The latest earthquake rocked Indonesia, a country located on the Pacific Ring of Fire and known for its intense seismic activity. On September 28 2023, Indonesia experienced an earthquake measuring 6.2 SR with the epicenter located at a depth of 10 km, precisely around the sea near Nias Island, North Sumatra. This was an incident that sparked attention not only from the local community but also from the international community. The Meteorology, Climatology and Geophysics Agency (BMKG) immediately released an early warning to anticipate the potential for a tsunami due to the earthquake. Although worrying, the warning was lifted several hours later after further analysis was carried out. The affected areas cover a wide range of areas, including small towns located near the epicenter, with reports of minor damage to infrastructure. People in the surrounding area immediately rushed out of the buildings, remembering their previous experience with a large earthquake. Rescue news and information became one of the main priorities within a few hours after the incident. An evacuation team was formed to ensure the safety of residents in areas prone to earthquake impacts. Geophysicists explain that Indonesia’s geological conditions, which consist of the overlap of several tectonic plates, are the main cause of frequent earthquakes. This makes the country one of the most seismically active regions in the world. Meanwhile, education regarding earthquake preparedness is very important to reduce the risk of loss of life and property. In the next few weeks, experts will continue to monitor the impact of this earthquake, both in terms of the mental health of people who may experience trauma and damage to infrastructure that needs to be repaired. Local governments are also expected to carry out a comprehensive assessment of houses and buildings affected by the earthquake. In addition, rehabilitation and reconstruction efforts will be prioritized to help affected residents. Social media also plays an important role in disseminating information. Many citizens share their experiences through platforms such as Twitter, Instagram, and Facebook, adding narratives and realities to support each other. The community solidarity movement was also seen with various humanitarian actions to help those in need. There is an urgent need to redesign the earthquake and tsunami early warning system. Some scientists suggest that more investment should be focused on developing technology that can provide information more quickly and accurately. Research on earthquakes must be carried out on an ongoing basis, involving active community participation to increase awareness of seismic risks. Concern for the environment is also an integral part of disaster risk mitigation efforts. Planting trees and good land management in disaster-prone areas can contribute to reducing impacts. Therefore, it is important to increase collaboration between government, private institutions and civil society in dealing with the threat of earthquakes in the future.
