Coulomb stress changes associated with the M7.3 Maduo earthquake and implications for seismic hazards

Natural Hazards Research, 2021
On May 21, 2021, the M7.3 Maduo earthquake occurred within the Bayan Har Block, one of the most seismically active regions in the Tibetan Plateau. This aroused attention to the seismic hazards in this block. Understanding the stress transfer to adjacent faults is important for assessing seismic hazards.
