Hi all,

I've been looking to collect a dataset of seismograms for an
'earthquake prediction competition' idea (see below for more
information), and struggling quite a lot along the way!

Hi Dan,

Sorry, but there is NO chance of this simplistic approach succeeding. =
I suggest that you buy or borrow a copy of "Predicting the Unpredictable: T=
he Tumultuous Science of Earthquake Prediction", by Susan Hough. It is not =
expensive, well worth reading and describes most of the previous attempts a=
nd ideas on Earthquake Prediction!
Earthquakes are sudden slip movements in the Earth's crust, somewhere b=
etween ground level and 700 km down. Some are volcanic in origin, but most =
are due to the 7 major and 8 minor Earth's Tectonic Plates moving relative =
to one another or diving under each other, at rates of typically 0 to100 mm=
per year. The quakes are often on fault lines, but these may be hundreds o=
f miles long and there are thousands of them. Some large quakes do repeat, =
but there may be anything up to several hundred years in between them. Only=
quakes greater than M6.5 can be detected all over the Earth. Some large qu=
akes just go bang, without any precursor quakes.=20
