我们已经开发了一个正演模拟技术，以恢复破裂特征的小地震（3为每一个事件使用的解决故障长度。结果表明，大的变化范围从0.01到90 Mpa，与力矩无关。然而，Δ σ似乎与破裂速度Vr呈负相关;特别是，具有较大Δ σ的事件倾向于以较小Vr传播，而具有较小Δ σ的事件传播得更快。[1]：/embed/inline-graphic-1.gif
We have developed a forward modeling technique to retrieve rupture characteristics of small earthquakes (3 for each event using the resolved fault length. The results show large variations ranging from ∼1 to 90 Mpa, with no dependence on moment. However, Δσ appears inversely correlated with rupture speed V r ; in particular, events with larger Δσ tend to propagate at smaller V r , whereas events with smaller Δσ propagate faster.
