Global earthquakes are natural phenomena that have a significant impact on human life and environmental conditions throughout the world. Earthquakes occur when there is a sudden release of energy beneath the Earth’s surface, often due to the movement of tectonic plates. This phenomenon is not only able to change the physical landscape, but can also influence the economy, social and culture of an area. The main cause of earthquakes comes from tectonic activity. The plates in the Earth’s crust move at very slow speeds, but when the accumulated stress becomes too great, the plates will move suddenly, causing shaking. There are various types of earthquakes, such as tectonic, volcanic and landslide earthquakes, each with different causes and impacts. Earthquakes can cause major destruction. In 2010, an earthquake in Haiti resulted in more than 230,000 deaths and extensive infrastructure damage. This incident shows how vulnerable society is to natural disasters. Additionally, tsunamis, which often occur after undersea earthquakes, can add to the destructive impact. For example, the tsunami that followed the Indian Ocean earthquake in 2004 claimed more than 230,000 lives in several countries, including Indonesia, Thailand, and India. The positive side of earthquake research is technological advances in predicting earthquakes. A number of countries are investing in early warning systems that can provide valuable information in seconds. This technology can save many lives by giving people time to evacuate. Earthquakes also have psychological impacts. Victims experience prolonged trauma, sadness and anxiety. Mental recovery often takes months or even years, requiring attention and support from various parties. From an economic perspective, an earthquake can destroy a country’s economy. Damage to infrastructure, loss of assets, and reduced work productivity have an impact on long-term economic growth. For example, Japan, after the 2011 earthquake and tsunami, faced reconstruction costs running into hundreds of billions of dollars. As part of global earthquake studies, it is also important to research earthquake-prone areas. Countries such as Japan, Indonesia and Chile are in the Pacific ring of fire, which is known as a zone of high seismic activity. Education regarding disaster mitigation is very important to reduce risks in the area. Investment in earthquake-resistant infrastructure is an important step. Countries frequently hit by earthquakes need to formulate building policies that prioritize safety. Building designs must be adapted to seismic standards that are able to withstand strong shaking. Public awareness about the dangers of earthquakes must also be increased. Evacuation training and increasing knowledge about appropriate actions during an earthquake must be an integral part of education. Earthquakes are a phenomenon that cannot be avoided, but understanding and preparing can help reduce the impact. The use of technology, good policies and public education are the keys to dealing with earthquakes in a global context.
