土壤气观测是近年来发展较快的地球化学观测手段,而土壤H2在区域中强地震前的数据变化尤为明显。2023年安徽省地震局在郯庐断裂带中南段的合肥庐江、滁州滁阳先后建立两个土壤H2观测站,通过优化断层气观测站建设方案,对集气装置材料进行升级改造,保证了集气装置的完整性和空间的有效性,进一步提高了数据真实性可靠性。其中滁阳土壤H2在2024年肥东序列地震中,多次记录到地震前后的数据异常变化,表明土壤H2在郯庐断裂带局部中强地震具有较好的短临预报效能,研究成果为土壤气站网建设提供技术方案,对郯庐断裂带的地震活动性监测具有一定的科学价值和促进作用。
- Abstract:

Soil gas observation has emerged as a rapidly advancing geochemical observation methode in recent years, with particularly pronounced data variations in soil H2(hydrogen)observed before moderate-strong earth?quakes in the region. In 2023,the Anhui Earthquake Agency successively established two soil H?observation sta?tions in Lujiang,Hefei,and Chuyang,Chuzhou,located in the central-southern segment of the Tanlu fault zone. By optimizing the construction plan for fault gas monitoring stations and upgrading the materials used in gas collec?tion devices, the integrity and spatial effectiveness of the gas-gathering system were ensured, further improving the authenticity and reliability of the collected data. Notably,the soil H?data at the Chuyang station recorded multi?ple abnormal variations before and after the 2024 Feidong earthquake sequence,indicating that soil H?exhibits fa?vorable short-term to imminent prediction efficiency for local moderate-strong earthquakes along the Tanlu fault zone. The research results provide a technical framework for the construction of soil gas monitoring networks and have certain scientific value and promotion effect for seismic activity monitoring along the Tanlu fault zone.
