Seismographs in Missouri a Success – The USArray Transportable Array
February is Earthquake Awareness Month in Missouri – Public events planned
The USArray Transportable Array is a network of 400 high-quality broadband seismographs that are being placed in temporary sites across the conterminous United States from west to east, and Alaska, in a regular grid pattern. With station spacing of about 70 km, Transportable Array data are extremely useful for mapping the structure of Earth’s interior. After a residence time of two years, each instrument is picked up and moved to the next carefully selected location on the eastern edge of the array. When completed, nearly 2,000 locations will have been occupied during this program. In August 2007, the first footprint was established from north to south along the westernmost quarter of the United States.
Array systems were acquired with funds provided to the Incorporated Research Institutions for Seismology (IRIS). Support for IRIS comes from the National Science Foundation (including the EAR Instrumentation and Facilities Program, EarthScope, and Office of Polar Programs), other federal agencies, universities, and private foundations. Read the POPSCI article announcing EarthScope as one of the Universe's Ten Most Epic Projects.
Station Listing -- From this site, one can review ground motion reports for the 11 stations that reside in Missouri and those currently located in other states. Many are on private property and like other outdoor adventures it is important to respect private and public property rights.
Initially, stations were located at (or near) these Missouri towns. Those indicated in bold text were placed in 2010 and the remaining stations were placed in 2011.
