why there is corelation between earthquake epicenter and the megacities?

Answer 1

There is something of a correlation between them, although I don't know how strong it is. However, if you think about it, it makes some sense that people would live in areas more prone to large earthquakes. Unlike what another responder said, it's not just pure coincidence.

Areas that are heavily populated usually are so because of significant natural resources, like good agriculture or boat harbors. These areas are also quite scenic, in that they provide strong geographic relief (big hills or mountains) from, say, a flat plain. Well, you might ask, why is it not a flat plain? It's because of geologic activity, be it a volcano, or tectonic fault motion, etc.

Think of all the people who live near active volcanos. There's good farming there, because of the mineral-rich soils. Those minerals are there because of the volcano. People are accepting the risk of being destroyed by the volcano (a small risk) for the benefit of farming its productive results. California is a beautiful place, heavily populated, especially in the past 50 years. It's a great place to live with its amenable climate. But it wouldn't have that climate or its terrain without the geologic history that produced it (and is still producing it!).

Answer 2

No correlation. Just coincidence.

People like to build big cities near the ocean both for recreation and marine food sources. Around the outside edge of the Pacific Ocean there are subduction zones, where one tectonic plate slides under another. This is a source of many volcanoes and earthquakes. Large cities in earthquake prone areas is coincidence ... and bad planning!

Answer 3

i don't be attentive to if there's a correlation. If by skill of "megacities" you advise super metropolitan aspects, then i do no longer think of there's a correlation in any respect. it is in basic terms a human brainfart :) We geared up interior the incorrect places with stable reason. the place one shows quakes, one will additionally in many situations discover captivating geology (i.e. mountains and valleys) that are, of direction, the effect of the quakes and the moving of continental plates. the place one shows captivating geology, one will additionally discover wealthy yuppies who pick to outlive a hill-area :)

Answer 4

It is not correct. But due to the density of the people living in mega city is more and the buildings are also more you will find more damages in city. You may think just because we load more materials near magacities the artificial pressure developed by human activities causes the quakes. Comparing the force released the loaded materials because of the human activities are much less . Please visit my slide show to understand the force released by earthquakes.My web site
