Kāpiti is a tectonically active area. There are five known faults traversing the area:
New Zealand lies on the boundary of the Pacific and Australian tectonic plates. The plates push against each other, along a curving boundary, at a steady rate. The plate boundaries become more and more stressed until eventually something has to give – and an earthquake occurs along a fault somewhere in the plate boundary
While we often feel small earthquakes that don’t cause much damage, many of the active faults in the region are capable of producing large earthquakes.
An earthquake can occur at any time. There is no early warning, the first sign of a quake is often a rumbling sound followed by rolling and shaking.
Hazards are associated with earthquakes
There are a number of hazards associated with earthquakes including fault/ground rupture, liquefaction, ground shaking, land slides and tsunami. Each of the earthquake hazards is likely to affect different areas within the District.
Kāpiti Coast Combined Earthquake Risk Maps (PDF, 4 pages, 577Kb)
In a major earthquake the ground may rupture, with ruptures typically occurring along existing fault traces. This could involve horizontal and/or vertical movement of several meters
Ground shaking causes some soils to behave like a liquid, causing structures to sink, tilt or topple over
Violent ground shaking could last up to a minute in a large earthquake. It may be difficult to remain standing during an earthquake. Several hundred aftershocks could be felt in the weeks following the main quake.
Damage from earthquake-induced landslides can range form severely weakened foundations and structural failures, to total destruction.
Tsunami are long, deep, fast travelling ocean waves propagated by a displacement of water caused by earthquakes, landslides or volcanic eruptions beneath or near the ocean.
