Horizontal slices of V s perturbation at depths of 6, 12, 18, 24, and 40 km. Star denotes the epicenter of the 2008 main shock. White circles and small crosses denote the aftershocks and other microearthquakes (1997–2007). White rectangular denotes the horizontal projection of the aftershock area, and the areas with less aftershocks are shown by broken lines. White small crosses at a depth of 24 km denote low-frequency earthquakes.
