Choosing Sites for Seismic Monitors

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: 

Earthquake Study Monitor“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.”
