Tectonic "short circuit" of sub-horizontal fluid-saturated bodies as a possible mechanism of the earthquake

TL;DR

This paper proposes a novel earthquake mechanism involving the collapse of sub-horizontal fluid-saturated bodies caused by fluid pressure redistribution, which may trigger seismic activity through structural shifts and foreshock effects.

Contribution

It introduces a new model emphasizing fluid pressure dynamics in sub-horizontal bodies as a primary earthquake trigger, contrasting traditional stress-based explanations.

Findings

Collapse of SHFB can induce seismic shocks.

Fluid redistribution causes shifts in rock blocks.

Mechanism explains foreshocks and aftershocks.

Abstract

An alternative earthquake mechanism is proposed. The traditional stress mechanism of fracture formation assigned a support role. As a proximate cause of the earthquake the destruction of the roofs of sub-horizontal fluid-saturated bodies (SHFB) is considered. This collapse may occur due to redistribution of fluid pressure within the system of SHFB connected by cracks (tectonic or other nature). It can cause both shifts of rock blocks contributing to seismic shocks and various effects characteristic of foreshocks and aftershocks.
