Global earthquakes and climate change have a relationship that is increasingly being studied by scientists. Although earthquakes are generally viewed as a geological phenomenon that occurs as a result of shifting tectonic plates, environmental factors such as climate change can also influence seismic activity. In this section, we will explore the impact of climate change on seismic activity. One of the main aspects of climate change is an increase in global temperatures which causes the melting of ice in the polar regions. This melting reduces the pressure on tectonic plates which were previously stressed by the weight of the ice sheet. Pressure drops can trigger earthquakes, especially in geologically active areas. Research shows that regions such as Greenland and Antarctica experience increased seismic activity after the ice melts. Furthermore, changes in rainfall patterns due to climate can also trigger earthquakes. Increased rainfall can change the distribution of water on the surface and change the additional load on the earth’s crust. This change in weight can trigger local earthquakes, because the lower rock layers can experience an uneven increase in pressure. This is also a major concern in areas known for high seismicity. One prominent example is the earthquake that occurred in Christchurch, New Zealand, which was studied by seismologists. Researchers found that high rainfall before the earthquake occurred could be related to seismic activity. This shows that apart from geological factors, meteorological conditions also play a role in creating vulnerability to earthquakes. Climate change is also slowing down a geological process known as “glacial isostatic adjustment.” When the ice melts, the ground surface will begin to slowly rise again as the weight is removed. This phenomenon often causes cracks in the earth’s crust which can cause mild earthquakes. On a long-term scale, this process is important to understand, given its impact on plate interactions. In a broader framework, climate change can influence global earthquake risk by influencing the frequency and intensity of disasters. Rising temperatures can change underground drainage, thereby increasing seismic behavior in unpredictable areas. Further research is needed to better understand the long-term impacts of climate change on seismic activity patterns. Therefore, it is important for scientists and policymakers to consider the interactions between earthquakes and climate change in disaster risk models. Better understanding will create more effective and adaptive mitigation strategies in facing seismic challenges in this era of climate change. Interdisciplinary research spanning geology, climatology, and public policy is urgently needed to capture the complexity of these relationships.
