3-D Model: Port Hills Faults
One oblong perspex covered 3-D model of the fault plains that ruptured to cause the 22 February and 13 June 2011 earthquakes; top of the model also acts as a map overlay.
This model provides a visual demonstration of the geological forces that caused the 22 February and 13 June 2011 earthquakes. These forces were so strong that parts of the Port Hills have risen by more than 40 cm. During the 6.3 magnitude 22 February 2011 earthquake, slip of more than 2.5 m occurred 4 km underground. The south side of the fault moved generally up and west, while the north side moved down and east. In comparison, the 6.4 magnitude 13 June 2011 earthquake had a maximum slip of 1.5 m at 4-5 km underground. This model provides a simple interpretation of the observed ground displacement data that occurred in the 22 February and 13 June 2011 earthquakes, making the science behind the events understandable.
