JAKARTA - The Ministry of Energy and Mineral Resources (ESDM) reminds the public, visitors, tourists, and climbers not to carry out activities or approach areas within a radius of 1.5 kilometers from the Tompaluan-Gunung Lokon crater in Tomohon City, North Sulawesi (North Sulawesi).
"Based on the results of thorough analysis and evaluation until May 15, 2026, the level of activity of Mount Lokon is still at Level II (Warning)," said Acting Head of the Geological Agency Lana Saria in a report on Mount Lokon's activities, Sunday, quoted by Antara.
Based on instrumental observations, the seismicity during the period 1-15 May 2026 was recorded as 33 times of eruption earthquakes, 54 times of shallow volcanic earthquakes, seven times of deep volcanic earthquakes, and 98 times of distant tectonic earthquakes.
Based on visual observations of Mount Lokon activity, a thin white plume of smoke was observed with a maximum height of about 25 meters above the crater. The flame was also seen at the bottom of the crater on May 15, 2026.
The seismicity of Mount Lokon is dominated by shallow volcanic earthquakes (VB), while deep volcanic earthquakes (VA) are rarely recorded.
Volcanic activity based on visual and seismic data has not shown any increase.
Meanwhile, the potential danger of Mount Lokon's current activity is the possibility of toxic gas coming out of the crater.
In addition, phreatic eruptions, which are eruptions caused by the contact between hot steam of magma and hydrothermal water, can also occur suddenly.
"People who are around the river channel that flows at the top of Mount Lokon should be aware of the possibility of lahar during the rainy season or when heavy rain lasts for a long time in the peak area," he said.
