KUPANG - Ile Werung Volcano in Atadei District, Lembata Regency, East Nusa Tenggara, has increased activity from level I or normal to level II or alert after an eruption or boasting on the underwater volcano Mount Hobal.
"Today, Monday, there is a visual increase in complex volcanic activity at Ile Werung volcano, although a significant increase in seismicity has not been observed", said Head of the Geological Agency, Head of the Center for Volcanology and Geological Hazard Mitigation (PVBMG), Andiani, quoted by Antara from a written statement, Monday, November 29.
However, although there has not been a significant increase in seismicity, she said there are recordings of volcanic earthquakes that indicate the movement of magma to the surface.
Therefore, although the current activity is not yet high, it has the potential to be followed by a larger eruption if the magma pressure increases significantly.
Andiani also explained the increase in activity that occurred and was observed on the surface in the form of gibberish.
"However, other activities such as lava flows may occur under the sea about 300 meters from the shoreline", she said.

Based on the latest monitoring data, there is a potential hazard in the form of underwater lava flows and material ejections around the boasting area.
Andiani added that the impact of volcanic activity could be an increase in sea level around the eruption center area.
"Other potential threats can be in the form of toxic volcanic gases such as CO2, CO, and SO2 in the area around the bubble", she said.
Regarding Ile Werung itself, the last eruption occurred on August 20, 2013, which was centered in an underwater volcanic crater.
At that time the eruption occurred with a column height of about 2,000 meters from sea level followed by flares of fire at sea level.
With this incident, the community is advised not to move around the coast, especially around the mountain location, or also prohibited from going to sea or sailing around the mountain.
