The North Anatolian Fault (NAF; Turkish: Kuzey Anadolu Fay Hattı) is an active right-lateral strike-slip fault in northern Anatolia, and is the transform...

An asperity is an area on an active fault where there is increased friction, such that the fault may become locked, rather than continuously slipping...

The Philippine fault system is a major inter-related system of geological faults throughout the whole of the Philippine Archipelago, primarily caused...

often kept in the form of an active alarm list such as is defined in RFC 3877, the Alarm MIB. A list of cleared faults is also maintained by most network...

maps of the surface traces of known active faults. These maps include both the best known location where faults cut the surface and a buffer zone around...

the fault was active during the Permian-Cambrian, movement possibly accompanied by earthquakes took place during the Holocene and formed the fault scarp...
