Very curious about earthquakes.....does anyone know?
ok, so California has been having quite a few earthquakes lately....I have heard that frequent small earthquakes are good because it take off pressure......BUT I have also heard that these frequent earthquakes indicate the coming of a very BIG one....does anyone know which is true if any??

During this last week California has had over 500 earthquakes. Of these only two were large enough to feel - and even those would be a bit of a rattle and that's all. This is very normal for the state.
A large earthquake (6 or above) delivers many thousands of times as much energy as a 2 magnitude. This means a fault would have to have many thousands of 2 magnitude earthquakes to relieve enough strain to prevent a large quake. That's just not happening. Also, while small quakes may be relieving pressure *here*, they might well be adding more pressure *there*. It's a very complex system.
Any earthquake of any size might be a warning of a larger one coming. These are known as "foreshocks". We just don't know how to tell if any single quake is a foreshock or not. Different areas seem to behave differently. California, for whatever reason, doesn't seem to get many foreshock earthquakes. In contrast, China does. Go figure!

You can take it on either way. Because I have sensed very feeble earthquake on 5th april 2005.Nothing happened after wards.But on 24th July 2005 I sensed same type of feeble earthquake waves. After 6 hours a major earthquake of 7.3 in Richter scale recorded from a distance of about 1400 K/M from our place. Nothing is perfectly predictable.Be ready to move to a safer place always if you are living in seismic zone 4 or 5.Source(s): My research work.

it may be true but sometimes they do predict one that can split the nation well that's what i heardSource(s): neighbor hood
