The Idrija Fault (pronounced [ˈiːdrija]; Slovene: Idrijski prelom) is a seismically active fault in Slovenia.[1][2] It strikes NW–SE and the fault plane dips towards the northeast. The activity along the fault started in the Miocene with normal faulting and changed to dextral strike-slip in Pliocene. The fault was first described by Marko Vincenc Lipold, a geologist from Slovenia.[3][4]

Present displacement is measured and varies along strike but is in the order of magnitude of 0.1 mm per year.[3] The strongest earthquake along the Idrija Fault was the 1511 Western Slovenia earthquake (or 1511 Idrija earthquake), which took place on 26 March 1511, had a magnitude of 6.8, and caused about 12,000 deaths.[3][5][6]
