文摘

We model the Coulomb stress changes imparted from the 2015 Nepal earthquake and its major aftershocks. We calculate the long-term and short-term seismic rate along the Himalayan Main Thrust fault. Our result shows good correlations between Nepal earthquake’s aftershocks and its stress-enhanced region. High seismic hazard is expected at the fault patches near the ruptured patches in the next few decades.
