An ERT profile scanned in areas with positive residual anomalies. A 400-meter-long ERT survey was conducted along Engineering Avenue on the NCKU campus. The profile revealed several low-resistivity zones extending from the surface to deep underground, indicating mud intrusion from depth to shallower levels. We drilled a 100-meter borehole (AT1) at the hotspot of the low-resistivity zones and a 20-meter borehole (BH3) some distance away from core AT1.
