Type of topographic ridge
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/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.
