JAKARTA - The Center for Volcanology and Geological Hazard Mitigation (PVMBG) reported that the eruption of Mount Ruang which occurred early this morning damaged a seismic station that functions to record various volcanic seismic activity.
Bumi Madya Investigator Hetty Triastuty said the seismic station was built on the coast of Ruang Island, which is about two kilometers from the center of the active crater.
"Our tool died not long after the eruption incident this morning," he said as quoted by ANTARA, Tuesday, April 30.
Hetty said that although the seismic station on Ruang Island was damaged by the eruption, her party still had a seismic station at the volcanic observation post located on Tagulandang Island.
The seismic station, which is still operating on the island of Tamulandang, is further away than the equipment on the Island of Ruang.
However, PVMBG also received assistance from several volcanic observation posts in North Sulawesi and Maluku.
"Currently ( volcanic activity and seismicity) shows relatively calmer than last night and early this morning," concluded Hetty.
Mount Ruang seismic station was once damaged by an eruption that occurred on April 17, 2024. The Geological Agency team installed a replacement station at the Mount Ruang observation post and began operating on April 20, 2024.
Mount Ruang has a peak height of 725 meters above sea level and at the same time forms a separate island from another island.
The mountain, which is type strato with the lava dome, is administratively located in Tulusan Village, Tagulandang District, Sitaro Regency, North Sulawesi.

On April 1 to 28, 2024, the number of seismicities was recorded at 6 earthquake eruptions, 15 earthquake avalanches, 1 tremor earthquake, 1 non harmonic tremor earthquake, 3 tremors, 2,057 earthquakes. deep volcanic earthquake, 1,018 shallow volcanic earthquakes, 32 local tectonic earthquakes, and 195 distant tectonic earthquakes, and earthquakes were felt 7 times on the MMI scale.
Meanwhile, the number of seismicities recorded through the seismic station on April 29, 2024, from 00.00 to 24.00 WITA, was in the form of 15 avalanches, 237 shallow volcanic earthquakes, 425 deep volcanic earthquakes, 25 local tectonic earthquakes, and 6 distant tectonic earthquakes.
The number of eruptions that occurred today, the period from 00.00 to 12.00 WITA occurred three earthquakes with an amplitude of 55 millimeters and an earthquake duration of 360 to 600 seconds. PVMBG also noted that there were two continuous tremors with an amplitude of 20 to 55 militaries.
