Indonesia, an archipelago of more than 250 million people, sits on the Pacific "Ring of Fire" and is prone to earthquakes and volcanic eruptions. Government seismologists monitor more than 120 active volcanoes.
The latest lost homes were in addition to at least 117 others that were previously reported by officials since lava began spilling last month from cracks in the ground in a mostly rural district of the Big Island.
Guatemala's disaster agency, Conred, issued a number of standard precautions, advising people to wear protective face masks, clean their rooftops of ash once the eruption was over and cover any food and water intended for human consumption.
The bulletins also warned that reports of toxic sulfur dioxide gas being vented from various points around the volcano had tripled, urging residents to "take action necessary to limit further exposure."
Lusi, the world's largest mud eruption that began on the Indonesian island of Java in 2006, is not stopping any time soon as deep underground it is connected to a nearby volcanic system, scientists have determined.
Mount Sinabung is among more than 120 active volcanoes in Indonesia, which is prone to seismic upheaval due to its location on the Pacific "Ring of Fire,'' an arc of volcanoes and fault lines encircling the Pacific Basin.
The local disaster mitigation agency of Indonesia, said hundreds of residents were being evacuated from several villages, bringing the number of people moved in recent weeks to more than 3,000 since Mt Sinabung started spewing.
