Are volcanoes distributed are they scattered evenly or concentrated in zones?

Answer 1

Stress in the earth's outer layer cause a pushing effect against the sides of the fault. Due to this motion, rocks slip or collide against each other releasing energy. This released energy travels in waves through the earth's crust and causes the shaking that we feel during an earthquake.

Under the surface of the earth, the two sides of a fault are constantly moving, relative to one another. This movement is known as a fault slip. The movement of these two sides is not smooth and is accompanied by a gradual build-up of elastic strain energy within the rocks along the fault.

Eventually, the strain along the fault becomes too much.The fault then ruptures with a sudden movement releasing all the energy it has built up. This energy is released in the form of vibrations called 'seismic waves'.

These waves travel along the surface and through the earth at varying speeds depending on the material through which they move. It is actually these seismic waves that cause most of the destructive effects, which we associate with earthquakes.

The location on a fault where the slip first occurs is called the hypocentre, whereas the position directly above it on the ground surface is called the epicentre.

When these seismic waves reach the surface of the earth, they give rise to strong ground motion causing building and other man-made structures to shake or collapse or develop cracks and fissures.

Earthquakes can also cause landslides, sudden eruptions as in the case of a hot lava flow from a volcano or giant waves called tsunamis. Sometimes new land mass are also formed.

I think that they are in concentrated zones, not just randomly, to answer the REAL question. (I didn't write the other stuff but I wouldn't want to erase somebody's work)

Answer 2

No. There is randomness or chance involved in whether an earthquake will occur in "earthquake prone areas" but their occurrence does not follow a completely spatial random pattern (csr pattern). A csr pattern requires that every location in a space has the same probability of an event occurring. You can see the density map of earthquakes in the US and other areas in this map: http://earthquake.usgs.gov/regional/states/us_density.php Also, geologists are able to identify which areas in the world are more prone to earthquakes.

Answer 3

Volcanoes are only found on the edges of techtonic plates. An other thing to look out for is that they occur occur on certain margins, not every plate boundary has volcanoes. They are found in zones, e.g. the ring of fire.

Answer 4

Well theres falt lines thats all we basically know but we will find more soon i bet

Answer 5

No and nobody loves you!
