Seismic gap reveals vertical decoupling of shallow and deep tectonic strain

By PulseAugur Editorial · [1 sources] ·

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.

    Juxtaposition of Shallow Reservoir-Triggered Seismicity and Deep Tectonic Locking in the Qiaojia-Dongchuan Seismic Gap

    arXiv:2607.19606v1 Announce Type: cross Abstract: Identifying the critical state of mature seismic gaps is challenging, especially when anthropogenic stress perturbations, such as reservoir impoundment, superimpose on tectonic loading. Here, utilizing a high-resolution dense arra…
