500 people living on Indonesia's Mount Merapi have been evacuated following increased volcanic activity. Authorities warned the volcano could erupt at any moment.

Merapi lies only 18 miles Yogyakarta city centre, and 250,000 people live within 6 miles of the volcano, putting them at high risk should activity increase. Merapi sent ash and gas clouds as high as 3.7 miles into the air in June, although no casualties were reported at that time.

Indonesia's geological agency have raised Merapi's alert level to the second-highest level and local administrations are monitoring the situation closely.
