Seismic gap reveals vertical decoupling of shallow and deep tectonic strain

Researchers have identified a critical state in the Qiaojia-Dongchuan seismic gap, revealing a vertical decoupling mechanism between shallow and deep seismic activities. Shallow seismicity, influenced by fluid-driven reservoir-triggered events, shows high b-values, while deeper seismic activity indicates a locked asperity with significant Coulomb stress accumulation. This decoupling model suggests that shallow induced seismicity can obscure the silent buildup of deep tectonic strain, offering a new framework for assessing seismic risks in reservoir-fault systems worldwide.
