Pressure ridge

Summary
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
  • Pressure ridge (lava), in a lava flow
  • Pressure ridge (seismic), in a fault zone
In a seismic context, a pressure ridge can range in size from a few-metres-long mound, to a kilometres-long lateral ridge. 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. 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. See also
  • Ridge (meteorology), an elongated area of relatively high atmospheric pressure
