Asperity

Since rapid permanent plate shortening is not observed in subduction zones, there must be either strain release over a large region or strain accumulation over a small region over earthquake cycles. […] The most likely mechanism for the latter is the accumulation of elastic strain around isolated locked asperities of the fault, which requires significant aseismic fault slip between asperities.

The model to explain the seismicity variation along the fault boundaries considers that plate boundaries consist of asperities and barriers having different friction laws. These asperities are distributed in a fractal manner and each fault contains small and large asperities.
