Experimental data pertaining to weak faults requires construction of microscopic models of the earthquake sources. This study proposes a new high-energy mechanism of transformation of potential energy of strata, saturated with free or bounded fluids, into a kinetic energy of motion of rocks. The proposed approach relies within the framework of classic statistical theory. The high-energy phenomena at a nanometer level are generated by self-consistent molecular fields acting on individual particles. The analysis is carried out using the Bogolyubov-Born-Green-Kirkwood-Yvon equations for the particle group distribution functions. We have investigated the number of high-energy phenomena: (1) the emission of atoms and molecules with high energies from the abruptly opened surface of a condensed system; (2) the implosion of convergent streams of high-energy particles, accompanied by a phenomena of their shock dissociation and ionization, with a subsequent formation of partially ionized plasma; and (3) the recombination processes inside a plasma leading to a formation of molecules with high kinetic energies. The initiation of an earthquake occurs due to an abrupt opening of a cavity in the fluid-saturated medium. At certain thermodynamic conditions, the work function of atoms and molecules from the surface of the system may take negative values. As a result, the emission of molecules of fluids from the cavity walls will generate the high-speed streams of molecules. The emitted flux of molecules leads to the phenomena of implosion, impact dissociation, and ionization of the molecules. This plasma state of the medium is sufficient for an explosion. The explosion initiates a self-supporting chain of consequent explosions in a plane of the tectonic fault. As an example, we have considered the Bridgman explosion of serpentinite.

流体饱和环境中震源的初始高能现象

与弱断层有关的实验数据需要构造地震震源的微观模型。这项研究提出了一种新的高能机理，它将饱和了自由流体或有界流体的地层势能转化为岩石运动的动能。所提出的方法依赖于经典统计理论的框架。纳米级的高能现象是由作用在单个颗粒上的自洽分子场产生的。使用Bogolyubov-Born-Green-Kirkwood-Yvon方程对颗粒群分布函数进行分析。我们研究了许多高能现象：（1）凝聚系统突然打开的表面发射出高能原子和分子；（2）高能粒子会聚流的内爆，伴随着它们的冲击分解和电离现象，随后形成部分电离的等离子体；（3）等离子体内部的重组过程导致形成具有高动能的分子。地震的发生是由于流体饱和介质中空腔的突然打开而引起的。在某些热力学条件下，来自系统表面的原子和分子的功函可能取负值。结果，从腔壁发射出的流体分子将产生分子的高速流。发射的分子通量导致分子内爆，冲击解离和电离现象。介质的这种等离子体状态足以爆炸。爆炸在构造断层的平面中引发了随之而来的爆炸的自支撑链。例如，我们考虑了蛇纹石的布里奇曼爆炸。
