[20] The government issued the highest-level warning for the area, which was expected to remain in force for around a week, since scientists were unfamiliar with the characteristics of the volcano, due to it having been dormant for so long.

[23] In the wake of the eruption, the National Disaster Management Agency (Badan Nasional Penanggulangan Bencana/BNPB), supported the roughly 27,489 displaced people by providing shelters.

[24] The local government has allocated 50 tonnes of rice, 14,000 tins of fish, 1 water truck, 1,000 bottles of ketchup, 240 kg of instant noodles, 500 blankets, 50 family tents, 200 sleeping mats, oxygen bottles/tubes for emergency, and 5,000 packs of vitamin C and B6.

[26] More than 3,700 people were evacuated from areas within a 3 kilometre (2 mile) radius of the volcano, and five halls normally used for traditional cultural ceremonies were converted into shelters with at least 1,500 being temporarily housed.

[27] The Indonesian Center for Volcanology and Geological Hazard Mitigation advised villagers to keep a distance of at least 2 miles from the volcano, while 5,000 people were evacuated from North Sumatra Karo Regency.

[27] The eruption has affected the people living around the volcano in more than one way; crops died due to the ash fall leading to an economic change in the area.

[29] "Mount Sinabung, which has erupted over a hundred times between Jan. 4 through the morning of January 5 is spewing out a 4,000 metre (13,000 ft) high column of ash damaging property and crops and poisoning animals over a wide radius.

[30] Reports claim that at least 16[6] people died as a result of the eruption, which occurred just after residents living more than five kilometers from the mountain had been allowed to return home following a lack of recent volcanic activity.

[31] Seven of the victims were members of the Indonesian Christian Student Movement (GMKI), who died while trying to save local residents as pyroclastic flows swept across Mount Sinabung.

The Darwin Volcanic Ash Advisory Centre (VAAC) reported eruptions between 6 and 10 October, with some evacuations from surrounding villages.

[35] The Tourism Agency of the Karo regency has officially proposed several locations to local government as potential tourist sites.

[41] An eruption took place on 7 May 2019, sending a massive column of ash and smoke 2,000 meters (6,500 feet) into the air, coating local villages in debris.

Officials stated that the eruption had the potential to affect aerial flights, though they did not issue a formal advisory for planes to avoid the area at the time.

[42][14] A large eruption occurred on 9 June, at 04.28 p.m., local time, sending a plume of ash 7,000 meters (22,966 feet) into the air, and generating a pyroclastic flow 3‒3,5 kilometers long towards the south and southeast.

[49] No casualties were reported, but people were advised to stay at least three kilometers from the crater by Indonesia's Volcanology and Geological Hazard Mitigation Center.

[51] On 28 July 13:20 local time, Mount Sinabung erupted, sending a massive column of smoke and ash 4,500 meters (14,760 ft) into the sky.

It also generated pyroclastic flows that traveled down the eastern and southeastern flank for about 1000 m. An ecosystem responds to volcanism in many different ways depending on the frequency, scale, and severity of the eruptions.

[52] Furthermore, it can be assumed that the pyroclastic flow of the eruption, whose temperature was estimated at 700 °C (1,300 °F) by Indonesian officials, killed much of the organic matter including plants and animals.
