Bimodal seismicity in the Himalaya controlled by fault friction and geometry

Bimodal seismicity in the Himalaya controlled by fault friction and geometry

There is increasing evidence that the seismicity of large Himalayan earthquakes can be bimodal, but the underlying mechanisms are unclear. Here, the authors present a model and show that the bimodal seismicity results from a relatively higher friction and a non-planar geometry of the Himalayan megat...
