Residents living around the base of Indonesia’s Mount Egon were ordered to evacuate as the Flores Island volcano began to rumble because of rising magma.

A 2-mile exclusion zone was established around the 4,487-foot volcano, which last erupted in 2008, forcing more than 10,000 people to flee.

Egon is the only one of six volcanoes in Indonesia currently on an alert level of 3 or 4 that is not currently erupting.

The vast archipelago has 127 active volcanoes, more than any other country on the planet.
