发生在2020年3月26日的5级Mentone地震，是过去20年来在美国主要石油产区特拉华盆地西德克萨斯州发生的最大地震。此外，许多水力压裂和废水处理井分布在该地区。在距离主震30公里的范围内，有8口II级注水井用于工业废水处理，目标是深层多孔Ellenburger含水层，2012-2020年期间平均每月1.36 × 106桶（BBL）。流体扩散的孔隙弹性模型显示，这些附近的注入器在主震位置共同传递了高达80.5 kPa的库仑应力，能够触发这一M5级事件。假设Mentone事件发生在孔隙压力增加最大时，则注入峰值与M5发生之间的时间延迟对应于Ellenburger含水层的最佳渗透率为6.76 × 10‐14 m2，与独立估计一致。
The M5 Mentone earthquake that occurred on March 26, 2020, was the largest event recorded over the last 2 decades in West Texas within the Delaware Basin, a U.S. major petroleum‐producing area. Also, numerous hydrofracturing and wastewater disposal wells are spread across this region. Within a 30 km distance to mainshock, eight class‐II injection wells for industrial wastewater disposal target the deep porous Ellenburger aquifer at an average rate of 1.36 × 106 barrel (BBL) per month during 2012–2020. Poroelastic models of fluid diffusion show these nearby injectors collectively imparted up to 80.5 kPa of Coulomb stress at the mainshock location, capable of triggering this M5 event. Assuming the Mentone event occurs when pore‐pressure increase is maximum, the time delay between peak injection and the M5 occurrence corresponds with an optimal permeability of 6.76 × 10‐14 m2 for the Ellenburger aquifer layer, in agreement with independent estimates.
