Bali Volcano Eruption: Scientists Stay Ready For Potential Big One

The Agung volcano in Indonesia was in the news recently for a recent spike in activity. The 3,000 meter (9842 feet) high, so-called strato-volcano has a history of very violent eruptions like the one in 1963 that killed more than 1,000 people.

Detecting a volcanic eruption is no easy business, and it requires monitoring very small vibrations and tremors on the Earth’s surface.

Seismic activity in and around volcanic regions are measured and any spike in activity is considered an indication of a future eruption.
