IRIS Knowledge Base

There are many factors that go into selecting a successful Transportable Array site. The TA stations are laid out in a grid with ~70 km spacing. Proposed sites must be near these grid markers (you can find out whether a specific location is within the spacing limitations by using the Suggest a Site tool). Other considerations include vehicle accessibility, distance from environmental noise sources such as major roads or railways, sunlight for solar panels, ease of construction, and likelihood of adverse events such as flooding or vandalism.
