We have estimated empirical relationships that associate the age of the Pacific oceanic lithosphere with the seismic energy released on both flanks of the East Pacific Rise. The equations found were tested by comparing other empirical equations based on lithospheric age, heat flow, and bathymetric depth published by other authors. The results of this study are consistent for seafloor ages ranging between 1 and 4 Ma throughout three perpendicular cross-sections. These cross-sections are located between the diverging plate boundary of the northern Pacific Ocean up to the subduction zone of western Mexico. Our results allow us to infer the depth of the 1200 °C isotherm underneath the analyzed plates, from the mid-oceanic ridges up to the subduction zones. The distribution of seismic energy released within the limits of the Rivera and Pacific plates shows a gradual decrease from the ridge axis to the oceanic trench. However, an increase of seismic activity is recorded near the Mesoamerican Trench, where the Rivera Plate subducts under the North American Plate at an angle of ~ 46°. This anomaly is a consequence of the convergence, thrust and deepening of the oceanic plate. Due to the homogeneity of this plate, it is possible to infer the projection of isochrones in the subduction zone. Although the thickening of the thermal boundary layer may be estimated from the square root function of the seismic energy, this brittle–ductile transition in the subduction zone deepens exponentially with relation to the computed energy.

释放的年轻大洋板内地震能量的变化与岩石圈年龄有关。对东太平洋上升及其与里维拉俯冲带的融合的影响

我们估计了经验关系，这些关系将太平洋岩石圈的年龄与东太平洋上升沿两侧释放的地震能量相关联。通过比较基于其他作者发表的岩石圈年龄，热流和测深的其他经验公式，对找到的公式进行了测试。这项研究的结果对于在三个垂直横截面上的1至4 Ma的海底年龄是一致的。这些横截面位于北太平洋的发散板块边界之间，一直到墨西哥西部的俯冲带。我们的结果使我们能够推断出从洋中脊到俯冲带，被分析板块下方1200°C的等温线深度。在里维拉和太平洋板块范围内释放的地震能量分布表明，从山脊轴线到海洋海沟逐渐减小。但是，在中美洲海沟附近记录到地震活动增加，那里的里维拉板块以约46°的角度在北美板块下俯冲。这种异常是海洋板块汇聚，推力和加深的结果。由于该板的均匀性，可以推断出等时线在俯冲带中的投影。尽管可以根据地震能量的平方根函数估算热边界层的厚度，但俯冲带中的脆性-延性转变相对于计算出的能量呈指数级加深。在中美洲海沟附近记录了地震活动的增加，里维拉板块在北美板块下方以〜46°的角度俯冲。这种异常是海洋板块汇聚，推力和加深的结果。由于该板的均匀性，可以推断出等时线在俯冲带中的投影。尽管可以根据地震能量的平方根函数估算热边界层的厚度，但俯冲带中的脆性-延性转变相对于计算出的能量呈指数级加深。在中美洲海沟附近记录了地震活动的增加，里维拉板块在北美板块下方以〜46°的角度俯冲。这种异常是海洋板块汇聚，推力和加深的结果。由于该板的均匀性，可以推断出等时线在俯冲带中的投影。尽管可以根据地震能量的平方根函数估算热边界层的厚度，但俯冲带中的脆性-延性转变相对于计算出的能量呈指数级加深。由于该板的均匀性，可以推断出等时线在俯冲带中的投影。尽管可以根据地震能量的平方根函数估算热边界层的厚度，但俯冲带中的脆性-延性转变相对于计算出的能量呈指数级加深。由于该板的均匀性，可以推断出等时线在俯冲带中的投影。尽管可以根据地震能量的平方根函数估算热边界层的厚度，但俯冲带中的脆性-延性转变相对于计算出的能量呈指数级加深。
