Indonesia’s Mount Merapi
Authorities in West Sumatra have raised the alert level of Mount Marapi after the volatile volcano began spewing clouds of hot ash late on Saturday.

Pyroclastic clouds over the volcano's dome were first spotted at 10.33 p.m. on Saturday, officials from the Marapi observation post told local media. The activity continued well into Sunday morning. The same post also reported a series of minor seismic quakes.

The eruption is considered fairly minor but authorities have issued a warning to locals and hikers to stay beyond a three-kilometer radius from Marapi's crater. Authorities also elevated the mountain's status to the second highest alert level.

The volcano registered a similar eruption on April 13.
