At least two people have died in the magnitude 7.5 earthquake that struck New Zealand's South Island early on Monday.
Preliminary modelling suggests that the earthquake was caused by a rupture of a northeast-striking fault that projects to the surface offshore.
But this may be a complex event, involving several faults on the South Island.
The seismic energy, released over two minutes, came from the rupture of a roughly 200km-long fault system.
The northern part of the South Island straddles the boundary between the Pacific and Australian tectonic plates.
