Abstract This study aims to analyze the complex relationship between heat flow and seismicity in tectonically active zones worldwide. The problem was quantitatively analyzed by using a geographic detector method, which is well suited for analyzing nonlinear relationships in geography. Moreover, β-value that describes the frequency-magnitude distribution is used to represent the seismicity. The results showed that heat flow (HF) = 84 mW/m2 is a critical point for the relevant mechanisms of heat flow with seismicity in these zones. When HF < 84 mW/m2, the heat flow correlates negatively with the β-value, with a correlation degree of 0.394. Within this interval, buoyant is a primary control on the stress state and earthquake size distribution. Large earthquakes occur more frequently in subduction zones with younger slabs that are more buoyant. Due to zones with a high ratio of large earthquake corresponds to low β-values, high heat flow values correspond to low β-values. When HF > 84 mW/m2, the heat flow correlates positively with the β-value, with a correlation degree of 0.463. Within this interval, the increased heat flow decreases the viscosity of the rock plate and then reduces the stress. Lower stress would correspond to a smaller earthquake and then a higher β-value. Therefore, high heat flow values correspond to high β-values. This research would be conducive to understand the geologic activity and be helpful to determine the accuracy and timeliness of seismic hazard assessment.

全球构造活动带热流与地震活动的关系

摘要 本研究旨在分析全球构造活动带中热流与地震活动之间的复杂关系。使用地理检测器方法对该问题进行了定量分析，该方法非常适合分析地理学中的非线性关系。此外，描述频率-震级分布的β值用于表示地震活动。结果表明，热流 (HF) = 84 mW/m2 是这些区域中热流与地震活动相关机制的临界点。当 HF < 84 mW/m2 时，热流与 β 值呈负相关，相关度为 0.394。在这个区间内，浮力是对应力状态和地震大小分布的主要控制。大地震更频繁地发生在具有更年轻浮力的板块的俯冲带。由于大地震比率高的区域对应于低 β 值，高热流值对应于低 β 值。当 HF > 84 mW/m2 时，热流与 β 值呈正相关，相关度为 0.463。在这个区间内，增加的热流降低了岩石板的粘度，进而降低了应力。较低的应力将对应于较小的地震，然后是较高的 β 值。因此，高热流值对应于高 β 值。该研究将有助于了解地质活动，有助于确定地震危险性评估的准确性和及时性。相关度为 0.463。在这个区间内，增加的热流降低了岩石板的粘度，进而降低了应力。较低的应力将对应于较小的地震，然后是较高的 β 值。因此，高热流值对应于高 β 值。该研究将有助于了解地质活动，有助于确定地震危险性评估的准确性和及时性。相关度为 0.463。在这个区间内，增加的热流降低了岩石板的粘度，进而降低了应力。较低的应力将对应于较小的地震，然后是较高的 β 值。因此，高热流值对应于高 β 值。该研究将有助于了解地质活动，有助于确定地震危险性评估的准确性和及时性。
