The 1,584m volcano, situated on Flores island, is part of a twin-peaked formation with the taller and less active Mount Lewotobi Perempuan. The eruption occurred at 11.05am local time, according to Indonesia’s volcanology agency, which noted that clouds of searing gas cascaded down the slopes during the blast.

Bali-bound holiday-makers can cautiously proceed with their travel plans after facing flight delays and cancellations due to two days of powerful volcanic eruptions in eastern Indonesia.
