It is generally accepted that tectonic earthquakes may trigger volcanic activity, although the underlying mechanisms are poorly constrained. Here, we review current knowledge, and introduce a novel framework to help characterize earthquake-triggering processes. This framework outlines three parameters observable at volcanoes, namely magma viscosity, open- or closed-system degassing and the presence or absence of an active hydrothermal system. Our classification illustrates that most types of volcanoes may be seismically-triggered, though require different combinations of volcanic and seismic conditions, and triggering is unlikely unless the system is primed for eruption. Seismically-triggered unrest is more common, and particularly associated with hydrothermal systems.
人们普遍认为构造地震可能引发火山活动，尽管其潜在机制尚不清楚。在此，我们回顾当前的知识，并引入一个新的框架来帮助描述地震触发过程。该框架概述了在火山上可观测到的三个参数，即岩浆粘度、开放或封闭系统的脱气以及是否存在活跃的热液系统。我们的分类表明，大多数类型的火山可能会被地震触发，尽管需要不同的火山和地震条件组合，而且除非系统处于喷发准备状态，否则触发不太可能发生。地震引发的动荡更为常见，尤其与热液系统有关。
