论文摘要
最近，余震的物理学已被三个新问题所丰富。我们将有条件地称它们为动态，逆和形态学问题。动态问题是寻找地震主要冲击后出现的圆世界地震回声的累积效应。根据该理论，主冲击激发了主冲击激发的表面地震波在主冲击后约3小时返回中心，并刺激强烈的余震的激发。第二个问题是对余震流的平均演变的足够描述。我们引入了一个关于地震来源停用系数的新概念，并提出了一个描述余震演变的方程式。基于进化方程，我们提出并解决了地震来源物理学的反问题。第三个任务是对余震的时空分布进行建模。它的解决方案完善了我们对地震来源结构的理解。
Recently, the physics of aftershocks has been enriched by three new problems. We will conditionally call them dynamic, inverse, and morphological problems. Dynamic problem is to search for the cumulative effect of a round-the-world seismic echo appearing after the main shock of earthquake. According to the theory, a converging surface seismic wave excited by the main shock returns to the epicenter about 3 hours after the main shock and stimulates the excitation of a strong aftershock. The second problem is an adequate description of the averaged evolution of the aftershock flow. We introduced a new concept about the coefficient of deactivation of the earthquake source, and proposed an equation that describes the evolution of aftershocks. Based on the equation of evolution, we posed and solved the inverse problem of the physics of the earthquake source. The third task is to model the spatio-temporal distribution of aftershocks. Its solution refines our understanding of the structure of the earthquake source.
