NTT - Center for Volcanology and Geological Hazard Mitigation (PVMBG) reported that the status of Mount Ile Lewotolok in Lembata Regency, East Nusa Tenggara (NTT), has increased its status from Alert to Alert.
Head of the Center for Monitoring of Volcano and Disaster Mitigation of the Land Movement of the Nusa Tenggara Region, Zakarias Ghele Raja, said the increase in status was due to a significant increase in activity.
"Based on the results of a thorough analysis and evaluation until February 26, 2024, it shows a significant increase in activity, so the activity level of Mount Ile Lewotolok starting from 27 February 2024 at 10.00 WITA is raised from Level II to Level III," he said when contacted, Tuesday, February 27, was confiscated by Antara.
He said this status increase was also determined based on the results of the evaluation of the development of volcanic activity in the mountain for the period Saturday, February 24 to Monday, February 26.
During that period, he continued, there was an eruption with an altitude of approximately 200 to 1,000 meters from the summit.
In addition, there were also avalanches, visually the distance and direction of the slide ranged from 300 to 1,000 meters from the summit with a sliding direction to the southeast to south region.
Even on February 15, new lava flows emerged both to the south and to the southeast as far as 400 meters from the crater's lips.
"As of February 26, the new lava flow has reached a distance of two kilometers to the southeast with a fairly fast lava flow rate," he said.
Meanwhile, based on seismic data in the period 16 to 26 February, 98 earthquakes were recorded due to eruptions, 30 earthquake avalanches, 3,615 earthquake gusts and 98 non harmonic tremors.
Until now, he said, explosive eruptions were still ongoing with the dominant lava coverage around the crater area, but could also reach 500 meters out of the crater.
