Earthquakes occur here due to the unique geology of new zealand new zealand is situated on the edge of both the australian and pacific tectonic plates.
Earthquake in the ocean floor.
Amazing video showing what happens at the sea bed during a massive earthquake.
While a part of the san andreas fault near and north of san francisco is offshore the motion is mostly horizontal so it will not cause large vertical motions of the ocean floor that would generate a tsunami.
The epicenter is the point on the earth s directly vertically above the focus.

The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.
Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around.
The video was recorded by diver jan paul rodriguez and shows a calm seabed in.
Those earthquakes happened on subduction zone faults on which fault slip caused vertical uplift of the sea floor.
Plate tectonics and the ocean floor.
The different ways in which tectonic plates rub against each other under the ocean or sea floor to create submarine earthquakes.
Armed with these simulation results noaa s tsunami warning centers are then able to forecast flooding in the event of an earthquake generated tsunami.
For earthquakes occuring on the ocean floor this is the point where schock waves originate.
This seismic activity lifted the sea floor 2 meters 6 6 feet.
These models simulate offshore earthquakes the resulting tsunami movement across the ocean and the magnitude and location of coastal flooding caused when a tsunami reaches the shore.
Some of the main areas of large tsunami producing submarine earthquakes are the pacific ring of fire and the great sumatran fault.
The type of friction created may be due to the characteristic of the geologic fault or the plate boundary as follows.
