Mount Agung when removing smoke as high as 1500 meters, Saturday (7/10/2017) from the Observation Post of Gunungapi Agung, Rendang Village, Karangasem.

AMLAPURA – Center for Volcanology and Geological Hazard Mitigation (PVMBG) Geological Agency Ministry of Energy and Mineral Resources since three days ago has been measuring the sulfur content (SO2) of Mount Agung. The result until yesterday has not detected sulfur levels in a radius of 12 kilometers from Mount Agung.

“Based on the inspection of our officers from the north and south of Mount Agung, until now the sulfur gas content is still zero,” said Head of PVMBG Volcanic Mitigation Division, Gede Suantika, at Gunung Agung Observation Post, Rendang Village, Karangasem, Sunday / 10/2017).

Measurement of the sulfur content of Mount Agung has been done since three days using a spectrometer tool. The tool is used for sampling sulfur content from the mountain from a distance of 12 kilometers from the crater lip.

Gede Suantika pointed out, the method of checking the sulfur content is highly dependent on the position and direction of the wind. If the sulfur gas distribution is carried by the wind to the west, then checks must be done in the west of Mount Agung and the spectrometer must be directed vertically (upward) north and south direction.

“If this gas passes over this spectrometer, it will be known to concentrate the sulfur gas content but it is still nil at a radius of 12 km, but based on the last climber’s information, a 700-meter radius from the crater lip already smells of sulfur,” he said. .

Meanwhile, Head of PVMBG, Kasbani, added that his side has added two tools tilmeter (new tool to detect deformation) to confirm the bloat of Mount Agung.

“This tool again functioned to anticipate the worst, due to the mounting of Mount Agung,” he said. The tilmeter tool is mounted on the north and south sides at a radius of 9 to 12 kilometers from the summit of Mount Agung.

Cause of Smoke

Yesterday, heavy rain continued to flush around Mount Agung.
The high rainfall around Mount Agung in the last few days is suspected to be a trigger puff of smoke as high as 1500 meters which appeared Saturday (7/10/2017) at around 20:40 pm.

“The smoke is still white and has not been mixed with the material,” said Suantika. “The smoke of 1,500 meters of smoke from the mountain peak is caused by the high rainfall around Gunung Agung during the last three days.

He explains, the smoke that soar can be triggered by the base of a very hot crater, then torrential rain. Accumulation of water down the crater, then released into water vapor that looks like white smoke

“So 99 percent of the smoke that yesterday was steaming high still contains water vapor, so the phenomenon yesterday night was not erupted, but still solfatara activity,” explained Suantika. Volcanoes can be said to be eruptions, says Suantika, if a cloud of smoke is concentrated and mixed with material from the bowels of the earth.

Yesterday afternoon, the Regional Disaster Management Agency (BPBD) of Klungkung, I Putu Widiada, and his staff seemed to visit the Observation Post to coordinate with PVMBG related to the high smoke occurrence on Mount Agung.

He revealed, many refugees in Klungkung questioned the event of a high smoke. Moreover, the highest smoke smoke since the status of Awas that many who perpetuate and be distributed in social media.

“Many people asked whether Mount Agung had erupted, after we met directly from Mr. Kasbani, it turned out that Agung Mountain has not erupted, the smoke is water vapor, we have printed out the explanation of the phenomenon, and we will attach it to GOR Swecapura Refugee Post , “said Widiada.

The evaluation of volcanic activity of Gunung Agung, Sunday (8/10/2017), shows the highest mountain in Bali is still in the status of Awas.

The condition of seismicity remains critical.

The number of deep volcanic earthquakes is still in the number 500-600 per day, while shallow volcanic earthquakes are at 300-350 per day, while local tectonic earthquakes are at 60-70 per day.

“From the seismicity, there are no signs of tremor yet, still an earthquake like before,” said Suantika. (*)
