Scientists Create First Earthquakes In The Laboratory 15 Nov 2002 Scientists
at University College London have for the first time created earthquakes
in the laboratory in order to better understand their mechanics. The UCL
scientists used a multianvil press to compress rocks similar to those
found deep in the earth to pressures and temperatures of extreme
magnitude, recreating the conditions hundreds of kilometres below the
earth's subduction zones. By doing so, scientists hope to understand what
causes intermediate and deep focus earthquakes. The cause for such
earthquakes has remained a mystery. The
largest deep earthquake ever recorded was at magnitude 8.3 and occurred
600 km below "Deep
and intermediate focus earthquakes are an important and mysterious class
of earthquakes, Understanding these deep earthquakes could be the key to
unlocking the remaining secrets of plate tectonics". Says Dr David
Dobson.
