Thoron, radon and microbial community as supportive indicators of seismic activity in groundwater.

ABSTRACT: Earthquakes have a significant impact on groundwater environments as well as human life. However, identifying active and affected zones from seismic events using isotopic and microbial diversity indicators remains a challenging frontier. To validate the applicability of this coupled method for real-time analysis, we analyzed thoron (²²⁰Rn), radon (²²²Rn), microbial community compositions, and hydrochemistry in groundwater samples during the 2017 Pohang earthquake for the first time. We observed the detection of ²²⁰Rn in groundwater right before the aftershocks, with a high correlation to ²²²Rn concentrations. This indicates that ²²⁰Rn and ²²²Rn can serve as reliable seismic indicators for real-time analysis. The microbial da
