dc.description.abstract | A moment magnitude 5.4 earthquake struck the Pohang city located in the southeastern Korean Peninsula on 15 November 2017, possibly triggered by an enhanced geothermal system. Despite the moderate magnitude of the earthquake, extensive geotechnical and structural damage occurred. This study summarizes the widespread geotechnical damage resulted from the Pohang earthquake, observed during our reconnaissance trip. The affected area is mainly covered by Tertiary/Quaternary Alluvium underlain by mudstones with a thickness of approximately 500 m. Because of the soft grounds and shallow focal depth, this area experienced ground settlements up to 39 cm, building settlements that made apartments tilted by 1.6 degrees. We also present observations on ground cracks, lateral spreadings, landslides, retaining wall deformations, and liquefactions. Documenting the damage is significant because (1) those are the first earthquake-induced damage observed in Korea, and (2) those are caused by the shallow-depth earthquake possibly induced by an enhanced geothermal system. | - |
