The Geophysical Exploration Institute swiftly joined the emergency rescue efforts for the flash flood and debris flow disaster in Kangding.
At 3:30 a.m. on August 3, a sudden flash flood and debris flow struck the Guza Town area in Kangding City, Ganzi Prefecture, Sichuan Province, causing extensive damage to houses in Ridi Village, Guza Town. The affected area features deep layers of debris flow and numerous large boulders. As a result of the collapse of residential buildings, a large number of liquefied petroleum gas (LPG) cylinders were buried, posing significant potential hazards to rescue and emergency operations.

After the disaster occurred, the Geophysical Exploration Institute promptly responded to the request of Sichuan Resources Group, leveraging the non-invasive exploration advantages of geophysical techniques. It immediately established a special task force for emergency rescue and relief operations in response to the Kangding flash flood and debris flow disaster, dispatching experienced technical experts along with various instruments and equipment—including those capable of measuring inverse magnetic flux—on August 3 itself, swiftly heading to the affected area to join the rescue efforts.
According to the unified arrangement of the command center, the Geophysical Exploration Institute is primarily tasked with detecting liquefied gas tanks buried beneath debris flow deposits. Currently, based on geophysical resistivity profiles and magnetic survey data, key areas where the liquefied gas tanks are buried have been identified. In the next step, the institute’s technical personnel will consult with the command center to develop an on-site disposal plan, providing professional technical support for emergency rescue and disaster relief efforts and making every effort to ensure the safety of people’s lives and property.
