The South Lampung Regency #DisasterManagementAgency (BPBD), citing a September 3 #evaluation by the Geological Agency of #Indonesia’s Ministry of Energy and Mineral Resources, reported that Anak #Krakatau remained at Level III (Siaga).
The #evaluation described shallow or near-surface magma dynamics as very high and maintained a 3 km (1.9 miles) exclusion zone around the active crater.
During the August 22–31 monitoring period, the #GeologicalAgency recorded #eruption columns rising 50–400 m (164–1 312 feet) above the crater.
Sulfur dioxide emissions ranged from 715 to 2 922 tonnes (788–3 221 short tons) per day.
The monitoring network recorded 174 eruption earthquakes, 714 emission events, 336 low-frequency #earthquakes, 32 harmonic events, 851 hybrid or multiphase earthquakes and 30 periods of continuous tremor.
BPBD said potential hazards identified in the September 3 evaluation included incandescent ejecta and heavy ashfall near the #volcano.
Under the Geological Agency’s Level III recommendations, #fishermen, #tourists and #climbers were instructed to remain outside the 3 km (1.9 miles) exclusion zone and follow official #information.
