The biggest earthquake that rocked Indonesia this year occurred on August 14 2023. With a magnitude of 7.0, this earthquake was centered in waters about 50 km from the city of Palu, Central Sulawesi. Based on reports from the Meteorology, Climatology and Geophysics Agency (BMKG), the depth of the earthquake reached 10 km, which made the impact felt significant. The Palu area, which experienced a similar natural disaster in 2018, is again exposed to high risk in this earthquake. According to the latest data, more than 5,000 houses were damaged by severe shaking, and thousands of residents were forced to flee to safer places. The authorities immediately sent a SAR team to evacuate and provide assistance to the victims. The earthquake also had an impact on seismic activity throughout Indonesia. Aftershock activity with smaller magnitudes continued to occur several days after the incident. The team of geophysicists from BMKG reminded that Indonesia is located on the Pacific Ring of Fire, so earthquakes are often a threat. The public is advised to increase vigilance and prepare themselves for the worst possibility. The local government has activated the emergency response system, and volunteers have gone into the field to provide basic needs such as food, clean water and protection for those affected. Humanitarian organizations have also begun to mobilize, raising funds and donations to help the recovery of affected areas. In an effort to educate the public, BMKG launched an outreach program explaining the importance of understanding earthquakes and how to survive them. Information about how to save yourself during an earthquake, such as taking cover under a table or staying away from windows, is increasingly being provided through social media and community seminars. On the other hand, damaged infrastructure is a big challenge. Main roads and public facilities suffered extensive damage, hampering access to aid and recovery. In particular, the education sector was also affected, with many schools experiencing damage, forcing students to look for temporary places to study. As a precautionary measure, the government is planning to rebuild infrastructure that is more earthquake resistant. This project prioritizes building designs that take into account the geological aspects of the region to reduce the impact of future disasters. Data from the Indonesian Institute of Sciences (LIPI) shows that the increase in earthquake frequency is influenced by tectonic activity. Seeing this situation, further research in the field of geophysics is very necessary. It is key to understanding seismic patterns and mitigating future risks. The resilient attitude of society remains in the spotlight. Despite the huge trauma and loss, many local residents showed courage and passion to rebuild their lives. With a spirit of mutual cooperation, recovery efforts will be faster and more effective. As time goes by, it is hoped that the lessons from this earthquake will increase awareness not only in Central Sulawesi, but also throughout Indonesia. Community-based approaches to rehabilitation and outreach are critical in building resilience to future earthquakes. Through collaboration between government, scientists and society, mitigation efforts can be strengthened.
