Open Badan Geologi ↗Reported level is not an independently verified all-clear. MAGMA is also linked below; its availability is independent of this feed.
Absence from a feed does not establish that no ash is present.
Rock fracturing and moving fluids create different seismic signals. A change in counts is interpreted alongside other evidence.
Ground movement can indicate pressure changes. Instruments measure small displacements; a swollen 3D mountain would require a stated exaggeration.
Gas composition, emission rates and heat can help identify changing pathways or magma supply. Weather can limit observations.
