A volcano on the popular tourist island of Bali could erupt for the first time in decades.
A spokesperson for Indonesia's national disaster agency told reporters hundreds of shallow volcanic earthquakes were recorded on Mount Agung in recent days. He said an eruption is a "definite possibility."
But experts say there's no way to predict exactly when that could happen.
The last time Mount Agung erupted was in 1963. More than 1,000 people were killed.
Authorities say the volcano doesn't pose an immediate threat to tourists. But several countries, including the U.S., the U.K. and Australia, have warned their citizens against traveling to Bali in case of an eruption.
