Earthquakes, an unpredictable natural phenomenon, have a significant impact on various aspects of ecosystems. This event caused a physical shift on the earth’s surface, which affected the habitat, flora and fauna. When an earthquake occurs, the resulting vibrations can damage the existing ecosystem structure. First, habitat destruction is a major issue. Earthquakes often cause landslides, which can block river flows and trigger floods. This damages the soil environment, changes the chemical and physical composition of the soil, and endangers the flora that depend on the ecosystem. Flora such as trees, plants and various species of fungi can lose their homes. Second, the impact on wildlife is also stark. Land movement and flood triggers disrupt animal migration routes, making them lose access to food sources and nesting sites. Endangered species could decrease in number, disrupting food chains and ecosystem balance. For example, bird species that depend on forest areas for nesting could be threatened if their habitats are destroyed. Third, environmental pollution due to earthquakes is very likely to occur. Chemical leaks from industrial facilities or storage tanks can contaminate soil and groundwater. Coastlines are also affected, especially if an earthquake triggers a tsunami, which can carry pollutants from land to the beginning of the sea, disrupting marine ecosystems. A concrete example is the increase in plastic concentrations in the sea after earthquakes and tsunamis, which has a direct impact on marine life. Fourth, earthquakes can trigger volcanism. If an earthquake occurs near a volcanic area, the increased pressure can trigger a volcanic eruption, releasing ash and dangerous gases into the atmosphere. This not only pollutes the air, but can also cover agricultural areas, reduce soil quality, and reduce crop yields. Fifth, decreasing water quality is also a serious problem. Earthquakes can damage water supply systems, destroy infrastructure, and cause water pollution. This has a negative impact on plants and animals that depend on clean water sources to survive. From a long-term perspective, post-earthquake ecosystem recovery requires time and effort. Habitat rehabilitation is an important step to return species and ecosystems to their original condition. Replanting local plants and sustainable management of affected areas is very necessary to ensure the survival of the ecosystem. Through a deeper understanding of the impact of earthquakes on ecosystems, we can develop better mitigation strategies. Continuous research in this field is important to protect biodiversity and maintain environmental balance in the face of natural threats. Therefore, collaboration between scientists, government and local communities is the main key in this effort.
