The initiation of intraslab earthquakes and their location depend on multiple factors such as slab heterogeneity, pre-subduction anisotropy, thermal parameters and the metamorphic history of the lithosphere slab. As a result, these failures occur over a range of temperature-pressure conditions through different mechanisms. Therefore, to unravel the intricacy of intraslab seismicity, it is crucial to investigate the details of failure mechanisms using multiple datasets, at different scales. Details on rupture mechanisms are now accessible through advanced, high-resolution seismologic approaches. However, seismologic archives are limited to events of the past few decades. Further, quasi-synchronous multiple-source mechanisms can be challenging to distinguish from seismic data only. Alternatively, the geologic records of intraslab seismicity, preserved in pseudotachylytes, provide a higher spatiotemporal resolution than seismic data, resulting in direct insight into the rupture triggering mechanisms.. These fault rocks also inform, over the geologic timescale, on the integrated deformation history of the slab. Despite this fact, only a handful of natural exposures have been investigated, and these include localities in Corsica, Italy, Zambia, and Japan. In addition, despite some strain rate limitations, deformation experiments, conducted using a wide range of starting materials and over broad pressure-temperature conditions, may further constrain the causes of intraslab rupture. These experiments, being intrinsically performed on relatively small rock volumes cannot capture large scale aspects of intraslab deformation. Finally, numerical modelling may overcome some of the above limitations as long as accurate and realistic parameters are chosen. Ultimately, our review shows that to fill the gap in our knowledge of intraslab seismicity, we need a multiscale-multimethod approach that integrates seismologic, geologic, experimental and numerical perspectives.

板内地震的发生及其位置取决于多种因素，如板片非均质性、俯冲前各向异性、热参数和岩石圈板片的变质历史。因此，这些故障会通过不同的机制在一系列温度-压力条件下发生。因此，要解开板内地震活动的复杂性，使用不同尺度的多个数据集研究失效机制的细节至关重要。现在可以通过先进的高分辨率地震学方法获得有关破裂机制的详细信息。然而，地震档案仅限于过去几十年的事件。此外，准同步多源机制可能难以仅与地震数据区分开来。或者，板内地震活动的地质记录，保存在拟快速液中，提供比地震数据更高的时空分辨率，从而直接了解破裂触发机制。这些断层岩还在地质时间尺度上告知板块的综合变形历史。尽管如此，仅对少数自然暴露进行了调查，其中包括科西嘉岛、意大利、赞比亚和日本的地区。此外，尽管存在一些应变率限制，但使用多种起始材料和在广泛的压力-温度条件下进行的变形实验可能会进一步限制板内破裂的原因。这些实验本质上是在相对较小的岩石体积上进行的，无法捕捉板内变形的大规模方面。最后，只要选择准确和现实的参数，数值建模就可以克服上述某些限制。最终，我们的回顾表明，为了填补我们在板内地震活动知识方面的空白，我们需要一种综合地震学、地质学、实验和数值观点的多尺度多方法方法。
