Real-time monitoring system installed at Wongwian Yai following tunnel-related subsidence. • Location: Wongwian Yai, Bangkok • Notes: System uses high-precision sensors to monitor building tilt and ground movement, with data transmitted to a central platform and automatic alerts issued if structures exceed safety thresholds. Situation stabilized after chemical grouting reduced water inflow into the tunnel. Monitoring will continue until the area is confirmed safe.
