Answer: You will have to do some research on this yourself, either in journals
or books or at another web site.
A good first book reference in general for this sort of information
is
Stover and Coffman, (1993) Seismicity of the United States, 1568-1989
(Revised), U.S. Geological Survey professional Paper 1527. (This
reference ought to be at a large library or can be purchased from
the Government Printing Office or the USGS: email .)
In this reference there is likely to be a brief article on this
particular quake, but also information on other historical earthquakes
in the vicinity. In the article there will be references to primary
data about the earthquake. Your questions about where the fault
is and how much the ground was altered are likely to be answered
in one or more of those references, which ought to be available
at a good university library.
A good first web site for this sort of information is to go to
the USGS site for the seismic history of the state where the earthquake
is located, visit
http://neic.usgs.gov/neis/states/states.html
and use the link for state by state historical seismicity for the
particular state. There are a lot of links there worth following
up. If the earthquake you are interested in is sufficiently large,
you may be able to find substantial information about that quake
at that link. Also there may be links to a state geological survey
which may have the information you want. |
