LUMAJANG, 4 September (BelTA - ANTARA) - Mount Semeru, Java’s highest volcano at
3,676 meters above sea level, erupted again on Thursday, spewing thick
volcanic ash southwestward from its crater.
The latest eruption occurred at 09:28 a.m. local time, sending ash columns 500 meters above the summit, or 4,176 meters above sea level, according to Mukdas Sofian from Semeru’s monitoring post.
The plume was white to gray with dense intensity, recorded on seismographs with a maximum amplitude of 22 mm and a duration of 145 seconds.
Earlier the same morning, at 05:01 a.m., Semeru also erupted, though it was not visually observed.
Seismic data showed a similar amplitude and lasted 140 seconds.
Semeru’s daily activity remains high, with 45 eruption quakes recorded on Wednesday, ranging from 10-22 mm in amplitude and lasting about 50-179 seconds.
The volcano is still on Alert Level II (Waspada). Indonesia’s Geological Agency has prohibited all activities within 8 km of the crater, particularly along the Besuk Kobokan river channel.
