The exact locations of
the monitors are not disclosed to
protect the integrity of the data they are collecting. Chris Hayward,
director of SMU Geophysics Research Projects and leader of SMU’s monitor
installation team, explains what makes a good site:
“First of all, we
want the site to be in the right location relative to the seismic
events. We'd like to have stations located at distances both near and
far from the epicenter.
“Second, we want
the stations to be seismically quiet – away from sources of vibration
such as people walking, heavy traffic, and motors and pumps.
“Third, we like a
site that will be unobtrusive for a year or longer. That means finding
a site where the monitor is not in the way and doesn’t interfere with
day-to-day activities of people living or working on site.
“Finally, we prefer
to locate monitors near AC power and an Internet connection. It isn't
essential -- if we have met the other three requirements for a good
location, we can still install a station, but that involves installing a
cell phone connection.”
