• Indonesia's Mount Semeru erupted, prompting an aviation warning and a 3-kilometer danger zone declaration.
• This follows a series of volcanic activities across the country, including eruptions at Mount Lewotobi Laki-Laki and Ibu volcano.
• The eruptions have led to evacuations, with nearly 2,000 people taken to shelters.
• The recent eruptions highlight the vulnerability of human settlements to such disasters and the resilience of the Indonesian people.

Indonesia's Mount Semeru, located in East Java province, erupted on Sunday, causing the country's Center for Volcanology and Geological Hazard Mitigation to issue an aviation warning. The eruption sent a thick column of white-to-grey ash up to 1,000 meters into the sky, drifting northeast from the crater. This prompted authorities to issue the second-highest aviation warning, an orange Volcano Observatory Notice for Aviation, restricting flights within 5 kilometers of the volcano.

The eruption has led to the declaration of a 3-kilometer danger zone, with the southeastern area of the volcano having a designated danger radius extending up to 8 kilometers from the crater. Beyond these areas, residents have been prohibited from engaging in any activities within 500 meters of rivers originating from the volcano's slopes due to potential lava flows and hot clouds possibly extending up to 13 kilometers.

Mount Semeru, standing 3,676 meters high, is one of Indonesia's 127 active volcanoes. This recent eruption follows a series of volcanic activities across the country.

Indonesia's Volcanic Activity: A Series of Eruptions

On November 3, Mount Lewotobi Laki-Laki erupted, killing nine people and forcing thousands of locals to evacuate. The eruption resulted in the cancellation of more than 160 flights to and from Bali, disrupting the lives of many. To facilitate emergency relief efforts, the local government declared an emergency status from November 4 until December 31.

In May, the Ibu volcano on Halmahera Island in the eastern Indonesian province of North Maluku erupted. The Ibu volcano has erupted more than 80 times since the beginning of this year, causing significant disruption and damage. In April, Mount Ruang volcano erupted. The 725-meter-high volcano is one of Indonesia's most active. Mount Ruang last erupted in 2002, spewing out pyroclastic flows that damaged the land and local settlements.

Indonesia is home to roughly 500 mountains that dot the archipelago, of which 127 are active volcanoes. Dozens of them have been showing signs of increased activity. The country sits on the Pacific 'Ring of Fire' - an area abundant in volcanoes and seismic activity because it is directly above several tectonic plates.

Impact and Aftermath of the Eruptions

The recent eruptions have covered villages in a thick layer of volcanic ash. Authorities are still collecting data on the number of evacuees and damaged buildings. The latest event follows a series of eruptions of different volcanoes across the country. The country's location on the Pacific Ring of Fire, an area of high seismic activity atop multiple tectonic plates, makes it prone to such disasters.

The eruptions have also led to the evacuation of thousands of people. The National Disaster Mitigation Agency (BNPB) reported that 1,979 people were taken to 11 shelters, with at least six villages affected by the eruption. Images on local TV showed evacuees, mostly women, and children, taking shelter in a school. Most residents in the two most-threatened villages have evacuated themselves, said Patria Dwi Hastiadi, spokesperson of the Lumajang Disaster Mitigation Agency.

The internet in the area around Semeru was cut and phone signals were patchy after the eruption. The local rescue agency distributed free masks to the public because of the threat of polluted air to vulnerable residents. As rescuer Gunawan, who has the same name as the PVMBG spokesperson, filmed clouds above him in East Java after the eruption, a video showed the sky quickly turning to black as a colossal plume of ash engulfed any light.

The recent eruptions are a stark reminder of the power of nature and the vulnerability of human settlements in the face of such disasters. As Indonesia continues to grapple with the aftermath of these eruptions, the world watches with bated breath, hoping for the safety and well-being of those affected. The resilience of the Indonesian people is being tested once again, as they face the daunting task of rebuilding their lives in the wake of these natural disasters.
