What kind of volcano is Agung?

Agung is classified as a Stratovolcano in Indonesia. Its tectonic setting is Subduction zone / Continental crust (> 25 km).

How is seismicity near Agung monitored here?

Earthquakes within 50 km of the crater are aggregated from 18 seismic networks and checked against a swarm rule that compares the current rate with this volcano's own 30-day background. Ash advisories come from the VAAC centres that are connected.

Volcano Agung

Bali's highest and most sacred mountain. Its 1963 eruption killed more than 1,100 people and measurably cooled the planet. When it stirred again in 2017, intense earthquake swarms led to the evacuation of about 140,000 people, and ash closed Bali's airport later that year.
