近日，法国斯特拉斯堡大学Cécile Doubre团队揭示了泥火山动荡和6级断层滑动的远距离动态触发。这一研究成果发表在2025年9月4日出版的《科学》杂志上。

众所周知，大地震产生的地震波会引发遥远断层的滑动，但其潜在机制尚不清楚。

利用干涉合成孔径雷达和当地大地测量和地震数据，研究组发现距离1000公里，2023年2月的Kahramanmara基耶东南部的地震引发56座泥火山的变形和（或）喷发，并在西里海地区富含流体的库拉盆地内数十公里的7条断层上引发厘米级地震滑动。这一瞬时变形事件的等效弯矩震级为6.1，与主要油气田下方的局部膨胀相结合。研究组假设地震波引起了深部孔隙压力的变化，进而引发了沿若干断陷盆地及其周围的地震滑动。

Abstract: Seismic waves from large earthquakes are known to trigger slip on distant faults, but the underlying mechanisms remain unclear. Using interferometric synthetic aperture radar and local geodetic and seismic data, we show that the 1000-kilometer-distant, February 2023 Kahramanmara earthquakes in southeastern Türkiye triggered deformation and/or eruption at 56 mud volcanoes and centimeter-scale aseismic slip on seven faults over tens of kilometers within the fluid-rich Kura Basin in the West Caspian region. This transient deformation event, with an equivalent moment magnitude of 6.1, was coupled with local inflation below major hydrocarbon fields. We postulate that seismic waves led to a change in pore pressure at depth, which in turn triggered aseismic slip along several crustal faults crossing the basin and its surroundings.
