Earthquakes, geometry, the mantle wedge and tsunami
Any country that borders the ocean is prone to tsunami and New Zealand is no exception.
During great subduction earthquakes (magnitude > 8) to the north of New Zealand the densely populated coastal areas on the north coast may not experience shaking that is significant enough to trigger effective and widespread self-evacuation.
A tsunami-generating earthquake in this region could potentially leave tens of thousands of people exposed; a risk which must be addressed by supplementing natural warning with a cautious interpretation of available instrumental data.
For optimal reduction of loss of life during large regional earthquakes, self-evacuation messaging must be carefully explained and supplemented with scientific monitoring and alerting mechanisms to protect vulnerable populations.
