Indonesia's recent volcanic eruptions are part of natural tectonic processes and not linked to global warming, say experts. Enhanced media visibility may be creating a perception of increased activity.

Indonesia's Mount Lewotobi Laki Laki erupted with giant ash and smoke plumes again Wednesday after forcing evacuations of villages and flight cancelations, including to and from the resort island of Bali.

Air India, Singapore ’s TigerAir and China’s Juneyao Airlines also suspended flight operations “due to volcano”, Bali’s international airport said. It forced dozens of residents living in two villages near the volcano to evacuate their houses, officials at the local disaster mitigation agency said.
