The impact of a major earthquake on the global economy can be very significant, affecting various sectors from trade to investment. Directly, earthquakes cause damage to infrastructure, such as buildings, roads and bridges, which can hamper connectivity and mobility. To date, material losses due to natural disasters often reach billions of dollars. Repair and reconstruction costs are a long-term burden for the government and society. The industrial sector was the most affected by the earthquake. For example, if a factory experiences damage, production of goods will experience delays, which ultimately affects the global supply chain. When one country is forced to stop production, other countries will feel it, especially if they depend on components or raw materials from the affected country. This results in product inflation and price increases in international markets. The impact of the earthquake also created uncertainty in financial markets. Investors tend to withdraw their investments from disaster-prone areas, resulting in a decline in share values and inflation. Additionally, countries are sinking into debt after spending huge amounts on recovery. This poses a risk to global economic stability, especially in developing countries with limited financial reserves. Tourism, an important part of some countries’ economies, could also be hit hard. When an area is hit by a disaster, the perception of risk increases, making visitors think twice about vacationing there. This not only reduces revenues from the tourism sector, but can also lead to the closure of related businesses, such as hotels and restaurants, which are often the driving force of the local economy. Sustainable development becomes a major challenge after a major earthquake. Reconstruction efforts are often faced with a dilemma between rebuilding old infrastructure and creating more disaster-resistant solutions. For example, investing in green technology and sustainable buildings can be a long-term solution, but requires high initial costs. The community also needs to be involved in the planning process in order to increase resilience to future disasters. Facing all this, international cooperation is crucial. Other countries often provide assistance in the form of funds, resources, or experts to aid recovery. This support not only speeds up the reconstruction process, but also helps stabilize the affected global economy. In some cases, international organizations such as the UN have had a positive impact, by mobilizing resources to help countries devastated by earthquakes. Finally, the post-earthquake global economic impact shows how interconnected the world is today. Each disaster not only affects the affected country, but also triggers a chain reaction that can shake the global economy. Fast, strategic and sustainable treatment is needed to minimize losses and ensure effective recovery.
