JAKARTA, Indonesia » A smoking volcano on Indonesia’s main island of Java has forced the closure of a local airport.

Mount Bromo came back to life last week after a yearlong lull, unleashing a powerful blast of volcanic debris but causing no injuries or serious damage.

State volcanologist Surono warned, however, a bigger eruption may be on the way.

Officials on Monday shut down the airport in Malang, a town 15 miles (25 kilometers) from the volcano, for five days.

Indonesia, a sprawling archipelago of 235 million, has more active volcanoes than any other country in the world.

Mount Bromo is one of Java’s most popular tourist attractions.

Villagers often climb the 7,641 foot- (2,329 meter-) high mountain to leave offerings at the peak.
