The 1955 Zheduotang earthquake, also known as the Kangding earthquake occurred on April 14 at 09:29:02 local time near the city of Kangding in the Garzê Tibetan Autonomous Prefecture, Sichuan. The earthquake had a moment magnitude of 7.0 and a surface wave magnitude of 7.1 and struck at a depth of 10 km.[1] Severe damage occurred in Kangding with the loss of 70 lives.

The
Characteristics
The earthquake specifically ruptured the Zheduotang Fault; a segment of the Xianshuihe fault system. The left-lateral
Coulomb stress transfer after the 1955 earthquake increased seismic strain on the adjacent Selaha Fault, also part of the Xianshuihe fault system. In 2014, an earthquake measuring magnitudes 5.9 ruptured the Selaha Fault, releasing some of the strain.[7] Since the 1955 quake, the Zheduotang Fault has accumulated enough strain to generate a magnitude 6.5–6.8 earthquake with the potential to cause severe destruction.[8]
Damage
Many landslides were triggered and the ground fissured. Natural springs erupted water intensely or dried up. Spring water discolored after the quake. A total of 624 homes and temples were destroyed and 1,083 were damaged in Kangding. At least 70 people died and 217 were injured.[9] Walls around the city toppled. Approximately 90% of the city's wooden-frame or adobe-constructed structures were destroyed. There were more than 30 landslides recorded, many of which blocked roads. In Luding County, shabby homes collapsed. Bridges, dams and ravines were seriously damaged or collapsed.[10] Landslides affected an area of 4,416 km2.[11]
