The latest earthquake was recorded in the Indian Ocean with a significant magnitude, attracting the attention of many parties, especially in areas at high risk of earthquakes. On a certain date, an earthquake measuring 7.0 on the Richter Scale occurred near Sumatra, Indonesia. This incident is important research for seismologists and local governments because it creates the potential for a tsunami and impacts on residents. The Indian Ocean region often experiences seismic activity because of its geographical location close to several tectonic plates, including the Indo-Australian Plate and the Eurasian Plate. This phenomenon causes faults to occur which makes earthquakes occur quite frequently in the area. Earthquake parameters are measured using seismometers, which are capable of detecting ground vibrations even on a very small scale. The epicenter of the famous earthquake was in the Pacific Ring of Fire region, which includes the Indian Ocean. When an earthquake occurred, the Indonesian Meteorology, Climatology and Geophysics Agency (BMKG) immediately provided a report and early warning to the public. Rapid assessment via seismic data helps determine the potential for a tsunami due to the earthquake. Coastal communities are advised to remain alert and comply with evacuation procedures if necessary. After the main earthquake, there is usually subsequent seismic activity, known as an aftershock earthquake. While some are smaller, some aftershocks can harm building structures that have already suffered damage from the main earthquake. Therefore, it is important for residents in vulnerable areas to understand safety measures during an earthquake. Analysis of the impact on the environment and infrastructure is often carried out after an earthquake. Buildings that do not meet earthquake-resistant standards are at high risk of collapsing. This makes it important to build sustainable development and apply safer construction technologies in earthquake-prone areas. Education about disaster mitigation is also characterized as a long-term strategy to reduce future risks. Further studies of earthquake events in the Indian Ocean, including historical data, show recurring patterns. This research provides valuable insight for scientists in understanding earthquake behavior and predicting possible future events. Communities in coastal areas, including fishermen and traders, are directly affected by a potential tsunami. Therefore, fast and accurate access to information is essential to save lives and reduce economic losses. Routine training and evacuation simulations are part of the government’s efforts to increase community preparedness. Continuous monitoring through seismic stations and the use of advanced technology are key in managing earthquake disasters. In recent years, many countries in the region have invested in integrated early warning systems, enabling faster and more efficient responses when disasters occur. Official information sources such as BMKG have a very important role in providing the latest information to the public. Accurate and updated earthquake data can help reduce panic and provide clear guidance for the public in dealing with emergency situations.
