A smoking volcano has forced an airport to close as experts warn a bigger eruption could be on the way.

Mount Bromo, on the island of Java in Indonesia, came back to life last week after a year-long lull, forcing the closure of the airport in Malang, which is 15 miles from the volcano, for five days.

While the volcano, which is a popular tourist attraction that can be climbed, unleashed a powerful blast, no-one was injured and there was no serious damage, However, experts are warning this could just be the beginning.

Indonesia has more volcanos than anywhere else in the world while Mount Merapi, also in Java, caused widespread evacuations and a flying ban when it erupted earlier this month.
