Indonesia has been hit by more volcanic activity following a series of eruptions last month that killed 24 climbers.

Residents near Mount Marapi in West Sumatra province report hearing a loud boom on Sunday before the mountain again erupted. The explosion sent a cloud of smoke and ash up to one kilometer into the sky.
This was followed by ash rain which inundated the mountain's slopes.

The eruption forced dozens of residents to evacuate. Officials are advising people to take cautionary measures, including wearing masks and staying clear of the mountain. They are also warning people to beware of lava possibly flowing into rivers.
Meanwhile, Mount Lewotobi Laki-laki on the country's Flores Island has also seen a surge in volcanic activity following an eruption in December.
The increasing volcanic activity has resulted in 6,500 residents fleeing their homes.
Authorities say many people staying in shelters are now suffering from a variety of respiratory infections.
