Risks from induced earthquakes are a growing concern that needs effective management. For hydraulic fracturing of the Eagle Ford shale in southern Texas, we developed a risk-informed strategy for choosing red-light thresholds that require immediate well shut-in. We used a combination of datasets to simulate spatially heterogeneous nuisance and damage impacts. Simulated impacts are greater in the northeast of the play and smaller in the southwest. This heterogeneity is driven by concentrations of population density. Spatially varying red-light thresholds normalized on these impacts [moment magnitude (M_w) 2.0 to 5.0] are fairer and safer than a single threshold applied over a broad area. Sensitivity tests indicate that the forecast maximum magnitude is the most influential parameter. Our method provides a guideline for traffic light protocols and managing induced seismicity risks.

诱发地震的风险日益引起人们的关注，需要进行有效的管理。对于德克萨斯州南部的Eagle Ford页岩的水力压裂，我们开发了一种风险预警策略，用于选择需要立即关闭井眼的红灯阈值。我们使用数据集的组合来模拟空间异质性的滋扰和破坏影响。在戏剧的东北部，模拟的影响较大，而在西南部，模拟的影响较小。这种异质性是由人口密度的集中驱动的。根据这些影响归一化的空间变化红光阈值[力矩幅度（M _w）2.0到5.0]比在宽广的区域应用单个阈值更公平，更安全。敏感性测试表明，预测的最大震级是最有影响力的参数。我们的方法为交通信号灯规程和管理诱发的地震危险性提供了指南。
