 0 seconds, duration 23 seconds, two shallow volcanic earthquakes with an amplitude of 7-10 millimeters, duration 7-8 seconds.

The PGA post also recorded two deep volcanic earthquakes with amplitudes of 14-50 millimeters, S-P: 0.8-1 second for 9 seconds, and one distant tectonic earthquake, amplitude 10 millimeters, S-P: 14 seconds for 30 seconds.

The current activity level of Mount Karangetang is Level II (Alert).

The Geological Agency is expected to comply with recommendations such as people and visitors/tourists not approaching, not climbing and not doing activities within the predicted danger zone, namely a radius of 1.5 kilometers from the peak of the two craters (northern crater) and the main crater (south) and the sectoral expansion area to the southwest and south as far as 2.5 kilometers.

It is also hoped that they will be aware of lava discharge and hot cloud discharge that can occur at any time from the previous accumulation of lava material because the condition is not stable and prone to collapse, especially in the south, southeast, west and southwest sectors.

The next recommendation is for people living around the banks of rivers that flow from the peak of Mount Karangetang to increase their readiness from the potential threat of rain lahar and flash floods that can flow to the coast.
