Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics the outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle.
Earthquake in the ocean floor.
For earthquakes occuring on the ocean floor this is the point where schock waves originate.
The type of friction created may be due to the characteristic of the geologic fault or the plate boundary as follows.
The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.
The different ways in which tectonic plates rub against each other under the ocean or sea floor to create submarine earthquakes.
The earthquake focus is the point wherein the rocks start to crack and where pressure is released.
Plate tectonics and the ocean floor.
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.

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.
Some of the main areas of large tsunami producing submarine earthquakes are the pacific ring of fire and the great sumatran fault.
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.
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.
