A pressure ridge is a topographic ridge produced by compression.
Depending on the affected material, "pressure ridge" may refer to:
Pressure ridge (ice), between ice floes[1]
Pressure ridge (lava), in a lava flow[1]
Pressure ridge (seismic), in a fault zone[1]
In a seismic context, a pressure ridge can range in size from a few-metres-long mound, to a kilometres-long lateral ridge.[2] It is the result of one or several earthquakes occurring on certain types of fault geometries, such as compressional bends or stepovers along strike-slip faults.[2][3] A pressure ridge can for instance be the result of a deep-set obstruction on the fault plane, which leads to material being pushed up during earthquakes.[2]
